Vitrectomy for Branch Retinal Vein Occlusion
Completed
- Conditions
- Vitrectomy
- Interventions
- Procedure: Vitrectomy w/o ILM peeling for macular edema with BRVO
- Registration Number
- NCT00685490
- Lead Sponsor
- Shinjo Ophthalmologic Institute
- Brief 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)
