[Does the ocular hypertension need treatment].

The authors review the risk factors that influence conversion of ocular hypertension into primary open-angle glaucoma. They are represented mainly by advanced age and higher intraocular pressure, central corneal thickness as well as greater values of vertical and horizontal cup/disc ratios. Therapy must be immediately performed if there is a moderate or high conversion risk (e.g. elderly age, greater intraocular pressure, central corneal thinnness, greater cup/disc ratio) (10% of cases). Should these factors be missing (more than 90% of the patients) then the treatment is not necessary, the only thing that has to be done is thorough monitoring of these patients.
