24-MONTH OUTCOMES OF MODIFIED GONIOSCOPY-ASSISTED TRANSLUMINAL TRABECULOTOMY FOR CONGENITAL GLAUCOMA

Objetivo

To report a case series of primary congenital glaucoma (PCG) patients submitted to modified gonioscopy-assisted transluminal trabeculotomy (GATT) surgery.

Método

This is a retrospective case series about 9 eyes with PCG. Modified GATT was performed in all eyes by the same surgeon along 24 months. The data collected, before and after treatment, were IOP, postoperative complications, such as hyphema and number of eye drops. We also evaluated the extention of treatment, which means the number of quadrants GATT were performed. The IOP values before and after modified GATT, were compared with a paired T-test, with a 95% confidence interval.

Resultado

9 eyes of different patients with PCG underwent modified GATT surgery with a follow-up of 24 months. Surgical interventions were performed on patients aged since 3 months to 10 years (mean 3.9 years). Only 2 patients (22.23%) had not previously been submitted to trabeculotomy and/or goniotomy surgery. GATT was performed in all quadrants in 8 of 9 eyes (88.89%), while 1 eye had only 1 quadrant (90º) treated. Hyphema was a common complication found in 7 of 9 eyes (77.8%). Mean IOP before surgery were 25.89 mmHg [standard deviation (SD) = 4.26]. All patients were in use of at least 3 hypotensive drops (mean of 3.11 drops with a SD of 0.34). 8 patients were in use of 3 hypotensive drugs and 1 patient in use of 4 drugs. The mean IOP after 30 days of surgery was 11.12 mmHg (SD = 1.76), with a mean number of 1.23 hypotensive drops (SD = 0.97). The difference of the mean IOP before and after modified GATT surgery was statistically significant.

Conclusão

In this case series, modified GATT surgery has shown to be efficient and safe in the management of PCG. This tecnique was able to reduce mean IOP and hypotensive drugs in all patients of the study. Adopting a less invasive technique, achieving disease control and reducing the number of drugs, GATT surgery reached its role to improve patient's quality of life.
