Definitions for choroideremia
This page provides all possible meanings and translations of the word choroideremia
Choroideremia is an X-linked recessive retinal degenerative disease that leads to the degeneration of the choriocapillaris, the retinal pigment epithelium, and the photoreceptor of the eye. Choroideremia is a rare inherited disorder that causes progressive loss of vision due to degeneration of the choroid and retina. It occurs almost exclusively in males. In childhood, night blindness is the most common first symptom. As the disease progresses, there is loss of vision, frequently starting as an irregular ring that gradually expands both in toward central vision and out toward the extreme periphery. Progression of the disease continues throughout the individual's life. Both the rate of change and the degree of visual loss are variable among those affected, even within the same family. The actual vision loss is caused by degeneration of several layers of cells that are essential to sight. These layers, which line the inside of the back of the eye, are called the choroid, the retinal pigment epithelium, and the retina. The choroid is a network of blood vessels located between the retina and the sclera, the "white of the eye." Choroidal vessels provide oxygen and nutrients to both the RPE and the retina's photoreceptor cells.
U.S. National Library of Medicine
