Objective:
To compare visual outcomes of eyes with primary and secondary epiretinal membranes (ERM) vitrectomy with cataract extraction.

Methods:
A multi-centre electronic record review was performed. Epiretinal membranes were classified as primary or secondary to: diabetic retinopathy (DR), retinal vein occlusion (RVO), retinal detachment (RD) and uveitis. Change in vision and incidence of post-operative CME were analyzed.

Results:
554 patients with primary ERM and 241 with secondary ERM were analyzed. Postoperatively (4-12 weeks), mean vision gain was 0.2 ±0.5, 0.4 ±0.5 and 0.2 ±0.5 LogMAR in primary ERM group, RD (n=112) and RVO (n=64) subgroups (P<0.05). Mean visual gain of 0.1 ±0.2 and 0.2 ±0.5 in the DR (n=42) (P>0.05). and uveitis (n=23) (P>0.05) respectively and was not significant (P>0.05). CME developed in 6% of primary ERM group and 17% in the secondary ERM (P<0.05).ERM recurrence was nearly similar between the 2 groups (4% vs. 3%).

Conclusion:
Cataract extraction with PP and ERM peel shows improvement of vision in primary ERM and those secondary to RD and RVO. Postoperative CME rates are more in the secondary ERM.
