Seol BR, et al. - Analysts compare glaucoma progression between unilateral and bilateral disc hemorrhage (DH) eyes and aim to ascertain the related risk factors. The outcome suggests unilaterality of DH is related to glaucoma progression in bilateral primary open-angle glaucoma (POAG) patients with DH. Therefore, clinicians need to perform careful and frequent follow-up on bilateral POAG patients demonstrating DH in only 1 eye amid the follow-up period.
