Guide To Diagnosing And Treating Leber Congenital Amaurosis

Reduction In Light Exposure

It is recommended for Leber congenital amaurosis patients to reduce light exposure to their eyes to prevent photophobia or light sensitivity. Individuals with LCA often feel discomfort with sources of incandescent light, sunlight, and fluorescent light. These individuals tend to squint or close their eyes when too much light is present. Often, patients also make a habit of rubbing, pressing, and poking their eyes. Bright light often causes Leber congenital amaurosis patients to develop severe migraines frequently. These individuals are instructed to avoid the sun and any other bright sources of light, even if they are indoors. Specialized sunglasses with extreme ultraviolet protection and strong polarization can help an individual reduce their eye exposure to light. An individual affected by LCA may benefit from eyeglasses containing sensitive photochromic lenses or lenses that are clear in low lighting conditions that become darker automatically in bright lighting conditions. In cases where photophobia is severe, the patient may consider the use of prosthetic contact lenses. These contact lenses decrease the quantity of light allowed to enter into the individual's eye.
