A case of primary choroidal vitiligo
The following case appears in the Digital Journal of Ophthalmology.

A 43-year-old woman with cutaneous vitiligo (A) presented at the Aravind Eye Hospital for a routine eye examination. Visual acuity was 20/20 in the right eye and 20/40 in the left eye. Anterior segment examination was normal in the right eye and showed an early-stage cataract in the left eye. There were no signs of ocular inflammation.

Fundus examination showed a flat, depigmented patch in the macula of the right eye and superonasal to the optic disc in the left eye (B-C, arrowheads). Enhanced-depth optical coherence tomography (EDI-OCT) scans through the lesions showed normal retinal and choroidal layers (D-E). (The blur in E is an unavoidable artifact associated with use of a 50° lens with the Spectralis OCT. Ultrasonography was normal.

A diagnosis of choroidal vitiligo was made.

Learning Points:-
- This patient had no underlying autoimmune disease and no signs of previous ocular inflammation.

- The differential diagnosis for flat depigmented fundus lesions include amelanotic choroidal nevus, choroidal osteoma, diffuse choroidal hemangioma, amelanotic melanomas, and chorioretinal atrophy, all of which show characteristic abnormalities on EDI-OCT or USG.
