A representative type 3 lesion of ECE. Fundus photographs (left column) and OCT images (right column) of the left eye of patient 3. a Before treatment. The fundus photograph shows a white fluffy lesion at the posterior pole. The OCT image shows a highly reflective lesion (yellow asterisk) involving the full-thickness retina and protruding into the vitreous. Macular edema is present with subretinal fluid. The hyperreflective dots in the posterior vitreous are infiltrating inflammatory cells. b One week after treatment (vitrectomy). The OCT image shows shrinkage of the retinal lesion, formation of epiretinal membrane (yellow arrow) and reduction of the macular edema. c Three months after treatment. The retinal lesion almost resolves, and OCT shows a residual pre-retinal membrane (yellow arrow) close to the optic disc
