OCT changes of idiopathic epiretinal membrane after cataract surgery

Background: We reviewed our experience in the management of cataract and idiopatic epiretinal membrane surgeries at the Humanitas Research Institute-Milan, Italy- over the past 3 years. Methods: We conducted a single center retrospective observational case series of patients that underwent sequential cataract and idiopatic epiretinal membrane (ERM) surgeries from 2012-2015 in Humanitas Research Institute. Full data was obtained for 53 eyes of 57 patients. Patients with ERM secondary to uveitis or trauma or associated with simultaneous retinal detachment were excluded. Diabetic retinopathy, glaucoma, age-related macular degeneration, and myopia of more than 6 diopters were exclusion criteria as well. Results: Cataract surgery was not associated with an ERM stage progression at one month follow up, but caused retinal inflammation that resulted in a significant increase in central macular thickness (CMT), macular volume (MV), central macular edema (CME), IS/OS disruption (IS/OS) and neurosensory detachment (NSD). However, there was no significant change in Best corrected visual acuity (BCVA). Conclusion: We suggest that patients undergoing cataract surgery in the presence of epiretinal membranes need tight follow up to treat and control eventual macular inflammatory changes and eventual prompt vitrectomy if BCVA is threatened.
