Disc hemorrhages are characteristic linear hemorrhages perpendicular to the optic disc, most commonly on the superotemporal or inferotemporal margin. The cause of disc hemorrhages has not been fully characterized, and mechanical and vascular hypotheses with evidence supporting both have been proposed.

2014年5月1日 · What Is a Disc Hemorrhage? A typical DH in an eye with glaucoma appears as a splinter-like or flame-shaped area of bleeding, usually with feathered ends and oriented perpendicular to the disc margin (Fig. 1). The most common location of DH is at the temporal aspect of the disc.

Optic disc hemorrhage is a common clinical feature of glaucoma, indicating active disease with likely progression and visual field loss. These small bleedings form notch-like lesions at the edge of the optic disc in the nerve fiber layer and often correlate with visual field loss.

2023年10月22日 · An optic disc hemorrhage refers to the sudden appearance of bleeding within the optic nerve head, which is the point where the optic nerve enters the eye. This condition can be an important indicator of underlying ocular and systemic health issues.

Posterior vitreous detachment, elevated resistance of the central retinal vein, diabetic retinopathy or diabetic microvascular disease, leukemia, optic disc drusen, lupus, use of antiplatelet agents, and different types of optic neuropathy have been shown to manifest various degrees of disc hemorrhage. 1-6 Using ODH alone as evidence of ...

In this comprehensive study, we characterize optic disc hemorrhages in relation to glaucoma type, optic disc phenotype, IOP, VF loss, and morphological features and patterns of microbleeds. Understanding clinical characteristics in relation to hemorrhages of the optic nerve head may provide added insights into glaucomatous damage.

Optic disc hemorrhage (DH) was initially considered a precursor for a glaucomatous change because DH is detected before the diagnosis or progression of glaucoma.

2008年10月31日 · In glaucoma patients, disc hemorrhages are markers for a complex vasculopathy that is just beginning to be understood. They are also predictors of progressive glaucomatous disease independent of intraocular pressure (IOP) and other factors.

2017年8月15日 · O ptometrists have yet to reach a consensus on the meaning of optic disc hemorrhage (ODH) and management of patients when it develops. We don’t know what causes ODH. Some even consider the development of an ODH to be progression of disease.

2017年11月1日 · Optic disk hemorrhage is best known for its association with visual field loss and progression in patients with glaucoma; however, it may occur in conjunction with other ocular or systemic conditions as well as in healthy individuals. It may also be the first sign of a sight-threatening condition.
