| Summary: | Purpose: To describe our experience of Gonioscopy-Assisted Transluminal Trabeculotomy (GATT) in four eyes with infantile primary congenital glaucoma (PCG). Observations: We report the first two GATT procedures performed in six-month-old infants with PCG. We also report the same procedure in two eyes of a two-year-old boy with PCG who had previous goniotomies with subsequent peripheral anterior synechiae formation. In all four eyes, the IOP remained under 20 mmHg at years three and four postoperatively, without glaucoma medication or conjunctival surgery. Conclusions and importance: Our cases confirm that GATT is an alternative to traditional ab externo glaucoma surgery in PCG and can be successfully performed within the first months of life, or in infants with failed or partially functioning goniotomies, avoiding the need for invasive conjunctival or scleral surgery.
