[Planimetric studies of the behavior of the visual field following glaucoma operations].

This article presents the results of functional investigation of the central and peripheral visual fields of 30 patients 3 years after glaucoma surgery. The authors studied the relationship between intraocular pressure and the site of the visual field, and also between vision and the quality of the central visual field. The results of the investigation support the demand for early surgery in glaucoma cases. Patients should be advised and informed thoroughly, because in 36 percent of all cases the cataract grows postoperatively.
