[Relation between optic disk changes and visual fields and the intraocular pressure values in primary glaucoma].

On the basis of archival records of 1463 patients treated in the period 1964-1986 the author isolated the cases of primary open angle glaucoma (2248 eyes) and closed angle glaucoma (333 eyes). The influence of the intraocular pressure on the grade of damage done to the nervous fibres and manifesting itself by pathological changes of the optic disc and visual field was analyzed. It was discovered that this influence was statistically significant especially in cases of closed angle glaucoma.
