Trabeculectomy Slows Visual Field Loss Better Than Medication in Advanced Glaucoma

Managing patients with advanced open-angle glaucoma presents a significant clinical challenge, as late diagnosis is frequently associated with lower socioeconomic status and severe functional impairment at presentation [1, 2]. While topical medications and laser trabeculoplasty (a procedure using light energy to improve aqueous humor outflow) are standard for early disease, advanced cases often require incisional surgery to achieve the low intraocular pressures necessary to arrest disease progression [3, 4]. Primary trabeculectomy, a surgical intervention that creates a new drainage pathway for fluid, is often utilized to preserve visual function in these high-risk individuals [5]. However, the extent to which slowing the rate of visual field loss translates into measurable improvements in patient-reported quality of life remains a subject of ongoing clinical investigation [6]. A recent multicenter trial now clarifies the long-term comparative effectiveness of these management strategies, revealing a complex relationship between objective perimetric stability and subjective patient function.
