Two-Year Clinical Outcomes of GATT Surgery for Normal-Tension Glaucoma

A 2-year retrospective case series of 9 patients (12 eyes) undergoing gonioscopy-assisted transluminal trabeculotomy (GATT) for normal-tension glaucoma. The data, authored by Zhengfang Wu and last updated in April 2026, includes intraocular pressure, medication burden, and success rates measured at multiple postoperative intervals.

Use Cases

• Analyzing the efficacy of GATT surgery based on intraocular pressure reduction data.
• Evaluating surgical safety profiles based on recorded postoperative events and complication rates.
• Assessing medication burden changes after surgery based on the count of active ingredients.
• Comparing complete and qualified surgical success rates based on strict IOP criteria.

Strengths

• Includes detailed 2-year follow-up data at 7 specific postoperative time points.
• Reports specific statistical results, including a mean IOP reduction of 4.00 mmHg and a 23.1% reduction.
• Contains a sensitivity analysis (one-eye-per-patient) to address potential data dependencies.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Small sample size of 12 eyes from a single-center study.
