Sequential optical coherence tomography (OCT) scans demonstrating the possible mechanism of secondary post-vitrectomy retinal break. a: Preoperative OCT scan of the right eye fundus showing the epiretinal membrane (red arrow) extending right till the inferior arcade in a 57-year-old-male, previously operated for vitreous hemorrhage following proliferative diabetic retinopathy. Subsequently, patient redevelops vitreous hemorrhage for which he undergoes re-vitrectomy and removal of epiretinal membrane up to the retinal arcades. 2b: A residual preretinal membrane (red arrow) is noted along the inferotemporal arcade in the oblique line OCT scan done 1 month after the vitreous surgery. The inner retinal layers at that site appear disorganised with loss of retinal layer stratification and development of intraretinal cystic space. C: There is contraction of the preretinal membrane (red arrow) at the inferotemporal arcade eventually leading to development of full-thickness post-vitrectomy retinal break (white arrow) after 4 months post re-vitrectomy. There was no subretinal fluid surrounding the retinal break
