what is ocular hypertension
Ocular hypertension Ocular hypertension is a clinical term describing the presence of elevated intraocular pressure in the absence of optic nerve damage or visual field loss. For most individuals, the normal range of introcular pressure is between 10 mmHg and 21 mmHg. Elevated intraocular pressure is an important risk factor for glaucoma. The Ocular Hypertension Treatment Study, a large, multicentered, randomized clinical trial, determined that topical ocular hypotensive medication delays or prevents the onset of Primary Open-Angle Glaucoma.
