Abetalipoproteinemia eyewiki

Many of the signs and symptoms of Abetalipoproteinemia result from a severe vitamin deficiency, especially vitamin E deficiency, which typically results in eye problems with degeneration of the spinocerebellar and dorsal column tracts Posterior pole of patient with abetalipoproteinemia showing pale optic nerve head, attenuated blood vessels and atrophic retina (left). Midperipheral bony spicule pigmentary changes in same patient (right). (Courtesy of Dr. W. R. Green Xerophthalmia refers to the spectrum of ocular disease caused by severe Vitamin A deficiency (VAD). Vitamin A serves several essential functions in the eye, and deficiency can lead to a constellation of ocular signs and symptoms that affect the conjunctiva, cornea, and retina

The ophthalmologist's role in the management and diagnosis of genetic disorders can be critical for patients, families and referring providers in the steadily advancing field of genetics. Genetic testing can be a useful medical tool in ophthalmology to help confirm or rule out a suspected inherited ocular disorder, provide important information of inheritance patterns and risk of recurrences. Disease Entity Oculomotor apraxia (OMA) was first described in 1953 by American Ophthalmologist David Glendenning Cogan as a defect in, or absence of, the ability to perform voluntary eye movements. Affected patients are unable to willingly draw their eyes to an object that grabs their attention but can otherwise freely gaze left and right Angioid streaks are bilateral, narrow, irregular lines deep to the retina configured in a radiating fashion emanating from the optic disc, which result from breaks in a weakened Bruch's membrane. Ophthalmologists should be aware that there are numerous systemic diseases associated with angioid streaks, the most common being pseudoxanthoma elasticum.  The diagnosis of angioid streaks is. In patients with hereditary abetalipoproteinemia (Bassen-Kornzweig syndrome), mutations in the gene encoding a microsomal triglyceride transfer protein lead to depletion of vitamin A in the liver and the retina. A low-fat diet and supplementation of fat-soluble vitamins A, E, and K are recommended

Leber congenital amaurosis (LCA) is a family of congenital retinal dystrophies that results in severe vision loss at an early age. Patients present usually with nystagmus, sluggish or near-absent pupillary responses, severely decreased visual acuity, photophobia and high hyperopia. It is the most severe retinal dystrophy causing blindness by. See the treat­ment regimens in Table 1. Improvement of Bitot's spots is seen within 2 weeks of high-dose vitamin A therapy. However, the retinal mani­festations of vitamin A deficiency are slower to respond to treatment, with night blindness and dark adaptation problems often persisting for 4 weeks. 12. 1 Sharma A at al. Int J Prev Med. Retinitis pigmentosa (RP) is a genetic disorder of the eyes that causes loss of vision. Symptoms include trouble seeing at night and decreased peripheral vision (side vision). As peripheral vision worsens, people may experience tunnel vision.Complete blindness is uncommon. Onset of symptoms is generally gradual and often in childhood The primary goal of frontalis suspension techniques in ptosis management is to improve visual function by elevating the eyelid. A secondary goal is to improve facial aesthetics and symmetry

Neuropathy ataxia retinitis pigmentosa (NARP) syndrome is characterized by a variety of signs and symptoms that mainly affect the nervous system. Beginning in childhood or early adulthood, most people with NARP experience numbness, tingling, or pain in the arms and legs (sensory neuropathy); muscle weakness; and problems with balance and coordination () Cogan type ocular motor apraxia is a rare congenital disorder characterized by a defect in side-to-side (horizontal) eye movements. The eyes do not move properly in response to stimuli or voluntarily. When affected infants are asked to fixate on an object to the side, their eyes will lag and then move in the opposite direction
