Condition(s) targeted: Vitrectomy
Intervention: Vitrectomy w/o ILM peeling for macular edema with BRVO (Procedure)
Phase: N/A
Status: Completed
Sponsored by: Shinjo Ophthalmologic Institute Official(s) and/or principal investigator(s):
Kazuyuki Kumagai, MD, Principal Investigator, Affiliation: Shinjo Ophthalmologic Institute
Summary
To evaluate the long term outcomes of pars plana vitrectomy (PPV), with and without internal
limiting membrane (ILM) peeling, in eyes with persistent macular edema secondary to branch
retinal vein occlusion (BRVO).
Results suggest the following hypothesis:
- PPV, with and without ILM peeling, appears to be beneficial in eyes with persistent
macular edema due to BRVO
- Effectiveness is maintained long term
- ILM peeling does not significantly affect postoperative best corrected visual acuity
(BCVA)
