ABSTRACT
PRCIS In this study, in patients with pseudoexfoliation syndrome (PXS) or glaucoma, changes in intraocular pressure (IOP) and pupil size after 1% tropicamide used for pupil dilation, compared with healthy patients were quantitatively demonstrated up to 4 hours after dilation. PURPOSE:
The 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 ANDMETHODS:
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 ( P =0.007, <0.001, respectively). The mean pupillary diameter at all times was statistically significantly different between PXG and control groups ( P <0.001 for each). Significant IOP increases were observed in all groups after dilatation. The mean IOP at predilatation and postdilatation fourth hour was statistically significantly different between PXG and PXS groups ( P =0.042, <0.001, respectively). Whereas the mean IOP at predilatation, postdilatation first hour, postdilatation second hour, and postdilatation fourth hour were statistically significantly different between PXG and control group ( P <0.001 for each).CONCLUSIONS:
Significant IOP increases have been observed in our study with 1% tropicamide in the PXG and PXS groups, with the peak effect at the second hour in the postdilatation period. Furthermore, the mean pupil diameter was found to be significantly lower in PXG patients compared with the control group.
