The oculomotor manifestations tend to improve with age but the syndrome may also be associated with learning and speech difficulties, or, in some cases, cerebral malformations. Both sporadic and familial forms have been described, with sporadic forms being more frequent. The mode of transmission of the familial form has not yet been clearly established. A gene located on the long arm of chromosome 2, near to the NPHP1 gene involved in nephronophthisis, may be associated with ocular motor apraxia, Cogan type."

Pure reds cannot be seen, instead appearing black; purple colors cannot be distinguished from blues; more orange-tinted reds may appear as very dim yellows, and all orange-yellow-green shades of too long a wavelength to stimulate the blue receptors appear as a similar yellow hue. It is hereditary, sex-linked, and present in 1% of males."

        "definition": "Pigment-dispersion syndrome is an eye disorder that occurs when pigment granules that normally adhere to the back of the iris (the colored part of the eye) flake off into the clear fluid produced by the eye (aqueous humor). These pigment granules may flow towards the drainage canals of the eye, slowly clogging them and raising the pressure within the eye (intraocular pressure or IOP). This rise in eye pressure can cause damage to the optic nerve (the nerve in the back of the eye that carries visual images to the brain). If the optic nerve becomes damaged, pigment-dispersion syndrome becomes pigmentary glaucoma. This happens in about 30% of cases. Pigment-dispersion syndrome commonly presents between the second and fourth decades, which is earlier than other types of glaucoma. While men and women are affected in equal numbers, men develop pigmentary glaucoma up to 3 times more often than women. Myopia (nearsightedness) appears to be an important risk factor in the development of pigment-dispersion syndrome and is present in up to 80% of affected individuals. The condition may be sporadic or follow an autosomal dominant pattern of inheritance with reduced penetrance. At least one gene locus on chromosome 7 has been identified. Pigment-dispersion syndrome can be treated with eye drops or other medications. In some cases, laser surgery may be performed."

        "definition": "Acute zonal occult outer retinopathy (AZOOR) is a rare condition that affects the eyes. People with this condition may experience a sudden onset of photopsia (the presence of perceived flashes of light) and an area of partial vision loss (a blindspot). Other symptoms may include 'whitening of vision' or blurred vision. Although anyone can be affected, the condition is most commonly diagnosed in young women (average age 36.7 years). The underlying cause of AZOOR is currently unknown; however, some researchers have proposed that infectious agents (such as viruses) or autoimmunity may play a role in the development of the condition. No treatment has been proven to improve the visual outcome of AZOOR; however, systemic corticosteroids are the most commonly used therapy."

Additional symptoms may include fatigue, tinnitus, or depersonalization and depression. Most people have normal vision tests and normal brain images. Standard migraine treatments are often not helpful. There is no cure or effective treatment to completely relieve the symptoms, but medication seems to help some people with visual snow."

Attacks associated with VKC are common in the spring (hence the name 'vernal') and summer but often reoccur in the winter. Signs and symptoms usually begin before 10 years of age and may include hard, cobblestone-like bumps (papillae) on the upper eyelid; sensitivity to light; redness; sticky mucus discharge; andinvoluntary blinking or spasms of the eyelid (blepharospasm).The condition usually subsides at the onset of puberty. It is caused by ahypersensitivity (allergic reaction)to airborne-allergens. Management focuses on preventing 'flare ups' and relieving the symptoms of the condition."
