Abstract |
PURPOSE To investigate the improvement of visual acuity with the different effects of ischemic and perfusion type branched retinal vein occlusion (BRVO), and explore the relationship between defects of the macular capillary network and intravitreal injection of triamcinolone acetonide (IVTA) for treatment of BRVO secondary to macular edema. METHODS: We compared macular capillary network condition, improvement of visual acuity due to ischemic range, and decrease of macular edema between 23 perfusion type BRVO patients and 21 ischemic type BRVO patients who were treated with IVTA for BRVO secondary to macular edema. RESULTS: Both ischemic and perfusion type BRVO exhibited decreased macular edema and showed meaningful improvements in visual acuity (P<0.01), but did not show a relationship between the defects in the macular capillary network and improvement of visual acuity. No differences were seen in macular capillary network defects between ischemic and perfusion type BRVO. CONCLUSIONS: IVTA had an effect on the decrease in macular edema and improvement of visual acuity for both ischemic and perfusion type BRVO. However, defects in the macular capillary network do not seem to have any effect on the improvement of visual acuity. |
