Abstract
The purpose of this study is to evaluate anterior chamber aqueous flare (ACAF) in Tunisian patients with pseudoexfoliation (PEX) syndrome with or without associated glaucoma. This is a prospective, cross-sectional, comparative study including 53 patients (88 eyes) with PEX syndrome, 48 patients with PEX glaucoma (86 eyes), and 53 healthy sex-and age-matched control subjects (106 eyes). All patients underwent a complete ophthalmic examination and laser flare photometry. Mean ACAF was significantly higher in the PEX syndrome group in comparison with the control group (17.96 ± 10.05 vs 7.06 ± 2.95 ph/ms; p = 10−4), in patients with PEX glaucoma compared to PEX syndrome without associated glaucoma (27.99 ± 15.45 vs 17.96 ± 10.05 ph/ms; p = 10−4), in the PEX glaucoma group in comparison with control group (27.99 ± 15.45 vs 7.06 ± 2.95 ph/ms; p = 10−4), and in patients with unilateral PEX syndrome in comparison with contralateral-unaffected eyes (25.72 ± 14.88 vs 8.58 ± 3.45 ph/ms; p = 0.000). For patients with PEX syndrome, a high ACAF might be a predictor for the development of glaucoma. Further investigations are needed to clarify the role of laser flare photometry in predicting the risk of glaucoma in patients with PEX syndrome.
