This was an evaluation of patients within the Early Manifest Glaucoma Trial. It's purpose was:
"To evaluate the effect of intraocular pressure (IOP)-reducing treatment on the development of disc hemorrhages in patients with glaucoma."
The conclusion was:
"IOP-reducing treatment was unrelated to the presence or frequency of disc hemorrhages. The results may suggest that disc hemorrhages cannot be considered an indication of insufficient IOP-lowering treatment, and that glaucoma progression in eyes with disc hemorrhages cannot be totally halted by IOP reduction. The results also suggest that disc hemorrhages do not occur in all patients with glaucoma."
