Objective To observe the expression levels of related cytokines in the vitreous humor of eyes with rhegmatogenous retinal detachment (RRD) associated with lattice degeneration (LD). Methods A clinical observational study. From May 2022 to February 2023, 43 patients of 43 eyes diagnosed with RRD, with or without accompanying LD, who underwent their first pars plana vitrectomy (PPV) at Zhongda Hospital Southeast University and The Affiliated Eye Hospital of Nanjing Medical University were included in the study. The patients were divided into two groups: RRD with LD (LD group), consisting of 27 patients with 27 eyes, and RRD without LD (Non-LD group), consisting of 16 patients with 16 eyes. Additionally, 6 patients (6 eyes) with idiopathic macular holes and 4 patients (4 eyes) with idiopathic epiretinal membranes during the same period were selected as the control group. Before initiating PPV and without intraocular perfusion, a 0.5 ml sample of undiluted vitreous fluid from the central portion was excised and aspirated. The concentrations of monocyte chemoattractant protein-1 (MCP-1), macrophage inflammatory protein-1 alpha (MIP)-1α, MIP-1β, interferon-γ- inducible protein 10 (IP-10), interleukin-6 (IL-6), IL-8, macrophage migration inhibitory factor (MIF), tumor necrosis factor-alpha-α, interferon-γ, intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule-1, platelet endothelial cell adhesion molecule 1 (PECAM-1), placental growth factor (PLGF) and vascular endothelial growth factor (VEGF) in the vitreous fluid were quantitatively measured using the Luminex high-throughput multiplex assay technology. The comparison of cytokine expression levels between groups was performed using the Kruskal-Wallis rank sum test, with significance levels for post-hoc pairwise comparisons adjusted by DSCF methods. Results The eyes of the patients in the LD group, Non-LD group, and control group showed statistically significant differences (P<0.05) in the concentrations of IL-6 (H=14.400), IL-8 (H=13.610), MCP-1 (H=12.050), VEGF (H=9.920), MIP-1α (H=6.620), IP-10 (H=7.780), MIF (H=12.920), PECAM-1 (H=9.990), ICAM-1 (H=8.070), and PLGF (H=16.850). Upon pairwise comparison between groups, the vitreous fluid concentrations of IL-6, IL-8, and PLGF in the LD group were found to be significantly higher than those in the Non-LD group (P<0.05). Conclusion The expression levels of IL-6, IL-8, and PLGF are elevated in the vitreous fluid of eyes with RRD accompanied by LD.
