Expressions of inflammatory factors of aqueous humor before the surgery of chronic primary angle-closure glaucoma and its influence on prognosis
Abstract
AIM: To investigate the expression level of inflammatory factors of aqueous humor before trabeculectomy in binocular chronic primary angle-closure glaucoma(CPACG)and its correlation with postoperative filtration bleb and intraocular pressure.METHODS: A total of 15 cases(30 eyes)with binocular CPACG who admitted to the Affiliated Eye Hospital of Nanjing Medical University from September to December 2021 and received trabeculectomy were selected. The surgery interval between two eyes was 7d, and the preoperative expression levels of monocyte chemoattractant protein-1(MCP-1), interleukin-17(IL-17), transforming growth factor-β(TGF-β), and interferon-γ(IFN-γ)of the aqueous humor in both eyes were respectively detected by enzyme-linked immunosorbent assay(ELISA). Furthermore, the intraocular pressure(IOP)and the morphology of filtering blebs at 1mo after surgery were measured.RESULTS: The concentrations of MCP-1, IL-17, TGF-β, and IFN-γ in aqueous humor from the first eye before surgery were 330.4±46.2, 357.3±46.9, 2347.5±363.8 and 527.7±101.6pg/mL respectively, and those concentrations in aqueous humor from the fellow eye were 298.2±40.7, 309.1±53.5, 1938.3±426.0 and 628.2±104.9pg/mL respectively. The preoperative expression levels of inflammatory factors of aqueous humor in both eyes were statistically significant(P≤0.05). Furthermore, the expression levels of IL-17 and TGF-β in the aqueous humor of patients with CPACG correlated with IOP and the height of filtering blebs at 1mo after surgery(P<0.05).CONCLUSION: There may be changes in the expression levels of inflammatory factors of aqueous humor in the fellow eye after surgery of the first eye. Moreover, the preoperative expression level of IL-17 and TGF-β in aqueous humor possibly related to postoperative IOP and the height of filtering bleb.
