Presumed choroidal naevi and sensory retinal detachment.

Two cases of choroidal naevus in patients with presenting complaints of blurred central vision and subsequent findings of abnormal retinal pigment epithelium (RPE) overlying the pigmented choroidal lesion are presented. Fluoroangiographic evidence of sensory retinal elevation in these areas is provided. Both cases were treated with low-intensity argon laser photocoagulation, with return of central vision without complication. The diagnostic importance of morphologically altered RPE, particularly lipofuscin pigment, overlying such choroidal tumours is stressed. A significant period of follow-up in each case is documented photographically.
