Myopia is a condition in which a person needs “minus” power spectacles, to focus light rays on the retina and provide accurate vision. ARMD is a degenerative disease of the retina that causes progressive loss of central vision, leaving only the side vision intact. Although the wet form of ARMD is less common, the chance for severe and rapid loss of vision is much greater.
While ARMD rarely causes total blindness, the loss of central vision may make everyday activities extremely difficult. If you have macular degeneration and you suddenly notice new distortion or a new blank spot in your vision, you should notify your eye care professional immediately. You can monitor your vision by either regularly covering one eye and looking at a straight.
Several studies have found that family history of ARMD increases the risk of developing the disease.
Photodynamic Therapy is a treatment that uses a non-thermal (or cold) laser without leaving a blind spot in the vision. Intravitreal Anti-VEGF (Vascular Endothelial Growth Factor) drugs have recently been found to be effective.
Importantly, all these treatments are aimed not primarily to improve vision but to reduce further vision loss. Regular Eye Examination: A chart called the Amsler Grid may also be used in some cases to highlight visual distortions symptomatic of ARMD. Early diagnosis through medical eye examinations at least every year offers eye care specialists the opportunity to provide appropriate options for possible treatment, rehabilitation and support services. Retina is a thin layer at the back of the eye that senses light just like the film of camera.
Diabetes causes an excessive amount of glucose to remain in the blood stream which may cause damage to the blood vessels.
An eye examination by trained personal is the best way to detect early diabetic changes in your eye. If your ophthalmologist finds diabetic retinopathy, he or she may order colour photographs of the retina or a special test called fluorescein angiography to find out if you need treatment.
In diabetic macular edema, fluid rich in fat and cholesterol leaks out of damaged vessels and accumulates in the macula. The fibrous (scar) tissue associated with the new blood vessels can shrink there by wrinkling and pulling the retina from its normal position.
Occasionally, extensive retinal vessel closure will cause new, abnormal blood vessels to grow on the iris (colored part of the eye) and block the normal flow of fluid out of the eye. For macular edema, the laser is focused on the swoller retina near the macula to decrease the fluid leakage.
Vitrectomy is a surgery needed for diabetic patients who suffer a vitreous hemorrhage or retinal detachment. Intravitreal injections may be given in the vitreous jelly of the eye to reduce diabetic macular edema. Patients undergoing any eye surgery, including cataract surgery, should have eye examination before and after surgery as retinopathy especially macular edema can worsen after surgery. Adequate control of other systemic problems such as high blood pressure, kidney disease and cholesterol control is equally important and helps in treatment. Cardiac insufficiency, or heart failure, is no longer considered, pure and simply, a heart disease.
Dyspnea and fatigue during physical activity constitute the main clinical symptoms of heart failure [5], which prompts the patient to cease the physical effort much too early.
Recent studies show tenuous correlation between the hemodynamic variables and exercise capacity [7]; an immediate increase in aerobic competence with improved heart performance [8] or with pharmacological increase of muscle blood flow [9] was not detected.
Compensatory mechanisms are unleashed to maintain the perfusion of vital organs and stabilize the heart’s performance in face of a cardiac injury, regardless of the causal agent. High concentrations of norepinephrine and angiotensin II boost the release of arginine vasopressin in the neurohypophysis and stimulate the production of endothelin in the vascular endothelium, which are additional causes of hypertrophic remodeling, apoptosis, and deterioration of cardiac function. In comparison to normal controls, the skeletal muscle microscopy of individuals suffering from heart failure revealed decreased capillary density, atrophy, remodeling, predominantly with muscle fiber type II instead of type I, which have high oxidant properties; and fewer mitochondria per cell.
Up until a few decades ago, physical activity was not recommended for individuals with chronic heart failure because it was believed it worsened cardiac function.
A recent review in the existing literature encompassed 29 studies and 1,126 individuals with primary and secondary heart failure, NYHA classes II or III and left ventricular ejection fraction (LVEF) less than 40%. Rehabilitation through physical activity improves NYHA classification of heart failure patients, exercise tolerance and even left ventricular function [28]. Regular physical exercises have direct impact on the neuroendocrine and autonomic nervous systems in cases of heart failure. There is an impressive list of benefits to skeletal muscle, such as an increase of muscle fiber type I, enhancement of phosphocreatine resynthesis, and an increase of adenosine diphosphate, intracellular pH, and phosphate to phosphocreatine ratio [38, 39, 40].
The clinical manifestations of heart failure, and more specifically in relation to effort intolerance, may be accentuated by a peripheral component associated to myocardial dysfunction.
The functional capacity of these patients is evaluated by effort tolerance, peak VO2, and oxygen consumption at the moment of anaerobic ventilatory threshold, which corresponds to the level of the exercise that accompanies the majority of the activities of HF patients [45, 46].
No relationship between dysfunction evaluated at rest and exercise capacity was observed in left ventricular systolic dysfunction. In heart failure there is greater activation of arterial and cardiopulmonary baroreflex, which aim at the preservation of arterial blood pressure. Neurohormonal system stimulation is classified as one of the main markers present in heart failure. The activation of the renin-angiotensin-aldosterone system has been attributed to low renal perfusion pressure. Picture 3a: In A (initial biopsy), fibers with a less intense coloration may be observed in SDH enzyme. Picture 3b: In B (final biopsy), it is possible to note more stained fibers, especially on its periphery.
Patients with chronic heart failure experience inequality in ventilation perfusion relation with an increase of physiological dead space. Before starting a physical activity program, heart failure patients must have been clinically stable for a period no lesser than thirty days; moreover, they must undergo an exercise test, preferably one with a direct analysis of the gases exhaled.
The intensity of the physical activity must be always individualized and progress gradually, in particular with patients with exacerbated exercise intolerance. The initial intensity recommended for aerobic physical activity is 80% of the heart rate corresponding to the O2 measured at anaerobic threshold, and may reach 100% by the end of the first month. Picture 4: Curves of oxygen uptake (O2), carbon dioxide production (CO2), minute ventilation (VE) and heart rate (HR) during cardiopulmonary test on patient referred to in Table 2. From our understanding, supervised physical training sessions should be performed at least 3 times a week, during 6 months. One of the most defined and visible effects of physical activity in these patients consists in the improvement of quality of life, due to better biomechanics with movement economy and consequent fatigue reduction, dyspnea, and optimization of psychological profile according to several studies [51,59]. Picture 6: Patients with advanced nonischemic dilated cardiomyopathy optimized with pharmacological treatment.
As for future clinical eventualities, regular physical training has been associated to lesser mortality and rehospitalization rates in a randomized controlled trial with 99 patients followed up for 14 months [63]. In spite of the beneficial effects of physical activity on the cardiovascular system, it is a fact that during intense physical activities the relative risk of cardiovascular events is greater than in regular, daily activities [65]. Exercising in a swimming pool or a sauna are not indicated for patients with heart failure [68]. Training programs conducted at home under indirect supervision have also been encouraged for patients with heart failure. As for the most appropriate intensity of exercises for heart failure patients, the issue is controversial. Conversely, most programs use low to moderate intensity levels, remaining between 60% and 70% of peak O2 [72] . Picture 7: Training in low intensity group (BI) at 67% of peak VO2 (VO2p), limited by the anaerobic threshold (AT) and the high intensity group (AI) at 88% of peak VO2, limited by the respiratory compensation point (RCP) in patients with HF. On the other hand, only in the low intensity group was it verified a significant improvement of VO2 at the anaerobic threshold, of the Minnesota Living with Heart Failure (MLHF) score, and of ventilatory efficiency as evaluated by oxygen and carbon dioxide ventilatory equivalents; moreover, there was improvement B-type natriuretic peptide (BNP) [73].
Picture 8: After 6 months of physical training only with low intensity training was there significant increase in oxygen uptake (O2) at the submaximal level, that is, at the anaerobic threshold (AT). As for ventilatory efficiency, our hypothesis is that intense training leads to higher metabolic acidosis, which in turn causes a hyperstimulation of the peripheral muscle ergoreceptors. As for autonomic balance, regular exercises promote the reduction of sympathetic hyperstimulation and circulating catecholamines, thus resulting in increased heart rate variability [48, 74]. A recent study on patients with weak respiratory muscle was published by a group from the Laboratory of Exercise Physiopathology of Hospital das Clínicas in Porto Alegre. Hence, the incorporation of breathing exercises seems to unlock new possibilities to rehab programs, especially for patients with weak ventilatory muscle. Furthermore, questions over the various pharmacological agents used in these patients’ therapeutic arsenal, some of which may lessen the physiological benefits attributed to performing exercise on a chronic basis.

At BCEIRC, we have a dedicated Vitreoretinal operating theatre, which is well equipped with all requisite surgical instruments & machines which are needed in the surgical management of these complex vitreoretinal disorders. Therefore, if you have ARMD, it is even more crucial that your children should regularly schedule eye examinations for ARMD, after 40 years of age. Vitamins, minerals and antioxidants may have a role in preventing the progression of macular degeneration. Hence, early diagnosis is the key to effective treatment because once vision is lost, it cannot be regained.
Experimental approaches like Retinal transplantation are still new and will require years of clinical research to determine their safety and effectiveness. Diabetes is a disease that occurs when the body does not secrete enough insulin or is unable to utilize it property causing sugar levels to increase.
The picture we see first forms in the retina and then transmitted to the brain, via the optic nerve.
Within the eye the damaged vessels may leak blood and fluid into the surrounding tissues and cause vision problems. An ophthalmologist can often diagnose serious retinopathy before you are pupil and looks inside the eye with an instruments called an indirect ophthalmoscope. In this test a dye is injected into the arm and photos of the eye are taken to detect where fluid is leaking.
The fragile new vessels may bleed into the vitreous, which is a clear, gel-like substance that fills the center of the eye.
Pressure in the eye builds up, resulting in neovascular glaucoma, a severe eye disease that causes damage to the optic nerve. Strict control of your blood sugar will significantly reduce the long-term risk of vision loss from diabetic retinopathy. The main goal of treatment is to prevent further loss of vision or in other words to stabilize existing vision. This treatment causes the abnormal fragile new vessels to shrink and often prevents them from growing in the future.
Laser surgery does not cure diabetic retinopathy and does not always prevent further loss of vision.
During vitrectomy, the retinal surgeon carefully removes blood and vitreous from the eye, and reattaches the retina to the back of the eye. More frequent medical eye examinations may be necessary depending on the stage and severity of the disease. Rather, it is a complex syndrome, which involves multiple systems and compensatory neurohumoral mechanisms.
On the other hand, they do point toward intrinsic changes in peripheral muscles [10, 11] and a neurohormonal interaction between the periphery and the heart [12]; furthermore, cardiac pump function is impaired, and all these interactions are determinant to the reduction of functional capacity in individuals suffering from heart failure. The continuous reoccurrence of these processes, even if initially beneficial, triggers a series of undesirable side effects, such as ventricular remodeling, which is characterized by alterations in the geometry and mechanical efficiency of the heart [13]. Chronic ß-adrenergic stimulation leads to an increase of proinflammatory cytokines, such as interleukin-1 and interleukin-6, to endothelin, and tumor necrosis factor-a (TNF-a) [16], which cause myocardial inflammation, an increase of nitric oxide synthesis, skeletal muscle myopathy, and activity of phosphatase protein 2A in the muscle, a regulator of muscle apoptosis [17,18] .
An ultrastructural morphometric analysis further revealed reduction in volume, mass, and surface of mitochondrial cristae. They were underwent 23 aerobic training programs and 6 muscular resistance training programs. Systolic volume may present slight increase [29] and improvement of cardiac debt and cardiac index have been attributed to the reversion of chronotropic incompetence and higher diastolic filling [30, 31, 32].
Reduction a sympathetic activity and changes in the renin-angiotensin axis cause smaller liberation of norepinephrine, improved RR variability and chronotropic response during effort [26, 34, 35]. The physical condition of the patients suffering from cardiac insufficiency is determined by the sum of primary myocardial injury and skeletal muscle abnormality, which resulted in the Muscle Hypothesis put forth by Clark et al. This may be influenced by changes in peripheral oxygen extraction and it has been demonstrated that the functional limitation in these patients may predominantly be due to the reduction of peripheral extraction of oxygen with a smaller participation of central factors [47,48].
There is an increase in sympathetic activity at rest and during physical training, elevation in heart rate, reduction in heart rate variability, and improvement in sympathetic vasoconstriction tonicity.
Consequently, there is a disproportionate increase of ventilation, and peripheral desaturation with diminished respiratory efficiency during effort may occur. This evaluation will allow for an individual customization of the different metabolic phases during physical effort. Another model used at InCor at FMUSP-HC recommends that the intensity for the physical activity be kept between 40% and 60% of the heart rate of O2 attained at peak effort, in the conventional ergometric test, or the average heart rate measured ventilatory threshold and less 10% of the one obtained at respiratory compensation point [57], when the cardiopulmonary effort test is chosen, even in the likelihood that the patient may be on medication which could interfere with chronotropism (Table 2, Pictures 4 and 5). Behavior of hemodynamic, ventilatory and metabolic variables observed every 15 seconds during cardiopulmonary test.
Note the drop of O2 and CO2 starting from the respiratory compensation point (RCP) or threshold 2, which indicates reduction in cardiac debt.
It presents itself reduced throughout the whole activity, with a drop after threshold 2, or respiratory compensation point (RCP). This is so due to the potential risks of angina, arterial hypotension, arrhythmias, or dyspnea. For stable patients non-supervised aerobic activity may be recommended for the remaining days, and should be controlled by the level of fatigue and training frequency previously established.
These benefits are mainly related to better vascular conductivity with partial recuperation of endothelial function [60], improved neurohumoral profile, and reduced inflammatory marker [61], which in turn result in a significant improvement of muscular oxidative capacity [50,62]. A = this group underwent a six-month, supervised physical training with na average reduction of 52% of high-sensitivity C-reactive protein (hs-CRP) concentration. According to a recent meta-analysis in which 801 patients were followed up for 2 years, there were clear benefits over morbimortality. However, there was no relationship between exercise and death in patients with heart failure during more than sixty thousand hours of exercise training, compared favorably with exercises in normal individuals and those with a heart condition [66]. Just as in the formal supervised program, home-based programs seem to be safe and effective in reducing symptoms and improving quality of life of patients with HF [71]. Some authors, such as Dubach et al [30], stand for high intensities, which aim at changing central hemodynamic parameters.
We have recently conducted a prospective randomized trial which included maximum functional capacity (peak O2) and submaximal (AT), peripheral muscle biopsy, neurohormonal measurement, autonomic balance and inflammatory markers, and a questionnaire pertaining to quality of life.
The vastus lateralis muscle biopsy revealed that in both training approaches there occurred an increase in oxidative capacity of the skeletal muscle, as well as an increase of peak VO2 equivalents [50]. Pictures 8 and 9 illustrate some of the improvements attributed to low intensity exercises. Via the central nervous system, they stimulate chemoreceptors of the ventilatory command, which results in the perpetuation of an inefficient ventilatory pattern. After a 12-week inspiratory muscle training, the authors demonstrated a boost in the order of 115% in maximum inspiratory pressure; Besides, there was an increase of 17% in peak O2, which resulted in a significant improvement of ventilatory response to exercise [76].
Patients suffering from HF frequently complain of erectile dysfunction, which hinders their quality of life.
A myriad of randomized trials verify that exercises have a positive effect on the different, important variables which guide the lives of HF patients; they improve their quality of life, enhance functional capacity, blood flow to metabolically active peripheral muscle and the endothelial-dependent vasodilation, reduce indirect action of sympathetic activity, foster the reduction of plasma norepinephrine levels at rest, and ameliorate myocardial demand of oxygen (heart rate x systolic arterial blood pressure) during physical activity.

ARMD affects the macula, the central part of the retina responsible for vision needed for daily activities like reading or driving. Several studies have identified possible additional risk factors like age, genetics, hypertension, sun exposure, farsightedness, light skin or eye color. In macular ischemia, blood supply to this crucial zone is affected and often causes permanent drop in vision which may not respond to laser. If the vitreous hemorrhage is small, a person might see only a few black spots called “floaters”. The prognosis for visual recovery is dependent on the severity and duration of the detachment. Newer anti-VEGF injection (Avastin, Macugen, Lucentis) are also being used now with lesser side-effects and promising results. The peripheral manifestations of the disease, such as endothelial dysfunction, skeletal muscle changes, abnormal blood flow, and the chemoreflex control of breathing [1,2], are the best elements to determine the symptoms which generate effort intolerance. These symptoms are due to a complex physiopathological response to ventricular dysfunction and ensuing reduction of oxygen delivery to tissue.
Further, there occur changes in gene expression, progressive apoptosis, and worsening of myocardial function [14].
On the other hand, the actual cause of structural, metabolic, and functional damage to the muscle as a whole remains unknown. Reduction in the activity of cytochrome c oxidase, creatine kinase (CK), and other oxidant enzymes in this organelle have been detected through histochemical analysis [19, 20]. The analysis of the results verified improvements in HRQoL, VO2max, distance on the 6-minute walk test, work capacity measured in Watts, and duration of physical activity [27].
A reduction in peripheral vascular resistance, associated to endothelial dysfunction correction, attenuates cardiovascular remodeling and enhances muscular blood flow [36, 37]. Numerous research studies were published in the last decade and they demonstrated that effort limitation on heart failure patients is related to qualitative and quantitative changes in skeletal muscle, which may have reasonable reversibility through regular physical activity [49, 50]. Continuous physical activity leads to an increase in parasympathetic activity, characterized by lower heart rate at rest and during submaximal exercises [51]. A study recently conducted by Roveda et al [48] demonstrated muscle nerve sympathetic activity, measured directly from the peroneal nerve, increases progressively from the healthy individual to the patient with left ventricular dysfunction, and from those to the ones who presented advanced heart failure, with a reduction of renal and muscle blood flow. These physiopathological changes facilitate vasoconstriction and expansion of plasma volume, thus contributing to preserve cardiac debt and systemic arterial blood pressure and reducing vasodilation capacity.
Regular physical activity, with the inclusion of breathing exercises, helps equalize ventilatory parameters, improving dyspnea and favorably influencing effort tolerance. That way it is possible to optimize an individual determination of ventilatory thresholds, from which the metabolic and hemodynamic quantification of physical activities for these patients will be established. In table 1 there is a physical training scheme for patients suffering from heart failure at the Dante Pazzanese Institute of Cardiology. Exercise prescription must be limited to threshold 1, or anaerobic threshold (AT), well before the area in which systolic volume decreases. Trained professionals and emergency equipment for cardiorespiratory resuscitation must be easily accessible. The duration of the exercise must be gradually increased according to the patient’s tolerance. Picture 6 illustrates the reduction of the inflammatory marker, high-sensitivity C-reactive protein (hs-CRP), through supervised physical training for six months.
The authors concluded that the number needed to treat was that of 17 patients undergoing physical training to prevent one death in two years [64].
As for BNP, its secretion is related to the distention of the ventricular wall, and low intensity training could promote lesser parietal tension in the left ventricle and consequently reduce the discharge of BNP into the blood flow. A randomized trial published by Belardinelli et al submitted 59 male patients to a supervised aerobic physical training program.
Besides, there are other probable effects, such as the increase of cardiac debt due to augmented heart rate and peak systolic volume [78], and improved ejection fraction at rest.
These, if present, may need to be prophylactically treated( strengthened )with laser photocoagulation to reduce the risk of complications like retinal detachment. Cardiac debt and augmented systemic vascular resistance (SVR) stimulate the sympathetic nervous system. Krankel et al [18] recently identified 24 regulatory genes of skeletal muscle dysfunction in an experimental model in rats with induced heart failure. These alterations, similar to those observed in physical deconditioning due to inactivity, compromise cellular respiration and lead to early anaerobic metabolism during exercise. Chronic physical activity seems to reduce the levels of angiotensin II, aldosterone, vasopressin, and natriuretic peptides [52]. The dyspnea observed in patients in a less severe state, without edema, has been more clearly associated to lack of physical activity and metabolic abnormalities of locomotor skeletal muscle than pulmonary congestion [46]. Should ergospirometry not be available, an ergonomic test with progressive and continuous loads should be conducted, and only interrupted in the event of signs or symptoms [54,55,56]. Endurance and resistance training might be optionally be applied along with aerobic training, ideally in the initial weeks.
Based on this date, our physical activity prescriptions take into account the heart rate during training and limited by AT, that is, exercises whose intensities are below the area of metabolic acidosis. Likewise, resistance training leads to growth in size and number of mitochondria, growth in myosin heavy chain percentage in type 1 fibers and improvement in muscle strength and mass [79]. The Insert measures 6 inches wide and 28 inches long, and has a 6 x 9 3 inch vinyl covered pad.
Other changes include an increase in cardiac frequency, energy consumption of the myocardium, systemic vasoconstriction, and activation of the renin-angiotensin-aldosterone system (RAAS).
The increase in carbon dioxide (CO2) production resulting from metabolic acidosis stimulates respiratory control centers and they, in turn, increase minute ventilation (VE); this results in dyspnea, muscular fatigue, and effort intolerance [21, 22].
In 1990, Coats e cols [26] observed improvement in both aerobic power and heart failure symptoms with the regular practice of exercises, thus putting in check the recommendation that patients should rest as part of the treatment of the illness. This yields excellent results, such as improved flexibility, muscle trophism, and muscle mass, notably in patients with sarcopenia [58]. This corresponds to 67% of peak VO2, before the beginning of metabolic acidosis, as shown in picture 7.
The study revealed improvement in sexual dysfunction as measured by the sexual performance score (SAP questionnaire) and the increase of 18% in peak O2. Angiotensin II and aldosterone act upon cardiovascular remodeling and arterial flexibility [15]. On the other hand, physical activity restores vasodilation capacity in patients who suffer from heart failure, which in turn improves endothelial synthesis of nitric oxide. The benefits were associated to the systemic effect of physical activity on endothelial dysfunction with direct impact on the quality of penile erection [77]. This vasodilating effect is not limited to the limb trained and its benefits last systemically for an average of up to six months after the end of the training program [45]. The constant monitoring of blood pressure and heart rate with the aid of a heart rate monitor is advisable.
Accordingly, regular physical training brings confirmed benefits with favorable systemic repercussions and must become part of the clinical treatment of patients with stable CHF and using optimized medication. These morphofunctional changes interfere with the reduction of exercise tolerance and reduction of O2 at peak of effort and anaerobic threshold [49] (Picture 2). Just as the clinical treatment yields evident central benefits, physical exercise promotes favorable peripheral adaptations, resulting in improved functional capacity and quality of life for these patients. Regular physical activity improves mitochondrial oxidating capacity which reverts, at least partially, the abnormalities in skeletal muscle fiber [50] (Picture 3). Picture 10 illustrates the flow chart of evaluations and procedures for the recommendation of rehabilitation in HF.
