Abstract

Retinitis pigmentosa can be associated with exudative vasculopathy in rare instances, which can manifest as retinal vasoproliferative tumours. We present the case of a 33-year-old woman previously diagnosed with retinitis pigmentosa sine pigmentosa in both eyes. She was asymptomatic and just came in for a routine follow-up eye examination. Thorough examination of the peripheral retina on the right eye revealed a dome-shaped retinal tumour with a feeder vessel and surrounding exudative changes at the superotemporal periphery, consistent with a secondary retinal vasoproliferative tumour from retinitis pigmentosa. She subsequently underwent focal laser photocoagulation of the tumour which resulted in tumour stabilisation. While exudative vasculopathy is very uncommon in retinitis pigmentosa, ophthalmologists need to be aware of its occurrence in such patients. Vision loss may occur from exudation, haemorrhage, retinal detachment and neovascularisation. A thorough examination of the peripheral retina is warranted in these cases.
