What is AMD?Age-related Macular degeneration (AMD) is the leading cause of visual impairment and blindness in persons over 50 years of age.
AMD is often bilateral and causes central distortion (metamorphopsia) and loss of central visual acuity.
They are deposits within the bruch's membrane and cause a small elevation in the Bruch's membrane. Changes in the PRE layer include hyperpigmentation and pigment clumping as shown in this picture, and hypopigmentation or atrophy. Neovascular vessels often cause leakage of fluid and hemorrhage into the subretinal space, which in turn lead to a sudden decrease in central vision. Although only about 15% of patients with AMD develop the neovascular disease, it is responsible for 85% of visual loss in all patients with AMD. Severe forms of AMD cause a decrease in central vision but usually do not affect the peripheral vision.
Development of neovascularization causes a sudden decrease in central vision with development of metamorphopsia. The risk of developing either wet AMD or geographic atrophy leading to loss of central vision is dependent of the pre-existing severity of dry AMD.
Smoking Increases the risk of AMDSeveral large population based studies have documented an increased risk of all forms of AMD in smokers compared to non-smokers.
Diet and macular DegenerationObservational studies have suggested that a high intake of carotenoids lutein and zeaxanthin, found mainly in green leafy vegetables, may be associated with a lower risk of neovascular AMD. When an elderly person, or someone with high degree myopia develops a gradual decrease in their central vision, they may have a problem with the macula – one of the problems is a macular hole. A macular hole occurs when there is a tear in the macula, the central part of the retina that is responsible for processing detailed images (Find out how the eye works). Some symptoms of a macula hole include a gradual worsening of central vision or visual distortion (seeing straight lines as wavy).
Macular holes may be treated with a vitrectomy, a form of keyhole surgery that uses small probes to enter inside the eye to remove the vitreous. Macular pucker: Scar tissue in the macula, the area of the retina responsible for sharp central vision. Maculopapular rash is a type of skin disorder which causes certain parts of the skin to turn red. The appearance of maculopapular rash is quite similar to skin disorders that are caused due to certain diseases such as measles, syphilis and scarlet fever as well as other skin eruptions caused due to heat rashes. Most cases of maculopapular rash are red in color which may subsequently change into different colors as the condition progresses into the later stages. Individuals affected by scarlet fever develop maculopapular rash a day or two after the appearance of the fever.
It is caused due to body lice and is characterized by high fever and appearance of maculopapular rash. Syphilis: This infectious and chronic disease leads to the development of maculopapular rash ulcers.
HIV-1 disease: It results in AIDS and also causes the development of maculopapular rash, which is why the condition is often referred to as HIV rashes. Epstein-Barr virus: In addition to maculopapular rash, the virus also results in the onset of painful blisters as well as certain cancers that can be found in people living in China or the African continent. Scabies: The maculopapular rash that results from this skin condition causes severe itching and irritation.

Chikungunya: This viral disease is caused by mosquitoes and results in high body temperature as well as the development of maculopapular rash.
Certain drugs: Maculopapular rash can also be caused as a side effect of certain medications such cefoperazone sodium, amoxicillin, cefobid and other antibiotics. Maculopapular rash caused due to Marburg hemorrhagic fever requires specialist medical treatment. Rashes caused due to the Epstein-Barr virus are treated with painkillers, rest and the intake of fluids.

Geographic atrophy may progress slowly, and if it involves the center of macula central vision is lost.
However dry AMD is only responsible for 15% of severe visual loss in all patients with AMD. Patient should know that even with advanced dry AMD or wet AMD they will most likely not go blind.
As discussed earlier effective treatments exist for choroidal neovascularization which include injection of anti-angiofenic medications. The prevalence of AMD is estimated to be about 10% at age 50 and dramatically increases to about 30% at age 75.Race and EthnicitySevere AMD including neovascular disease is less common in black and Hispanic populations compared to the non-hispanic white population. Unlike age and race, smoking is a modifiable risk factor, and cassation of smoking should be part of the management of AMD.Light ExposureSeveral studies have shown conflicting results regarding a possible association between sunlight exposure and AMD. Diets rich in Omega3 fatty acids found in fish, may also reduce the risk of neovascular AMD. Specific findings which may indicate choroidal neovascularization include: subretinal fluid, retinal thickening or edema with loss of foveal depression, elevation of the retinal pigment epithelial layer or RPE detachment. A gas is then injected into the eye to replace the vitreous and prevent it from pulling on the retina. Some individuals may develop the skin condition on the trunk while others may develop it on their faces. In addition to the rash, the affected individual may also develop high fever with body temperatures that can touch 104 degree Fahrenheit.
It is a dangerous type of fever and is known to result in fatality of about 25 percent of the patients. The Type 1 Human Immunodeficiency Virus is one of the most dreaded causes of maculopapular rash. This tropical and highly infectious disease is spread by mosquitoes and results in joint pain, headaches as well as skin rashes.
Hence treating the various conditions and diseases associated with it can result in an effective cure.
Though there are no specific methods to cure the condition, studies indicate that the causative virus can be destroyed by gamma radiation and ultraviolet radiation. However, it is important to immediately consult your health care provider if you notice red spots on your skin.
Please contact your health care provider for specialized medical advice, diagnosis and treatment. Formation of CNVM involves abnormal growth of blood vessels from the choriocapillaris through the Bruch’s membrane and the RPE layer into the subretinal space.

Decrease in central vision presents itself as distortion and overtime a central blind spot will develop. Unlike wet AMD, geographic atrophy is not treated with intravitreal injections of anti-angiogenic medications such as Lucentis or Avastin.
Your eye doctor will administer eye drops to enlarge the pupils temporarily so that he or she can check the back of your eyes (the retina) for holes. Following surgery, the patient will need to lie in a face-down position for one to two weeks to allow the gas bubble to press against the macula and seal the hole.
Macular pucker is due most often to age-related shrinkage of the vitreous which pulls away from the retina, causing the retina to scar and wrinkle. Individuals affected by the condition may suffer from the development of both macules and papules on their skin. The skin areas affected by maculopapular rash peel after some time and their healing can take a few weeks. There is no sign of abnormal blood vessels in dry AMD, including no fluid or blood under the retina.
Many patients however continue to perform their activities of daily living using their peripheral vision and will continue to read larger print with the use of visual aids such as magnifiers.Two different forms of AMD may be responsible for central visual loss in AMD. Currently the only effective treatment for geographic atrophy is prevention using the AREDS vitamins, diet and possibly Leutin and Omega 3 fatty acids.
The eyes are also painlessly scanned with optical coherence tomography (a light used to check the different layers of the retina) to evaluate the macula. Other causes of macular pucker include trauma (from surgery or an eye injury), retinal detachment, inflammation, and problems with the retinal blood vessels. Maculopapular rashes have a red appearance in the initial stages of measles and then gradually turn brown in color during the later stages. At the severe end of the spectrum are changes that cause loss of central vision and distortion.
A person with soft drusen in both eyes and pigmentary changes in one eye has 3 risk factors. Another cause of macular hole is high myopia, where the elongation of the eyeball puts stress on the macula, causing it to break. The success of improving the vision varies from person to person and ranges from 60 to 80 per cent. The only treatment is surgery which consists of a vitrectomy (removal of the vitreous) combined with peeling away of the scar tissue.
AMD generally does not cause total blindness and patients will keep their peripheral vision even in the more severe cases. Most patients recover about half of their lost vision, and distortion is significantly reduced.
The most common complication of vitrectomy is an increase in the rate of cataract development.
Also called epiretinal membrane, retinal wrinkling, premacular fibrosis, and cellophane maculopathy.
