Summary
Lowering intraocular pressure (IOP) can help prevent the progression of exfoliation glaucoma. However, reduced IOP does not guarantee the prevention of disease worsening in all patients.
Area of Science:
- Ophthalmology
- Glaucoma Research
Background:
- Exfoliation glaucoma is a common subtype of secondary open-angle glaucoma.
- Intraocular pressure (IOP) is a primary risk factor for glaucoma progression.
Purpose of the Study:
- To investigate the long-term impact of intraocular pressure (IOP) reduction on disease stability in patients diagnosed with exfoliation glaucoma.
Main Methods:
- A retrospective analysis of medical records from 167 patients across multiple centers.
- Patients were categorized into stable (n=85) and progressed (n=82) groups with a minimum 5-year follow-up.
Main Results:
- Patients who progressed had significantly higher mean IOP (20.1 mmHg) compared to stable patients (18.1 mmHg).
- Higher IOP levels correlated with increased progression rates: 28% at ≤17 mmHg, 43% at 18-19 mmHg, and 70% at ≥20 mmHg.
- Progressed patients showed greater baseline optic disc damage and required more treatment modifications.
Conclusions:
- Intraocular pressure (IOP) reduction is associated with a reduced risk of progression in exfoliation glaucoma.
- While beneficial, IOP reduction does not ensure complete prevention of disease worsening.
