PURPOSE: To evaluate quantitatively the structural characteristics and associated features that antedate the occurrence of disc hemorrhage in patients with glaucoma. METHODS: Retrospective observation case series. A total of 4018 pairs of stereoscopic optic disc images obtained over 15 years were reviewed. All eyes with optic disc images before the occurrence of disc hemorrhage were enroled. The disc images were evaluated in a masked fashion with respect to general neural rim and peripapillary appearance. RESULTS: The optic disc characteristics and associated features that most antedate the disc hemorrhage in 33 eyes of 26 patients who had had previous optic disc images for evaluation were focal neural rim notch (36%), thin sloping rim (42%), peripapillary atrophy (79%), and superior-inferior rim asymmetry (73%). In eyes with pre-existing focal rim notches, all subsequent disc hemorrhages were identified at or adjacent to the notches. CONCLUSIONS: Focal rim notching may precede the occurrence of a disc hemorrhage.
