Isolated “irido-choroidal vitiligo” in a young diabetic girl with no skin involvement

Abstract: Background: To describe a rare case of a diabetic patient afflicted with choroidal vitiligo and iris vitiligo with no skin symptoms and signs.
Case Report: We present the case of a 12-year-old girl diagnosed with choroid nevus, with a history of 7 years of insulin-dependent diabetes mellitus. Fundus examination revealed bilateral extensive patchy choroidal depigmentation. There was no sign of choroidal nevus or ocular inflammation, retinal and/or retinal pigment epithelial changes on OCT and fluorescein angiography. Iris vitiligo was found in her right eye. Another interesting point about this patient is the absence of associated cutaneous vitiligo observed in all previous reported cases.
Throughout the 1-year follow-up, no documented progression of this choroidal vitiligo was seen.
Conclusions: Choroidal vitiligo is a rare idiopathic benign process, possibly accompanied with iris vitiligo and no skin involvement.
