Microscopic Observation of Proliferative Membranes in Fibrocontractive Retinal Disorders

Figure 7

Morphological characteristics of adherent cells to the membranes surgically excised. (a, b) Rounded cells with a hole/indentation along the course of the collagen fibres, from the internal limiting membrane (ILM) specimen. (c) Rounded cells with short and long microvilli, from the epiretinal membrane (ERM) specimen. Elongated cells with regular (d) and irregular (e) villi from the proliferative vitreoretinopathy (PVR) specimen, corresponding to retinal pigmented epithelium (RPE) cells. (f) Globular arrangements of irregularly shaped granules and of microgranules with ovoid and needle shape. Scanning electron microscopy, HV-SEM mode, original magnifications ranging from 4000 to 10000 times.
