Classification

Retinitis Pigmentosa

Classification	Clinical Manifestations
Nyctalopia	Occurs early on during the clinical course of Retinitis Pigmentosa. Night blindness occurs due to the loss of rod function. Nyctalopia can be an indicator of the eventually clinical severity of the complications associated with retinitis. Early onset of severe complications typically indicates more severe complications later on during the clinical course.
Fundus	Defective rod cell response, although fundus appears normal Arteriolar narrowing Intraretinal pigmentation Loss of pigment in pigment epithelium Intraretinal clumping due to the accumulation of melanin
Visual acuity	Macular lesions Defective cone cell function Loss of central acuity
