PURPOSE: To investigate longitudinal changes in rates of optic nerve head circumpapillary retinal nerve fiber layer (cpRNFL) thinning and vessel density loss in patients with primary open-angle glaucoma with or without a history of disc hemorrhage (DH).
DESIGN: Observational cohort.
METHODS: In this longitudinal study, 34 eyes with DH and 134 eyes without DH that had ≥1.5 years of follow-up and 3 optical coherence tomography and optical coherence tomography angiography follow-up scans were enrolled. A linear mixed-effects model was used to compare the rates of cpRNFL thinning and vessel density loss between DH and non-DH eyes.
RESULTS: Rates of whole image capillary density loss were faster in the DH group compared with the non-DH group (mean difference [95% confidence interval] -0.32% [-0.59% to -0.04%] per year; P = .027). Faster mean rates of vessel density loss were found in the inferotemporal, inferonasal, and nasal sectors in eyes with DH than without DH (P < .05). There was no statistically significant difference in the global rate of cpRNFL thinning between the 2 groups (P = .679). The mean rate of cpRNFL thinning was faster in the DH group compared with the non-DH group only in the inferotemporal sector (mean difference [95% confidence interval] -1.01 μm (-1.62 μm to -0.40 μm) per year; P = .001).
CONCLUSIONS: Mean rates of vessel density loss between DH and non-DH eyes were different not only in the affected area but also in the other regions. In contrast, a significant difference in cpRNFL thinning between the 2 groups was detected only in the inferotemporal sector. Disc hemorrhage is an independent predictor of faster vessel density loss in glaucoma suspects and patients with primary open-angle glaucoma.
