Drance hemorrhage


Disc hemorrhages that lie within the peripapillary retinal nerve fiber layer are known as Drance hemorrhages.

Occur more often in patients with normal-tension glaucoma.

Seen in as many as 43% in one prospective study in these patients with normal-tension glaucoma.

Can also occur in patients with primary open-angle glaucoma, especially if treatment is inadequate.

Associated with an increased risk of cupping, worsening atrophy of the nerve fiber layer, and progressive visual field loss after one year.

It indicates disease progression and there is a need to start or to increase the dosage of medical therapy.
