Beltina.org The Eyes Exophthalmos - bulging outward of the eyeExophthalmos - bulging outward of the eyeExophthalmos - bulging outward of the EYE, sometimes called poptosis. Exophthalmos can cause significant and permanent vision impairment, and requires prompt treatment. The diagnostic path begins with an OPHTHALMOLOGIC EXAMINATION and blood tests to assess thyroid function. Today I found out what makes your eyes red in flash photographs.  Simply put, that crazy zombie look people tend to get, as if they are about to use you as a pre-lunch snack, has to do with how light from a camera flash reflects off the eye, and the specific wavelengths at which it tends to do this. It is important to note that the term “light” can refer to any electromagnetic radiation, not just the radiation in the visible spectrum. Other factors contributing to the red-eye effect is the amount of melanin in the layers behind the retina, and the age of the person being photographed.  Light skinned people with blue eyes tend to have less melanin in the fundus. Children will also tend to get a red-eye effect more readily then do their adult counterparts.  This is because a child’s pupil will dilate faster than adults, in low light situations. The frequency of electromagnetic radiation that can be seen in the visible spectrum ranges from 400 nanometers (nm) to approx. Due to the Tapetum Lucidum ability to increase the intensity of available light, this tissue layer provides certain animals the ability to see in much dimmer light.  This is obviously quite useful to nocturnal carnivores who hunt at night, or fish at depths  where light is scarce. Hunters have been known to use Eyeshine to locate their prey.  The technique is called “spotlighting”. In the Movie Blade Runner, the red-eye effect was intentionally induced to indicate which characters were “replicants” or artificial life forms. In a photograph of a child’s face, red-eye in one eye but not the other may be a sign of the cancer Retinoblastoma.

A child with left sided eyelid erythema, swelling and proptosis following a bout of upper respiratory infection.3.
A 25-year-old male with bilateral eyelid swelling, proptosis and painful diplopia was found to have evidence of bilateral orbital pseudotumor and treated with systemic corticosteroids after imaging studies failed to show evidence of any infectious cause of his symptoms.4. External photographs of a young male child who suffered trauma over his right brow area after which he developed orbital cellulitis and formation of an abscess that required drainage. Anterior and sagittal view of the frontal, ehtmoidal, sphenoid and maxillary sinuses and their close relationship with orbital anatomy.



External photograph of a 42-years-old female who presented with left-sided orbital cellulitis and abscess formation due to the acute over chronic dacryocystitis. External photograph of a 19-years-old male who presented with 3 day history of left-sided facial erythema, swelling, conjunctival chemosis, proptosis and eruptive skin lesions.
External photographs as well as CT-scan (axial and coronal views) of a 7-year-old boy who presented with upper respiratory infection followed by painful diplopia, left eye proptosis and decreased vision. External photograph of an 8-year-old boy who required drainage of his right orbital abscess after failing 3 days of by systemic antibiotic treatment. Lateral view of the schematic drawing showing extensive venous drainage of the facial structures along with orbital veins and their direct connections with cavernous sinus. Most exophthalmos results from Graves’s disease and is a classic symptom of this form of HYPERTHYROIDISM. When Graves’s disease or hyperthyroidism is the cause, treatment to restore appropriate levels of thyroid hormones often though not always returns the eye to its normal position. Electromagnetic radiation can be classified into seven types; Gamma, X-ray, Ultraviolet, Visible, Infrared, Microwave and Radio wave. A diagnosis of Herpes Zoster Ophthalmicus was made and patient was treated for acute Zoster infection and its complications. CT-scan (axial and saggital cuts) showed an evidence of maxillary sinusitis and an abscess formation in the superior orbit.11. She had complete loss of vision in the right eye which was attributed to central retinal artery occlusion due to orbital infectious process.

Thyroidrelated exophthalmos results from swelling of the tissues around the eye and within the orbit that develops in reaction to the high levels of thyroid HORMONE present in the circulation. Persistent exophthalmos may prevent the eyelids from closing over the eye, exposing the CORNEA to excessive dryness and potential trauma. This patient required drainage of his orbital abscess which resulted in immediate resolution of his symptoms.7. IntroductionOrbital cellulites is an uncommon infectious process in which patient may present with pain, reduced visual acuity, compromised ocular motility and significant proptosis. Other causes of exophthalmos include ORBITAL CELLULITIS, the autoimmune disorder Wegener’s granulomatosis, and FRACTURE of the facial or orbital bones that push the eye out of place. Less common causes of exophthalmos include tumors of the eye, OPTIC NERVE, or BRAIN that protrude into the orbital socket and ANEURYSM (ballooning of the arterial wall) of the internal carotid ARTERY, a branch of which runs behind the eye. In the vast majority of cases, a history of upper respiratory tract infection prior to the onset is very common especially in children. Exophthalmos can affect one eye (unilateral) or both eyes (bilateral), and when bilateral can affect one eye more prominently than the other.


In addition to the loss of vision, orbital cellulitis can be associated with a number of other serious complications that may include intracranial complications in the form of cavernous sinus thrombosis, meningitis, frontal abscess and even death.
Historically, since the wide spread use of effective antibiotics, the serious complications of orbital cellulitis have become much less frequent.
For example, Connel et al, [3] reported case of a 69-year-old man who presented with no light perception vision, proptosis and significant ophthalmoplegia. In their case, despite emergent drainage of the abscess and systemic antibiotics, no improvement in vision was noted despite the return of the full ocular motility and disappearance of proptosis. Connel et al, [3] postulated Streptococcal-related ischemic necrosis of the optic nerve as a possible mechanism of loss of vision in their patient. In one of the recent survey of 52 patients treated for orbital cellulitis, over 35% had decreased vision and on their last follow-up, only 4% had decreased visual acuity. Further, there were 9 cases of intracranial orbital abscess extension that required either extended treatment with systemic antibiotics alone or in combination with neurosurgical intervention.
Patient presentationPatients with orbital cellulitis may present with signs of eyelid swelling, conjunctival chemosis, diplopia and proptosis which may not be prominent in cases of preseptal cellulitis. Many of these patients come with local symptoms in the form of eyelid edema, redness, chemosis, decreased ocular motility and proptosis (Figure 1).
Patients having superficial signs of swelling (preseptal cellulitis) should be differentiated from deeper infection resulting in orbital cellulitis, in which case, signs and symptoms resulting from inflammation may be helpful. In cases of the optic nerve involvement, disc edema or neuritis with rapidly progressing atrophy resulting in blindness may occur.
Mechanical pressure on the optic nerve and possibly compression of the central retinal and other feeding arteries results in optic nerve atrophy. Inflammation may result in septic uveitis, iridocyclitis or choroiditis with a cloudiness of the vitreous, including septic pan ophthalmitis.
A less common complication of orbital cellulitis is glaucoma that can cause decreased vision, reduced visual field or even enlarged blind spot on presentation. Differential diagnosisSome of the differential diagnosis for patients presenting with orbital cellulitis may include, allergic reaction to topical or systemic medication, edema from hypo-proteinemia due to variety of systemic causes, orbital wall infarction and subperiosteal hematoma due to unrecognized trauma or due to blood coagulation disorders. Differential diagnosis may also include orbital pseudotumor (Figure 2), retinoblastoma, metastatic carcinoma and unilateral or bilateral exophthalmos secondary to thyroid related orbitopathy. Most common predisposing factors for orbital cellulitisIn the most reported series, the most common predisposing factor for orbital cellulitis is sinus disease, especially in children. It can originate from face or eyelids after a recent or past trauma, dental abscess or from a distant source by hematogenous spread.
