Primary Open Angle Glaucoma

Primary Open Angle Glaucoma is the most common type of glaucoma accounting for a majority of all glaucoma cases. The condition progresses gradually, when the eye does not drain enough fluid as well as it should (like a clogged drain). As a result, eye pressure builds and starts to damage the optic nerve. Primary Open angle glaucoma is an eye condition that can result in progressive vision loss. While the condition usually begins with slow peripheral vision loss, it can lead to permanent vision loss without treatment. It is often associated with increased intraocular eye pressure. However, it is also possible to have glaucoma in the setting of normal intraocular pressure.

Management / Treatment

Comprehensive Glaucoma Evaluation for the diagnosis involves:

  • Intraocular Pressure measurement (measuring your eye pressure).
  • Inspection of the drainage angles through gonioscope.
  • Dilated exam for Optic nerve evaluation by visualization and digital photography as well as by measurement of the nerve by tomographic nerve scan
  • Testing for Peripheral (side) vision through visual field testing
  • Measuring the thickness of your cornea


Since glaucoma can cause irreversible vision loss, treatment is aimed at preventing vision loss and halting its progression. It is essential to begin treatment as soon as the diagnosis is made in order to prevent visual deterioration.

Treating glaucoma successfully is a team effort between you and your ophthalmologist. Your ophthalmologist will determine the individualised treatment plan which may include a combination of treatments depending on the progression and severity of the glaucomatous condition. Patients are expected to see their doctor every 3-6 months for intraocular pressure checks and follow up studies.

  • Eye Drops - medicated eye drops to lower the intraocular pressure
  • Laser - Laser Trabeculoplasty - Laser energy is applied to the angle to increase outflow of fluid. This procedure is a minimally invasive treatment option
  • Surgery - Trabeculectomy or Tube Shunt placement- used for patients with advanced disease, or in whom less invasive methods have been unsuccessful
  • Endocyclophotocoagulation (ECP): This laser treatment works to alleviate intraocular eye pressure by decreasing the production of fluid within the eye
