Introduction : To evaluate the anatomical and functional outcomes of pars plana vitrectomy (PPV) and epiretinal membrane (ERM) peeling in 77 yr old male patient with old branch retinal vein occlusion (BRVO) The prevalence of ERMs in patients with RVO ranges between 14 and 16%, but it is likely underestimated. ERM may exacerbate macular edema in patients with RVO, may reduce drug penetration of intravitreal antiangiogenic agents, and may eventually progress to a pseudohole, or more rarely, a macular hole. Therefore, patients with RVO may potentially benefit from surgical removal of ERM. In our case 77 yrs old male went to doctor with the complaint of sudden painless dimness of vision of Lt eye 1st time in 2017.Pt was hypertensive ,well controlled with medication. After proper examination & investigations he was advised for intra vitreal anti VEGF for BRVO with macular oedema, ERM (showed in OCT print done in 2017 1st). Then he had multiple anti VEGF injections, sectoral laser. In his earlier treatment period, macular oedema responded to treatment (anti VEGF inj , sectoral laser ).BCVA also improved, macular thickness decreased on OCT .But after few months, recurrent BCVA decreased ( both distance & near) in Lt eye . On OCT macular thickness increased again. This time macular oedema was nonresponding to medical treatment, anti VEGF injection. Then came COVID period in our life. Pt did not have any kind of treatment for recurrent decrease vision in his Lt eye. Then he came to our hospital in November 2021. After clinical examination, investigations found that the cause of decreased vision in his Lt eye was recurrent macular oedema with prominent ERM on OCT due to Old BRVO. After discussion of the therapauetic options (like observation vs surgical intervention) to pts himself & his family member pt agreed for surgical intervention (PPV & ERM removal & AFX) in his Lt eye. Best-corrected visual acuity (BCVA) values and spectral-domain OCT (SD-OCT) scans were recorded at each visit after surgery. After surgery BCVA improved (Distant & Near) in Lt eye, Macular thickness reduces (found on OCT) done in each visit. Conclusions: PPV and ERM removal provided encouraging functional and morphological results in eye with Old BRVO. Integrity of the outer retina and preservation of inner retinal segmentation were associated with better visual and anatomical outcomes after ERM removal, respectively.
