[Perimetric and visumetric methods for measuring individually tolerated intraocular pressure in glaucoma].
These techniques are used in far-advanced cases of glaucoma when the campimetric method is not practicable due to a considerable loss of visual field. The patient takes a mixture of glycerol and ascorbic acid as a hypotensive agent, his visual field or visual acuity and intraocular pressure are checked every 30 minutes. The intraocular pressure determined together with the maximum field size or with the best visual acuity is considered the individually tolerated value. The average was 21.9 mmHg. The aim in treating glaucoma should be to maintain an intraocular pressure not exceeding the tolerated value; if this cannot be achieved with drug therapy surgery is indicated.
