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

A 24-month retrospective case series of 9 patients (12 eyes) undergoing gonioscopy-assisted transluminal trabeculotomy (GATT) for normal-tension glaucoma. The dataset, authored by Zhengfang Wu and last updated in April 2026, reports intraocular pressure, medication burden, and surgical success rates at multiple postoperative intervals.

Use Cases

• Analyzing the efficacy of GATT surgery based on reported intraocular pressure reduction and medication burden changes.
• Evaluating surgical safety profiles based on recorded postoperative events and complication rates.
• Modeling surgical success rates based on the defined criteria for complete and qualified success.
• Conducting sensitivity analyses for clinical studies based on the described one-eye-per-patient methodology.

Strengths

• Includes specific clinical metrics: mean IOP reduction of 4.00 ± 2.86 mmHg and a 23.1% reduction from baseline.
• Reports detailed success criteria outcomes: both qualified and complete success rates were 50.0% at 24 months.
• Provides longitudinal data with follow-up at 8 specific time points from day 1 to month 24.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Based on a small, single-center retrospective study of 12 eyes, limiting generalizability.
