PATTERN OF LONG-TERM INTRAOCULAR PRESSURE VARIATION FOLLOWING GONIOSCOPY-ASSISTED TRANSLUMINAL TRABECULOTOMY WITH AND WITHOUT CATARACT EXTRACTION: TWO-YEAR OUTCOMES.

Objetivo

To assess and compare the impact of gonioscopy-assisted transluminal trabeculotomy, as a standalone procedure (GATT) or combined with phacoemulsification and intraocular lens implantation (PHACOGATT), as primary surgical options, on long-term intraocular pressure (IOP) variation parameters in eyes with clinically uncontrolled glaucoma.

Método

Unicentric retrospective study. Consecutive patients that had undergone GATT or PHACOGATT due to clinically uncontrolled open-angle glaucoma, with at least 24 months of follow-up.

Resultados

A total of 169 eyes were included (GATT = 101 patients; PHACOGATT = 68 patients). Long-term mean IOP (11.2 ± 2.0 mmHg vs 12.0 ± 1.8; p = 0.01) and mean long-term IOP peak (11.8 ± 3.5 mmHg vs 12.9 ± 2.6; p = 0.03) were lower in the PHACOGATT group when compared to the standalone GATT group, while no significant difference was found in mean IOP fluctuation between groups (1.2 ± 1.8 mmHg vs 1.0 ± 3.7 mmHg; p= 0.54).

Conclusões

Patients with clinically uncontrolled open-angle glaucoma submitted to GATT or PHACOGATT surgeries not only achieved low mean IOPs, but also demonstrated stable IOP patterns during a 24-month follow-up period. Our results provide additional evidence supporting GATT and PHACOGATT as viable options for the treatment of medically uncontrolled glaucoma patients requiring low and stable IOPs.
