Abstract

We report a case of binocular retinitis pigmentosa (RP) with completely different visual acuity between 2 eyes, which may be contributed by the presence of cilioretinal arteries (CRAs) in 1 eye. A 66-year-old female patient complained of blurred vision after binocular cataract surgeries. Examinations revealed her right eye had 20/25 central visual acuity, but the fellow eye only had light perception. Subsequent fundus photography of both eyes firmed the diagnosis of binocular RP. However, there were some significant differences in retinal vessels, which were attenuated in her left eye in contrast to several spared retinal arterioles in the right eye. Optical coherence tomography angiography showed that the spared vessels might be CRAs. Our case provides an evidence that macular blood flow may contribute to the survival of cone cells in RP.
