Abstract
This study aimed to assess Leizumab's effect on serum endothelial growth factor, interleukin-6 (IL-6), monocyte chemotactic protein-1 (MCP-1), and inflammatory factors in neovascular glaucoma patients. 80 eligible patients treated between January 2021 and April 2023 were enrolled, randomly divided into control and study groups. The control group underwent vitrectomy while the study group received preoperative intravitreal rituximab injection. Measurements included serum and aqueous humor VEGF/PEDF, IL-6/MCP-1 levels, postoperative rebleeding/retinal detachment, and visual acuity changes over 6 weeks. After surgery, patients showed reduced serum VEGF/PEDF levels (P < 0.05), with decreased VEGF and increased PEDF in aqueous humor (P < 0.05). The study group had lower VEGF and higher PEDF levels than the control (P < 0.05). Serum IL-6/MCP-1 levels reduced post-surgery, with the study group lower than control (P < 0.05). Intraocular rebleeding was lower in the study group (P < 0.05), while retinal detachment rates were similar (P > 0.05). Visual acuity differed significantly from week 1 to 6 post-surgery (P < 0.05), with higher acuity in the study group during weeks 1-4 (P < 0.05). Weeks 5-6 follow-up showed no significant difference (P > 0.05). Pre-vitrectomy ranibizumab injection effectively reduced bleeding, VEGF/PEDF levels, inflammatory factors, and improved visual recovery.
