Summary
A rare "napkin-ring" subretinal membrane, a form of subretinal proliferation, was surgically removed from a patient with funnel-shaped retinal detachment. Histopathology revealed retinal pigment epithelium (RPE) and myofibroblasts as key cellular components.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Pathology
Background:
- Subretinal membranes can cause retinal detachment.
- Unusual presentations of subretinal proliferation require further investigation.
Observation:
- A unique "napkin-ring" subretinal membrane was observed in an 80-year-old male patient with total funnel-shaped retinal detachment.
- Surgical intervention included pars plana vitrectomy, relaxing retinotomy, membrane excision, and silicone oil injection.
Findings:
- Histopathologic examination identified retinal pigment epithelium (RPE) as the primary cell type in the excised membrane.
- Myofibroblasts were the predominant cellular constituents, potentially correlating with the degree of retinal contraction.
Implications:
- Understanding the cellular composition of "napkin-ring" membranes can inform surgical strategies for complex retinal detachments.
- This case highlights the role of RPE and myofibroblasts in the pathogenesis of certain subretinal proliferative disorders.
