Progressive cone–rod dystrophy

Abstract

Inherited macular dystrophies present with varying clinical signs. They possess significant overlap with other inherited retinal dystrophies and with several acquired retinal degenerations. A classification system for diagnostic purposes is crucial. This paper includes a case report of an extremely unusual presentation of a cone–rod dystrophy. Its challenge lies in the difficulty to differentiate it from not only inherited dystrophies of the photoreceptors and retinal pigment epithelium, but also from acquired degenerations of the macula and retina. This paper reviews the differential diagnoses and management considerations of cone–rod dystrophy.
