PURPOSE: To evaluate the efficacy of autologous blood injections for treating overfiltering or leaking blebs after glaucoma surgery. METHOD: Retrospective review of ten eyes of ten patients who received intrableb autologous blood injections for hypotonous maculopathy. RESULTS: After intrableb blood injection, average intraocular pressure increased from 4.3 mm Hg to 6.4 mm Hg, and average visual acuity improved from 20/88 to 20/77. These results, however, were not statistically significant. CONCLUSION: Our results with autologous blood injection are less favorable than those of previous reports, although further study with a larger case series is needed.
