Abstract
Purpose
To evaluate clinical presentation and long-term follow-up of exfoliation glaucoma in separate European population groups.
Methods
A four-center, retrospective, case series analysis in which 200 charts of patients with exfoliation glaucoma or patients with elevated intraocular pressure (IOP) associated with exfoliation syndrome in at least one eye with at least 5 years of follow-up were consecutively reviewed.
Results
This study found an average follow-up time of 6.0±2.1 years. Patients in Hungary and Spain statistically presented at an older age (79 years) than Greek patients (67 years). Patients with exfoliation glaucoma in Greece and Hungary had more glaucomatous damage, had more severe glaucoma, had a higher untreated IOP (31.8 to 32.1 mmHg), and were more difficult to control, showing a greater number of changes in medicines during the follow-up period, a greater number of medicines at the end of the follow-up period, and more progression. On long-term follow-up, Greek, Russian, and Hungarian patients also had the highest mean IOP (18.8 to 20.8 mmHg) and the greatest incidence of progression (approximately 50%). Spanish patients demonstrated the lowest mean IOP (17.6±3.6 mmHg) and the lowest rate of progression (28%) during the follow-up period and the fewest number of medications per patient (0.7) to control the IOP at the end of the follow-up period.
Conclusions
The severity of exfoliation glaucoma presentation and its course may differ within distinct geographic populations in Europe.
