Abstract

• During rhegmatogenous retinal detachment, two major phagocytic cell populations can be identified in the subretinal fluid. Routine light and electron microscopic studies may be inadequate to assess quantitatively the free-floating retinal pigment epithelial cells and the macrophagic retinal pigment-laden cells. Enzyme histochemical staining permits a simple, rapid, reproducible method of identifying each cell type. This cytologic biochemical differentiation is an important tool for reexamination of the theories associated with subretinal fluid cell activity.
