목적 : This retrospective study was to identify clinical characteristics of the branch retinal vein occlusion (BRVO). We would like to analyze the effect of the failure to dip during night blood pressure(BP) on the visual outcomes for BRVO patients.
방법 : Thirty-five patients with BRVO during 2015 to 2018 were retrospectively analyzed. It was diagnosed through complete ophthalmic examination which was including fundus photography, optical coherence tomography(OCT) and fundus fluorescein angiography(FFA). We measured 24-hour ambulatory BP in all patients with BRVO. We evaluated the mean BP dipping pattern which defined as the ratio of difference in mean day and night systolic BP. And we compared between dipper group and non-dipper group within BRVO patients to analyse the visual acuity, macular condition and edema state in the both eyes.
결과 : Systolic and diastolic mean BP at night was 135/86mmHg in non-dippers and 122/76mmHg in dippers (p=0.003). The mean logarithm of the minimum angle of resolution (logMAR) visual acuity at first (baseline) visit was 0.60±0.47 vs. 0.30±0.36 in non-dipper group and dipper group, respectively ( p=0.041). The mean logMAR visual acuity at final visit was 0.35±0.28 vs. 0.02±0.12 in non-dipper group and dipper group, respectively (p=0.001). Average systolic BP dipping ratio(%) was significantly associated with the final visual acuity(r= -0.148; p=0.022).
결론 : Visual acuity in eyes with BRVO was significantly poor in non-dipping patients. Visual outcome was correlated with the average systolic BP dipping ratio.
