The occurrence of optic disc hemorrhage in glaucoma has been noted for many years, but it has only been in the last 40 years that the association between disc hemorrhage and glaucoma progression has been realised. Normal-tension glaucoma patients have the highest prevalence of disc hemorrhage, but such hemorrhages occur in all types of glaucoma. The exact pathogenesis of disc hemorrhage is unknown, but primary vascular dysregulation appears to be the most likely cause in eyes with glaucoma. Optic disc hemorrhages have been associated with the progression of glaucomatous optic nerve damage and the progression of visual field defects. Lowering intraocular pressure (particularly with trabeculectomy) has been shown to reduce the occurrence of optic disc hemorrhage in glaucoma. (copyright) 2010 Expert Reviews Ltd.
