The influence of miotics on the visual field

ABSTRACT

This study reports the influence of miotics (pilocarpine) on the visual field by comparing two visual fields, one at the miotic state and the other at normal pupil size. The measurements from the Goldmann perimetry test of 10 ocular hypertensive eyes (7 patients) and 10 glaucomatous eyes (8 patients) were used. The visual field was analyzed using an Esterman grid for functional estimation and section paper for gross evaluation. The results were as follows; 1. A decrease in pupillary size eaused not only a decrease in the gross visual field but also a reduction in the functional visual field. 2. The pupillary size did not influence absolute scotoma.
