Polypoidal lesions associated to choroidal naevus: spectrum of pachychoroid disease?

A 78-year-old woman was referred by an optician for an incidental finding of peripapillary naevus in the absence of visual symptoms. On examination, the right eye showed a choroidal naevus of around 1.5 disc diameter, adjacent to the optic disc. Optical coherence tomography detected the presence of pigment epithelium detachment and subretinal fluid within the context of the naevus. Fundus fluorescein angiography and indocyanine green showed multiple polypoidal lesions (Polypoidal Choroidal Vasculopathy, PCV) in the choroid within the spectrum of a pachychoroid, without any sign of malignancy related to neovascularisation. The patient underwent a follow-up of 6 months, showing stability of the lesions over this timeframe. No treatment has been required since the polypoidal lesions were outside the fovea and visual acuity remained stable. The association between choroidal naevi and polypoidal lesions is rare¹; however, this seems to confirm that these findings are part of the spectrum of pachychoroid disease.
