Abstract
ABSTRACT Background This study aimed to determine the appropriate target intraocular pressure (IOP) for patients newly diagnosed with exfoliation glaucoma. Research design and methods The study followed a prospective cohort of newly diagnosed exfoliation patients for three years. The target IOP was defined using three methods to measure visual field deterioration, mean deviation (MD), visual field index (VFI), and guided progression analysis (GPA). Results Over the three years, the mean deviation (MD) values declined by an average of −3.84 (±2.61) dB, while the visual field index (VFI) values dropped by an average of 9.66 (±6.25) %. The untreated IOP at inclusion was 32.52 ± 5.54 mmHg. At the end of the study (due to treatment), it was 17.94 ± 1.82 mmHg, resulting in a reduction of 14.58 mmHg (45% reduction). Based on the MD and VFI methods, the target IOP for the whole cohort was around 14–15 mmHg, while the target IOP based on GPA was around 15 mmHg. For advanced glaucoma cases, the target IOP was around 13 mmHg. Conclusions The study concludes that the traditional reported IOP reduction of 20% and/or IOP 18–20 mmHg may not be sufficient for patients newly diagnosed with exfoliation glaucoma. Instead, the study recommends a target IOP of 14–15 mmHg for these patients. Clinical Trial Registration The study was registered in the www.clinicaltrials.gov website with the number NCT06237764.
