Diagnosed illness Congenital stationary night blindness (CSNB)
Clinical information X-linked congenital stationary night blindness is a retinal disorder mainly characterized by reduced vision during twilight and night time. Additionally, it can also present with reduced visual acuity, high myopia, nystagmus, and strabismus. Color vision is typically not affected. The vision problems associated with this condition are congenital. The symptoms tend to remain stable (stationary) over time. There have been two major types of X-linked congenital stationary night blindness identified: complete and incomplete form, which differ in their genetic cause and their symptoms.
