Abstract

Background: A prevalent age-related systemic condition called pseudo-exfoliation syndrome (PEX) has severe ocular symptoms like glaucoma and cataracts, Aim: In this study, People with pseudo-exfoliation syndrome (PEX), anterior segment optical coherence tomography (AS-OCT) was utilized to evaluate the anatomical features of the anterior lens capsule and iris.
Patients and Methods: This study was designed as a case-control study at Benha University Hospital, using 20 eyes from 18 patients—2 patients with bilateral PEX and 16 patients with unilateral PEX—and 10 eyes from the normal control group.
Results: The parameters between the new PEX group and the control group were examined and compared using patients with pupillary diameters ranging from 5.5 to 7 mm. Iris thickness (central, ciliary, and pupillary) was considerably lower in the PEX group. Compared to the control group, BCVA was significantly lower in the PEX group.
Conclusion: Our study revealed significant increase thickness of central ALC in PEX group by 11% when compared to control group. Iris thickness (mid-peripheral iris stromal thickness, iris thickness at the papillary border, iris thickness at the ciliary border) all decreased (by 25%, 37%, 39%) in PEX group when compared to the control group. Iris thickness may be assessed before and after dilatation for more accurate evaluation of iris thickness of PEX.
