From: Microaneurysms cause refractory macular edema in branch retinal vein occlusion
The time of microaneurysm formation in patients with macular edema in branch retinal vein occlusion.
Patients, Thirty-seven eyes of 37 patients (18 men, 19 women), in whom the time of microaneurysm formation after BRVO onset was identified. (A) Representative optical coherence tomography (OCT) angiograms in patients with macular edema (ME) in branch retinal vein occlusion (BRVO). Top row, superficial capillary layer of the retina. Bottom row, deep capillary layer of the retina. Microaneurysms (arrows) formed on month 6. (B) The time of microaneurysms formation after BRVO onset. In 19 eyes (51%) of 37 eyes, microaneurysms were detected within 6 months after BRVO onset and in 31 eyes (84%) of 37 eyes within 9 months (average formation time, 6.1 ± 3.1 [mean ± standard deviation] months).
