摘要

Purpose

Minimally invasive glaucoma surgery (MIGS) techniques have become increasingly popular due to their favorable safety profiles compared to traditional glaucoma procedures. Among these, gonioscopy-assisted transluminal trabeculotomy (GATT) has gained prominence in recent years. This study aimed to perform a comprehensive bibliometric and altmetric analysis of GATT-related literature published between 2014 and 2024, with comparisons to other major MIGS techniques.

Methods

A systematic search was conducted in the Web of Science Core Collection database for publications dated between January 1, 2014, and December 31, 2024, despite the data retrieval being performed on May 18, 2025. Boolean search strategies were applied to identify publications related to five MIGS procedures. VOSviewer software (version 1.6.20) was used for network visualization analyses. Citation counts and Altmetric Attention Scores (AAS) were compared between GATT and other MIGS groups.

Results

A total of 1,123 publications were identified, including 149 related to GATT. GATT demonstrated a sharp increase in publication volume after 2018, peaking in 2024. The mean total citation count for GATT publications was 14.75 ± 35.1, and the mean AAS was 2.01 ± 6.05. Although GATT had a significantly lower AAS compared to Hydrus (8.57 ± 20.4, p = 0.008) and iStent (5.89 ± 16.9, p = 0.002), its total citation count was not statistically significantly different from other MIGS techniques (p = 0.06). The top-cited GATT-specific publication was Grover’s 2014 technique report (254 citations; Journal Impact Factor [JIF]: 13.2; Journal Citation Indicator [JCI]: 5.16), while the highest overall citation belonged to Richter’s 2016 review on MIGS (276 citations; AAS: 65). Bibliometric mapping revealed that GATT-related keywords were centrally located and highly interconnected. Authors such as Davinder Grover and Zeynep Aktas were among the most influential contributors in the GATT literature.

Conclusion

GATT has emerged as a widely discussed and increasingly studied MIGS technique in the academic literature over the past decade. Nonetheless, bibliometric and altmetric metrics should be interpreted as reflections of scholarly attention rather than standalone indicators of scientific validity or clinical efficacy.
