To investigate the topographic feature of optic disc hemorrhage (DH) and its clinical implications in glaucoma patients.
Seventy-one glaucoma patients with DH were enrolled and all patients were regularly followed up at 1- to 3- month intervals for at least 1 year after the initial DH. From reviewing fundus photographs, the radial and clock-hour locations of DHs were determined. According to the radial locations, DHs were divided into the following groups: (1) laminar type DH, which occurred at lamina cribrosa; (2) marginal type DH, which occurred at the border of rim and cup; (3) rim type DH, which occurred at disc rim; and (4) peripapillary DH, which were located in peripapillary area.
The first detected DHs consisted of 56.3% of rim type, 26.8% of marginal type, and 5.6% of laminar type. The laminar and marginal type DHs were more frequently observed (33.3% and 50.0%, respectively) in DHs number 3 or more than in simple DHs. The cumulative probability of optic disc deterioration was found to be significantly greater in patients with laminar and marginal type DHs than other types of DHs (P = 0.0043, log rank test).
Recurrent DH tends to occur more frequently at laminar or at the border of rim and cup. Laminar and marginal type DHs may reflect more rapid progression of glaucomatous optic disc changes than other types of DH.
