Abstract
PURPOSE: To study the clinical profile of pseudoexfoliation (PEX) syndrome in a hospital setting. MATERIALS AND METHODS: A case series of patients with PEX, with and without glaucoma attending the general ophthalmology clinic of a tertiary care center in South India. All patients underwent a complete ophthalmologic evaluation including recording diurnal variation of tension (DVT), gonioscopy and visual field assessment. RESULTS: The study cohort comprised 529 patients (752 eyes). There were 296 (56%) females. The highest number of patients (261 patients) was from the age group between 60 and 69 years. Of 752 eyes, 57.8% eyes had unilateral PEX and 72% had established PEX. Gonioscopy showed open angles in 98.1% of eyes. Intraocular pressure (IOP) greater than 21 mmHg in at least 1 of 4 measurements was recorded in 5.7% eyes. DVT was normal in 96.4% of unilateral PEX eyes, similar to fellow non-PEX eyes. Pseudoexfoliation glaucoma occurred in 1.9% of eyes and 4.7% of eyes were glaucoma suspects. There was no correlation between the stage of PEX and increased IOP. Mean central corneal thickness of PEX eyes was 522 ± 27μ. Pupillary dilatation in 90.5% eyes with early PEX was ≥ 7 mm. CONCLUSIONS: A small percentage of PEX eyes had raised IOP, and the number of eyes with glaucomatous optic neuropathy was even lower. PEX eyes did not demonstrate wide fluctuations in IOP. No correlation was found between raised IOP and stage of PEX. There was good pupillary dilatation in early stage PEX eyes suggesting that all PEX eyes may not have poor pupillary dilatation and related complications.
