Abstract

Four patients with pigment epithelial detachment due to age-related macular degeneration underwent clinical examination and optical coherence tomography (OCT) scan. A ring-shaped pattern on the fast retinal thickness maps of the OCT was observed for all of these patients with little central retinal thickness but increasing retinal thickness at the edge of the pigment epithelial detachment. The authors have coined the term “ring sign” to describe this pattern typically seen on the OCT scan in patients with pigment epithelial detachment with or without underlying choroidal neovascularization.
