Morphometric change analysis of the optic nerve head in unilateral disc hemorrhage cases
Ahn JK; Park KHAmerican Journal of Ophthalmology 2002; 234: 920
PURPOSE: To measure the changes in optic disc morphology after unilateral disc hemorrhage, and to compare the changes between eyes. DESIGN: Observational case series. METHODS: Ten glaucoma patients who had a unilateral disc hemorrhage were enrolled. The baseline measurements obtained by Heidelberg Retina Tomograph (HRT) were performed on both eyes when a disc hemorrhage was detected, and the second measurements were done after an average of 32 ± 19 months. The amount of change and the percentage 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 disc hemorrhage than measured in the contralateral eyes (p = 0.002, Wilcoxon signed rank test). CONCLUSIONS: This study demonstrated quantitavily that the progression of optic disk damage in glaucoma is faster in eyes with disk hemorrhage than in eyes without disk hemorrhage.
