Inverted T trab PCG

Details and patient eligibility

About

This study aims to evaluate the safety and efficacy of novel Inverted T trabeculectomy in Primary Congenital Glaucoma (PCG). It enrolled 50 eyes of 25 children with PCG. The mean age at the time of surgery was 12±11 months, and the mean presenting IOP was 40±4 mmHg. Patients with previous intra-ocular or conjunctival surgery, those who had significant ocular trauma, and patients with congenital glaucoma associated with ocular anomalies diseases were excluded from the study. All patients had Inverted T trabeculectomy under general anesthesia. The IOP in the operated eyes was followed up for 36 months.

Full description

This study included patients from the glaucoma clinic at Benha University Hospital between April 2015 and October 2017. All were diagnosed with PCG based on an intraocular pressure (IOP) measurement of 21 mmHg or more at birth or shortly after, up to the age of 12 months. Patients with previous intraocular or conjunctival surgery, those with significant ocular trauma, and those with congenital glaucoma associated with other ocular anomalies that would affect IOP were excluded from the study.

The procedure principles and potential complications were discussed with the children's parents or legal guardians, and they gave written informed consent before surgery. This study was approved by the Benha Faculty of Medicine's ethical committee (Approval number RC 9-1-2025) and conducted according to Helsinki's declaration.

All patients underwent complete ophthalmic examination under general anaesthesia before surgery. IOP was measured 5 minutes after injecting intravenous Ketamine 1mg/kg for induction of anaesthesia. We used a Perkins tonometer (Haag-Streit, UK) to measure the IOP before applying the eyelid speculum. Corneal clarity was assessed under a surgical microscope, the corneal diameter was recorded using a surgical caliber, and fundus examination was done by indirect ophthalmoscope. A surgical Swan Jacob gonioprism assessed the anterior chamber angle when the cornea was clear enough to achieve a good view.

All surgeries were performed under general anaesthesia by the same surgeon (AEH).
