Ocular Hypertension


Ocular hypertension cannot be prevented, but through regular eye examinations with an ophthalmologist, its progression to glaucoma can be prevented.


The prognosis is very good for people with ocular hypertension.


  • With careful follow-up care and compliance with medical treatment, most people with ocular hypertension do not progress to primary open-angle glaucoma, and they retain good vision throughout their lifetime.

  • With poor control of elevated intraocular pressure, continuing changes to the optic nerve and visual field that could lead to glaucoma might occur.

Support Groups and Counseling

Educating people with glaucoma is essential for medical treatment to be successful. The person who understands the chronic (long-term), potentially progressive nature of glaucoma is more likely to comply with medical treatment.

Numerous handouts about glaucoma are available, two of which are listed below. 

  • "Understanding and Living with Glaucoma: A Reference Guide for People with Glaucoma and Their Families," Glaucoma Research Foundation, (800) 826-6693.
  • "Glaucoma Patient Resource: Living More Comfortably with Glaucoma," Prevent Blindness America, (800) 331-2020.

Media file 2: Elevated eye pressure is caused by a build-up of fluid inside the eye because the drainage channels (trabecular meshwork) cannot drain it properly. Elevated eye pressure can cause optic nerve damage and vision loss.
