Microscopic Observation of Proliferative Membranes in Fibrocontractive Retinal Disorders

Figure 8

Immunohistochemical staining for CD68 or anti-α-SMA. (a, b) CD68 staining of epiretinal membrane (ERM) specimens. Macrophages appear as brownish agglomerate. (c, d) Anti-α-SMA staining of epiretinal membranes (ERM) associated with lamellar macular hole (LMH). Conventional ERM (c) appears brown due to the positive stain compared to the atypical epiretinal membrane (A ERM) (d). OCT images are given in the insets.
