Bilateral idiopathic choroidal hyperpigmentation

To report a series of cases showing bilateral circumpapillary hyperpigmentation on routine fundus examination.

In this observational case series, three patients showing bilateral circumpapillary hyperpigmentation on routine fundus examination were included. Multimodal retinal imaging was done for these cases.

Multimodal imaging of the lesion showed the hyper pigmentation to be confined to the choroid. The optical coherence tomography scans described the features through the hyperpigmented area, adjacent hypopigmented area and the normally pigmented area of the fundus as suggestive of choroidal hyper melanosis. Follow-up of these lesions over a period of 2-6 years showed no change in the vision or characteristics of the lesion.

Bilateral circumpapillary hyperpigmentation needs to be considered as a differential for bilateral peripapillary pigmented lesions.
