Evaluation of relationship between retinal microaneurysm and macular edema in eyes with branch retinal vein occlusion (BRVO)
Not Applicable
- Conditions
- Branch Retinal Vein Occlusion
- Registration Number
- JPRN-UMIN000033595
- Lead Sponsor
- Department of Ophthalmology and Visual Science, Nagoya City University Graduate School of Medical Sciences
- Brief Summary
Focal bulge and saccular types were frequently observed and strongly associated with macular edema. The risk factors for these microaneurysms formation were not identified. The size of microaneurysm was inversely correlated with the retinal thickness. The change of the size after treatment was not significant.
