Problems of intraocular pressure and the early period of primary open-angle glaucoma

The author presents the up-to-date opinions on the problem of "normal" intraocular pressure connecting it with another hydro- and haemodynamic parameters of the eye. Subsequently he discusses the contradictory opinions whether one has to distinguish two clinical conditions: intraocular hypertension and the initial period of open angle glaucoma. According to the author the initiation of the ++anti-glaucoma treatment should be considered individually in each particular case but before the onset of changes at the fundus and before the impairment of the visual field.
