Causes of macular hole formation after procedures of rhegmatogenous retinal detachment

Objective　To investigate the causes of macular hole formation after surgery for rhegmatogenous retinal detachment.Methods　The medical records of all patients undergoing rhegmatogenous retinal detachment surgery in the Department of Ophthalmology, Renmin Hospital of Wuhan University from October 2017 to December 2019 were retrospectively analyzed. We screened out patients with macular holes after surgery, and speculate the causes of macular hole formation by optical coherence tomography (OCT).Results　A total of 409 patients (423 eyes) with rhegmatogenous retinal detachment surgery were included in this study, of which 341 eyes underwent vitrectomy, 78 eyes underwent scleral buckling, and 4 eyes underwent encirclingscleral buckling. Retrospective analysis showed that macular holes occurred in 3 eyes of 423 eyes undergoing retinal detachment surgery, the incidence was 0.71%. Among them, 2 eyes occurred after vitrectomy, and the occurrence time was on day 21 and 30 after the operation, with the incidence being 0.59%. One eye occurred after the scleral buckling, and the occurrence time was on day 5 after the operation, with the incidence of 1.28%. All patients with macular holes underwent vitrectomy with internal limiting membrane peeling. The macular holes were closed and the visual acuity improved.Conclusion　Macular hole after rhegmatogenous retinal detachment surgery is rare. In addition to the epiretinal membrane, it is also related to macular-off retinal detachment, residual vitreous cortical traction and the traction of gas bubble on the macular.
