CaseHPOFreeText: skin papules, CNV in right eye, angioid steaks, peau d'orange, peripheral comet lesions and macular atrophy at the poseterior pole (more severe in left eye). Juxtafoveal pigmented scar in right eye and fibrotic tissue at the interpapillomacular region in left eye. Pattern dystrophy-like changes were evident at posterior pole. OCT scan showed subretinal fluid with ellipsoid zone abnormalities at the fovea with juxtafoveal hyperreflective alteration corresponding to the fundus scar in the right eye.
