Details of case 4.  A: A 46 year-old female with type 2 diabetes mellitus for 15 years showed extramacular proliferations (white arrows) and preretinal heme over the posterior pole, with visual acuity lowering to 6/36. Following vitrectomy and membrane peeling with 20% SF6 endotamponade in the left eye, the patient's visual acuity improved to 6/6 at the 6 week post-operative visit. B: An oval full-thickness retinal break along the superonasal arcade posterior to the equator is observed 13 months after primary vitreous surgery (black arrow). Sclerosed superonasal retinal vessel (red arrow). C: An OCT scan of the retinal break revealed a large atrophic full-thickness retinal hole with no overlying traction. The retinal layers surrounding the retinal break were disorganized, as seen on the OCT. No prophylactic laser barrage was done surrounding the retinal break. D: At the last follow-up visit, 20 months after the primary vitrectomy surgery, there was no change in the retinal break (red arrow), and no new retinal breaks had developed. There was no development of retinal traction or subretinal fluid around the retinal break
