Baerveldt glaucoma implant surgery was more successful than trabeculectomy in patients with neovascular glaucomaaccording to a new study, the incidence of posopterative complications was similar between both surgical procedures.
Data showed that additional glaucoma surgery was required more often after trabeculectomy than after Barbelt glaucoma implant surgery.
Researchers led by Masaru Inatani, M.D., Ph.D., Department of Ophthalmology and Vision Science, Kumamoto University Graduate School of Medicine, compared the surgical outcomes of Baerveldt glaucoma implant surgery and trabeculectomy with mitomycin C in a patient population. started.
Retrospective clinical cohort study at five Japanese clinical centers that recruited patients treated with trabeculectomy or Baerveldt glaucoma implants for neovascular glaucoma between April 2012 and December 2019. Vision and previous tube shunt surgery.
They noted that if both eyes of the same patient met the inclusion criteria, the first treated eye was investigated. The study included 100 eyes undergoing Baerveldt glaucoma implant surgery and 204 eyes undergoing trabeculectomy.
The primary outcome of the study was surgical success or failure, with failure defined according to three criteria: , or Criterion C (IOP > 14 mmHg). Other failures identified were due to reoperation, loss of light perceptual vision, or hypotonia.
The results show that the probability of success was significantly higher in patients who underwent Baerveldt glaucoma implant surgery than in those who underwent criterion A trabeculotomy (P. <.01) and B (P. = .01).
Trabeculectomy is a Criterion A (Hazard Ratio [HR], 1.70) and criterion B (HR, 1.50). The overall incidence of postoperative complications was similar between the two groups.
In addition, reoperation was required significantly more frequently in the trabecartomy group than in the Baerveldt glaucoma implant surgery group (20.1% vs. 5.0%; P. <.01), according to investigators.
