Optic Disc Hemorrhage
Disc hemorrhages are characteristic linear hemorrhages perpendicular to the optic disc, most commonly on the superotemporal or inferotemporal margin. Although the cause of disc hemorrhages has not been fully characterized, mechanical and vascular hypotheses with evidence supporting both have been proposed. Although disc hemorrhages can occur in eyes with no signs of glaucoma, in glaucomatous eyes, disc hemorrhages are a risk factor for progression. Disc hemorrhages themselves cannot be treated but their presence may warrant intensification of intraocular pressure lowering therapy. The purpose of this article is to provide a review of disc hemorrhage for the trainee or practicing ophthalmologist.
Alternate names: optic disc hemorrhage, Drance hemorrhage, splinter hemorrhage, nerve fiber layer hemorrhage.
Disease: Disc Hemorrhages
Disc hemorrhages are splinter or flame-shaped hemorrhages oriented perpendicular to the optic disc margin. Classically, these hemorrhages are located in the prelaminar optic disc, cross the peripapillary zone, and extend into the adjacent superficial retinal nerve fiber layer, although they may not occupy the entire length from disc to retina. Alternately, deeper disc hemorrhages may appear round and blotchy. Less commonly, a disc hemorrhage may be noted in the peripapillary retinal nerve fiber layer reaching within one disc diameter of the optic disc margin.
