Abstract

The Retinitis Pigmentosa Sine Pigmento is a subtype of atypical retinitis pigmentosa (RP) characterized by the absence of pigment deposits. When the characteristic peripheral bone-like spicule pigmentary changes are present, diagnosis of RP is straightforward. But in RP Sine Pigmento, fundus examination may be unremarkable as the characteristic pigmented epitheliopathy is not seen, and the diagnosis may be missed, particularly during the early stages of the disease, when clinical features suggestive of RP are usually not yet present. We describe a patient who was diagnosed with Retinitis Pigmentosa Sine Pigmento with the help of multimodal imaging on a routine retina examination. A 21 years old male presented to us for a routine eye checkup. Fundus examination revealed RPE mottling in peripheral retina with normal optic disc and macula. Retinal multimodal imaging (OCT & FAF) were used to diagnose RP Sine Pigmento which was later confirmed by electroretinogram.
