Acute macular pucker.

Abstract

PURPOSE: To describe the presenting features, histopathology, and surgical outcome in a group of patients with rapidly progressive macular pucker. DESIGN: Retrospective interventional noncomparative case series. PARTICIPANTS: Five patients. METHODS: Review of case notes and the existing literature. RESULTS: All five patients had rapidly progressive visual loss and metamorphopsia over 2 weeks to 3 months, secondary to macular pucker after retinal tears or detachment. Vitrectomy and epiretinal membrane removal was performed within 1 month of diagnosis. In the absence of complications, there was rapid recovery of the visual acuity with resolution of metamorphopsia within 6 weeks to 3 months. Surgical complications limited the visual outcome in two cases. Histopathologic examination of epiretinal membrane removed from two of the cases suggests that these tend to form tubuloacinar structures and contain more retinal pigment epithelium-derived cells than tissue excised from cases with idiopathic macular pucker. CONCLUSIONS: Patients with acute macular pucker have precipitous visual loss caused by epiretinal membrane formation after retinal tear or detachment. Early surgery in these patients results in rapid recovery of visual acuity and resolution of metamorphopsia. The clinical features and comparative immunohistochemistry suggest that acute macular pucker is a distinct clinicopathologic entity.
