Purpose: To measure the changes in optic disk morphology after unilateral disk hemorrhage and to compare the changes between eyes.
Design: Observational case series.
Methods: 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.
Results: 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).
Conclusions: 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.
