Choroideremia is a genetic condition characterized by progressive vision loss that mainly affects males. Signs and symptoms of this condition include night blindness, progressive narrowing of the field of vision (tunnel vision), and a decrease in the ability to see details (visual acuity). These vision problems are due to an ongoing loss of cells in the retina and choroid. The vision impairments get progressively worse and usually lead to blindness typically in late adulthood. Choroideremia is caused by mutations in the CHM gene and is inherited in an X-linked recessive pattern.[1]
