Purpose:
To report three cases of choroidal neovascularization (CNV) that occurred following surgical disruption of Bruch membrane during macular surgery.
Methods:
A retrospective case series was compiled. Macular translocation surgery with punctate retinotomy was performed in two patients for subfoveal CNV, and pars plana vitrectomy with epiretinal membrane (ERM) peeling was performed in one patient for idiopathic ERM.
Results:
CNV developed at a site of subretinal cannulation in two cases of macular translocation, and at a site of inadvertent injury to Bruch membrane with a vitreoretinal pick in the one case that underwent ERM peeling.
Conclusions:
These cases underscore the need to monitor breaks in Bruch membrane for CNV following macular surgery.
