Fig. 12. Light micrograph of an area over a retinal buckling element for retinal reattachment. Cryotherapy has been applied in the area, causing atrophy of the neurosensory elements of the retina. There is an intimate association of the remaining glial elements of the retina (R) with proliferated retinal pigment epithelial cells in the plane of the former subretinal space (arrow). The adhesion prevents intraretinal separation in this area. (Periodic acid-Schiff stain; × 100.)
