Materials and Methods: We examined 60 eyes of 60 patients, 30 of them with PES and 30 without pseudoexfoliation. IOP was measured with Goldmann Aplanation Tonometry before dilation and hourly for four consecutive hours after dilation with tropicamide 1% and phenylephrine 2.5% eyedrops in all patients. Pigment dispersion into the anterior chamber was classified by the same examiner.
Results: Gender, age, central cornea thickness and IOP before dilatation measurements of the groups were similar. IOP measurements after dilatation were statistically significant ,both in the PES group and the control group (p<0.000, p=0.002; respectively). When two groups were compared in terms of IOP change; IOP 1., 2., and 3 hours after dilatation were statistically significant. A significant correlation was found in the PES group's IOP change and first hour anterior chamber pigment intensity, and patients with pigment dispersion in the PES group all had significant IOP rise. While the PES group had a peak IOP in the 2. Hour; IOP of the control group increased progressively in 4 hours.
Conclusion: The effect on pupil dilatation in IOP must be noticed and it should be considered that pigment intensity of the anterior chamber during the first hour of dilatation can be an indicator of IOP rise in patients with PES.
