Purpose:
Patients prospectively enrolled in a clinical trial to evaluate the effect of corticosteroid use after guarded filtration procedure (trabeculectomy) were re-evaluated after 10 years to determine whether (1) there were differences in intraocular pressure (IOP) level and stability of glaucoma between treated and nontreated eyes, (2) surgery had altered the clinical course of the patients, and (3) there was any relation between level of IOP and glaucoma control.
Methods:
Forty-six eyes of 35 patients were evaluated individually. Stabilization/ progression of glaucoma was established based on IOP, clinical evaluation of visual fields, and stereoscopic analysis of disc using ophthalmoscopy and photography.
Results:
The nonsteroid-treated eyes underwent more additional glaucoma surgeries, were treated with more glaucoma medicines, and had higher IOPs. Glaucoma was stabilized in 82.8% of the steroid-treated eyes and 67% of the nonsteroid-treated eyes. There was a direct correlation between level of IOP and stabilization of optic nerve and visual field in both groups.
Conclusion:
The use of corticosteroids after guarded filtration procedure was correlated with better glaucoma control. Patients with lower IOPs were more likely to be stabilized than those with higher pressures.
