The Short-Term Effect of 1% Tropicamide Drop on Pupillary… : Journal of Glaucoma
he purpose of this study was to evaluate pharmacological dilatation with one drop of 1% tropicamide on pupillary diameter and IOP changes in patients with PXS and glaucoma (PXG). Materials and Methods: Eighty-two patients with PXS, 78 Patients with PXG, and 35 healthy subjects were included in the study. PXG and PXS were diagnosed based on IOP assessment, corneal pachymetry, optic disc examination, visual field testing, and peripapillary retinal nerve fiber analysis. IOP and the diameter of pupil size were measured before dilatation and at postdilatation first, second, and fourth hours. Results: The mean pupillary diameter values at postdilatation second and fourth hours were statistically significantly different between the patients with PXS and PXG (P<0.001, for each). Also, there were significant differences between the PXS group and the control group in terms of the mean pupillary diameter values at predilatation and postdilatation at the first hour and postdilatation second hour (
