Retinitis pigmentosa.
Retinitis pigmentosa is a subset of inherited diseases associated with progressive degeneration of the retina otherwise classified as retinal dystrophies. Clinically, patients have nyctalopia (night blindness), progressive visual field loss, and eventually loss of central vision. Patients with retinitis pigmentosa should be evaluated for other ocular conditions that may simulate the condition, as well as for systemic disorders.
