[Secondary pigmented macular pucker].

The clinical course and histologic findings in a case of macular pucker with secondary pigmentation are described. The macular pucker occurred following argon laser coagulation of a peripheral hole and consisted of elements of the inner limiting membrane, an extracellular matrix of collagen fibrils, and retinal pigment epithelial cells with varying degrees of differentiation. No retinal glial cells were found. The pigment epithelial cells had presumably migrated through the peripheral retinal hole and settled on the retinal surface.
