Microscopic Observation of Proliferative Membranes in Fibrocontractive Retinal Disorders

Figure 4

Pigmentation score of different specimens analysed in the study. Membranes from a macular pucker with pigmentation score 0: conventional epiretinal membrane (a); conventional epiretinal membrane removed with the internal limiting membrane (ERM + ILM) (b); internal limiting membrane (ILM) (c). (d, e) Atypical epiretinal membrane (A ERM) associated with lamellar macular hole (LMH) with pigmentation score 1. Specimens of membranes from diabetic retinopathy (DR) with score 1‐2: ERM from DR (f); ERM + ILM secondary to DR (g); ILM from ERM secondary to DR with pigmentation score 1 (h). Specimens with pigmentation score 3: ERM from RD with FTMH pigmentation score 3 (i); ERM from RD after PPV + PDMS with pigmentation score 3 (j); ERM associated with retinoschisis with pigmentation score 3 (k). (l–n) Proliferative vitreoretinopathy (PVR) specimens with pigmentation score 3.
