Purpose:We report two cases of exudative retinal detachment with a characteristic distribution of subretinal fluid (SRF) on optical coherence tomography (OCT) after vitrectomy for proliferative diabetic retinopathy (PDR).Case summary: A 54-year-old woman diagnosed with PDR and vitreous hemorrhage (VH) was treated with pars plana vitrectomy combined with endolaser photocoagulation and cataract surgery.Based on a diagnosis of PDR and VH, a 66-year-old man underwent vitrectomy and endolaser photocoagulation.In both cases, exudative retinal detachment was observed on OCT a few days after surgery.On OCT vertical section, the SRF was mainly distributed in the inferior and superior regions of the fovea, while sparing the foveal center.The patients were followed via observation, and SRF resolved spontaneously.Conclusions: Our two cases suggest that excessive endolaser photocoagulation during vitrectomy may cause exudative retinal detachment.
