A retrospective study to assess visual field improvement following augmented trabeculectomy

Area of Science:

• Ophthalmology
• Glaucoma Research
• Surgical Outcomes

Background:

• Glaucoma management often requires interventions to control intraocular pressure (IOP) and preserve visual fields (VF).
• Augmented trabeculectomy is a surgical option for refractory glaucoma, aiming to reduce IOP.
• Long-term visual field outcomes following this procedure require further investigation.

Purpose of the Study:

• To evaluate visual field (VF) changes two years after augmented trabeculectomy.
• To assess the efficacy of augmented trabeculectomy in controlling intraocular pressure (IOP) and maintaining VF over time.

Main Methods:

• Retrospective study of 206 eyes undergoing augmented trabeculectomy with mitomycin C.
• Inclusion criteria: minimum of two years postoperative follow-up.
• Data collected: baseline characteristics, IOP, VF, glaucoma medications, and complications.

Main Results:

• Mean IOP reduced by 50.2% (22.7 to 10.4 mmHg) post-surgery (P < 0.001).
• Visual field outcomes: 37.4% stable, 17.0% improved, 45.6% deteriorated.
• 84.5% of patients were medication-free post-surgery; higher IOP correlated with VF deterioration (P < 0.001).

Conclusions:

• Augmented trabeculectomy is effective in lowering IOP and stabilizing or improving visual fields in glaucoma patients.
• Early surgical intervention is advised to prevent progressive VF loss.
• Maintaining VF is crucial for driving ability and overall quality of life.
