Choroidal Neovascularisation Following Epiretinal Membrane Surgery: Case Series



To report unusual complication of sub retinal choridal neovascularisation (SRNVM) following uneventful epiretinal membrane surgery;


Retrospective case series at University Hospital Southampton, United Kingdom


A total of 2 cases underwent uneventful combined phacoemulsification, pars plana vitrectomy and membrane peel for epiretinal membrane. Both patients developed sub retinal choridal neovascularisation within 6 months post surgery resulting in rapid deterioration of vision. They have been started on ant-VEGF therapy which has stabilised the vision to pre-op level. There were no specific identifiable factors either pre-op/perop or post operative period that could explain the sudden onset of this condition. All possible causative and associated factors are explained.


Pars plana vitrectomy is now increasing performed in elderly population. The health of epithelium which acts as a barrier to development against SRNVM declines with age and there may not be obvious signs of macular degeneration in early stage. However, the inflammation induced by retinal surgery may just be enough to trigger the decline and result in SRNVM. The series highlights the need for careful preop evaluation and information could be useful for informed consent.
