To measure the changes in optic disk morphology after unilateral disk hemorrhage and to compare the changes between eyes.
Observational case series.
Ten glaucoma patients who had a unilateral disk hemorrhage were enrolled. The baseline measurements obtained by Heidelberg Retina Tomograph (HRT) were performed on both eyes when a disk hemorrhage was detected, and the second measurements were done after an average of 32 +/- 19 months. The amount of change and the percent change in the HRT parameters from the baseline measurements of the hemorrhagic eyes were compared with those of the contralateral nonhemorrhagic eyes.
The reduction in the neuroretinal rim area and the decrease in volume were significantly greater in the octant with the disk hemorrhage than measured in the contralateral eyes (P =.002, Wilcoxon signed rank test).
This study demonstrated quantitatively that the progression of optic disk damage in glaucoma is faster in eyes with disk hemorrhage than in eyes without disk hemorrhage.
测量单侧视盘出血后视盘形态的变化，并比较双眼之间的变化。
观察性病例系列。
纳入10例单侧视盘出血的青光眼患者。当检测到视盘出血时，对双眼进行海德堡视网膜断层扫描仪（HRT）的基线测量，第二次测量在平均32±19个月后进行。将出血眼HRT参数相对于基线测量的变化量和变化百分比与对侧未出血眼进行比较。
视盘出血所在象限的神经视网膜边缘面积减少和体积减小显著大于对侧眼（P = 0.002，Wilcoxon符号秩检验）。
本研究定量表明，青光眼患者中，视盘出血眼的视盘损害进展比无视盘出血眼更快。
