Abstract Purpose To compare the surgical efficacy and safety of partial and complete gonioscopy‐assisted transluminal trabeculotomy (GATT) in open‐angle glaucoma. Methods This retrospective comparative study included 206 eyes with primary open‐angle glaucoma (POAG) or pseudoexfoliation glaucoma (PEXG) who underwent partial GATT (superior 180°, inferior 180°, or 270°) or complete GATT (360°) at a tertiary centre with at least 12 months of follow‐up. Surgical success (qualified and complete) was defined across three intraocular pressure (IOP) criteria: A ( 0.05). EVFW extent and safety profiles were similar across groups. Conclusion Partial GATT (superior 180°, inferior 180°, or 270°) provides similar surgical outcomes and safety as complete 360° GATT. Hemi‐GATT may serve as a time‐efficient and effective alternative to circumferential GATT in appropriate patients.
