Kang HM, et al. - In this study, researchers used spectral-domain optical coherence tomography with enhanced depth imaging to assess changes in peripapillary choroidal thickness in patients with branch retinal vein occlusion (BRVO) over 12 months. They reported a significant decrease in peripapillary choroidal thickness over 12 months in BRVO-affected eyes and nonaffected eyes in patients with unilateral BRVO.
