Ocular hypertension is a condition where the measured intraocular pressure is higher than 24 mmHg, but no glaucomatous visual field loss or optic nerve damage has occurred. In the landmark Ocular Hypertension Study (OHTS) there was shown to be a 5-year risk of conversion to glaucoma in approximately 9.5% of patients. Factors which increase the risk of conversion to glaucoma (and therefore increase probability of starting treatment) include:

•Higher pressure at presentation.

•Older age at presentation.

•Thinner corneas.

•Increased cup/disc ratio.

•Afro-Caribbean heritage.

•Males are more likely to convert to glaucoma than females.
