A 67 year-old woman with diabetes mellitus type 2 no medical background of interest was attended in hospital due to visual loss of left eye of 4 months of onset. The fundus examination revealed findings corresponding to moderate non-proliferative diabetic retinopathy in the right eye and pigmented lesions similar to bone spicules and atrophy of the retinal pigment epithelium in the middle periphery and in the macular area in the left eye. The full-field electroretinogram was flat, with a slight insinuation of the b-wave in the light adaptation with a single flash of 3.0cd in the left eye. The optical coherence tomography showed the atrophic retina in all its layers, as well as intraretinal cysts and a serous neurosensory detachment of the macular retina with a lesion of high reflectivity in the left eye. Infectious and inflammatory diseases were ruled out. Three doses of intravitreal ranibizumab were administered monthly. The presence of choroidal neovascular membrane associated with unilateral retinitis pigmentosa has not been previously reported. The patient improved with intravitreal ranibizumab.
