Clinical peculiarities in challenging cases of atypical retinitis pigmentosa: a case series and review of the literature

Abstract

We report three distinct cases who presented initially as age-related macular degeneration, intermediate uveitis, and cystoid macular edema respectively. They were later diagnosed to have atypical retinitis pigmentosa. Clinical presentation, full field perimetry, fundus photography, electroretinography, fundus fluorescein angiography and optical coherence tomography are described in detail for all three patients. The course of their disease and treatment during the period of observation are discussed with complete photo-documentation. Since the fundus may appear clinically normal in such cases, the diagnosis may be missed. So, these cases pose a diagnostic challenge to the ophthalmologist.
