Symptoms And Causes Of Abetalipoproteinemia

Retinitis Pigmentosa

Retinitis pigmentosa is an eye condition that is typical among patients with abetalipoproteinemia, and it can be triggered by deficiencies in vitamins A and E. This eye disorder affects the retina, the part of the eye that receives light. For patients with retinitis pigmentosa, retinal cells slowly deteriorate, resulting in a progressive loss of vision. One of the first symptoms of this eye condition is nighttime vision loss, and this is typically noticeable in childhood. As the disorder advances, patients start to have blind spots in their peripheral vision, and this eventually produces tunnel vision. Over the course of years or decades, central vision is also impacted, making it difficult to perform daily tasks such as writing, reading, and driving. Some patients may also have difficulty with facial recognition. The majority of patients with retinitis pigmentosa become legally blind by the time they are adults. Optical aids, retinal prostheses, and some surgical interventions may be useful for patients with this condition.
