Ocular Hypertension (OHT)

Normal intraocular pressure ranges between 5-21 millimeters of mercury (mmHg) with the average value at 15 mmHg. The intraocular pressure can vary during the day (diurnal variation) and depending on personal factors. Ocular hypertension increases risk of glaucoma, but not every ocular hypertension patient has glaucoma. It depends on whether the optic nerve is damaged or not. Ocular hypertension patients are categorized as a glaucoma suspect. That is why this group of patient needs to see and follow up with an ophthalmologist and take good care of themselves on a continual basis.

There might not be any symptoms shown, but when checked, intraocular pressure is higher than 21 mmHg.
  • Family history of glaucoma risk, or family members have glaucoma.
  • Diabetes patients
  • 40 years old and above
  • Thin corneas in the center
  • Hypertension patients
  • African-American or Hispanics heritage
  • Cardiovascular and heart diseases patients
  • Very short-sightedness
Ocular hypertension increases risk of glaucoma.
  • Your ocular pressure and optic disc will be checked by the ophthalmologist.
  • Your visual field will be checked by computerized machine.
  • The thickness of retinal nerve fiber layer around optic disc will be checked by optical coherence tomography (OCT).
Basically, your ophthalmologist will be following up with you regularly except in cases of very high pressure or high risk, the ophthalmologist might start treatment immediately. If left untreated patients could develop glaucoma soon.
Regular follow up with the ophthalmologist to assess glaucoma risk.
