Risk factors and incidence of Macular Edema in eyes with retinal Vein Occlusion after uneventful cataract surgery: The MEVO study

The study demonstrates that RVO eyes with previous CME requiring intravitreal treatment are at significant risk of postoperative macular edema after uneventful cataract surgery, and this risk increases in people with diabetes. The incidence is not affected by the type of RVO. Considering almost 2/3 rd of PME developed within the 1 st month of surgery, we recommend a routine OCT scan as a part of postoperative assessment at the 1 st visit after surgery, in eyes at risk. Eyes developing PME may have poorer visual outcomes, especially eyes with CRVO; hence, patients need to be counseled carefully regarding outcomes of cataract surgery. The outcomes might depend on the previous treatment course they have received, and they may need to undergo a repeat cycle of treatment due to a risk of return of macular edema.
