Subretinal "Napkin-Ring" Membrane in Proliferative Vitreoretinopathy
Arch Ophthalmol. 2000;118:1287-1289.
A "napkin-ring" subretinal membrane is an unusual expression of subretinal proliferation associated with retinal detachment. An 80-year-old man with a total funnel-shaped retinal detachment underwent pars plana vitrectomy, 360° relaxing retinotomy, excision of a subretinal napkin-ring membrane, and silicone oil injection. Histopathologic examination of the removed napkin-ring subretinal membrane revealed the presence of retinal pigment epithelium (RPE) as the major source of cells within the membrane. Myofibroblasts were the most common cellular constituents; the total number of these cells may have correlated with the degree of clinical contraction, causing a funnel-shaped retinal detachment.
