Primary Angle Closure Glaucoma Clinical Trial
Official title:
Effectiveness and Safety of Trabeculectomy and Peripheral Iridectomy Plus Goniotomy in Advanced Primary Angle-closure Glaucoma: a Multicenter Non-inferiority Randomized Controlled Trial
A multicenter, parallel, open, non-inferior randomized controlled trial is conducted to compare the effectiveness and safety of trabeculectomy and peripheral iridectomy plus goniotomy (TVG) in the treatment of advanced primary angle closure glaucoma with no or mild cataracts.
Primary angle-closure glaucoma (PACG) has a high prevalence and blinding rate in China. The routine first-line treatment of advanced PACG is trabeculectomy, especially in those without cataract. However, due to surgery complications and exhausting post-surgery caring, traditional trabeculectomy is not an ideal choice in clinical practice, particularly in patients with high risk of complications such as younger age and shorter axial length. Peripheral iridectomy (SPI) plus intraocular pressure (IOP)-lowering medications is an alternative. Minimally invasive glaucoma surgery (MIGS) has recently showed its safety and effectiveness in the treatment of PACG, usually combined with cataract surgery, goniosynechialysis (GSL) and goniotomy(GT). The safety and effectiveness of phacoemulsification and intraocular lens implantation (PEI)+GSL+GT in advanced PACG with cataract has been conducted (clinical trials.gov, NCT04878458). It is valuable to explore the safety and efficacy of SPI+GSL+GT in these PACG patients with no or mild cataracts. Therefore, this study intends to conduct a multicenter, non-inferior randomized controlled clinical trial to compare the effectiveness and safety of trabeculectomy versus SPI+GSL+GT in advanced PACG with no or mild cataracts. ;
