Long-Term Visual Field Outcomes in Eyes with Failed Trabeculectomy: Evaluating Repeat Trabeculectomy versus Ahmed Glaucoma Valve Implantation

Long-Term Visual Field Outcomes in Eyes with Failed Trabeculectomy: Evaluating Repeat Trabeculectomy versus Ahmed Glaucoma Valve Implantation

This retrospective cohort study compares visual field progression after repeat trabeculectomy versus Ahmed glaucoma valve implantation in eyes with prior trabeculectomy failure, revealing similar postoperative visual outcomes but greater intraocular pressure reduction with repeat trabeculectomy.
