Evaluation of collateral vessels on optical coherence tomography angiography in macular edema associated with branch retinal vein occlusion (BRVO)
- Conditions
- Branch Retinal Vein Occlusion
- Registration Number
- JPRN-UMIN000033870
- Lead Sponsor
- Depertment of Ophthalmology and Visual Science, Nagoya City University Graduate School of Medical Sciences
- Brief Summary
Collateral vessels around the macula were detected in 25 out of 30 eyes and were already formed at the initial visit. The macular edema was resolved in 16 out of 25 eyes with collateral vessels and 2 out of 5 eyes without collateral vessels, respectively. The mean duration of macular edema resolution was 13 months with collateral vessels and 15 months without collateral vessels, respectively, which was not significantly difference. Eight eyes of 22 eyes who underwent fluorescein angiography had leaky collateral vessels and microaneurysms were detected in all the eyes, whereas the other 14 eyes had nonleaky collateral vessels and microaneurysms were detected in 7 eyes.
