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.

ABSTRACT

?AIM: To observe the clinical curative effect of the intravitreal injection of anti-VEGF antibody combined with the implantation of Ex-press glaucoma drainage device for neovascular glaucoma ( NG) .?METHODS:A retrospective analysis of 20 patients with NG, who got the intravitreal injection of anti -VEGF antibody combined with the implantation of Ex-press. The visual acuity, intraocular pressure ( IOP ) , iris neovascularization fade and intraoperative and postoperative complications were observed at 1wk, 1, 3 and 6mo postoperatively.?RESULTS:The average IOPs of 20 patients were 47 ± 5.6mmHg, 13.4 ±3.6mmHg, 15.3 ±4.2mmHg, 16.9 ± 5.3mmHg and 18.7 ±6.9mmHg preoperatively and postoperatively 1wk, 1mo, 3mo and 6mo with statistical difference (P<0.05).The intraoperative and postoperative complications of the implantation of Ex-press mainly included early shallow anterior chamber, drainage tube obstruction, filtering bleb scarring. There were 8 eyes with filtering bleb scarring with normal IOP.?CONCLUSION: The intravitreal injection of anti-VEGF antibody combined with implantation of Ex -press is effective for NG, which can significantly reduce the IOP.

ABSTRACT

Glaucoma is a group of diseases which can threaten and damage the optic nerve and its visual pathway, leading to visual impairment as a result. Glaucomatous optic neuropathy is a chronic disease accompanied by apoptosis of retinal ganglion cells ( RGCs ) , visual field defect and cupping of optic nerve head. The gold standard in functional glaucoma evaluation is standard automated perimetry ( SAP) , but it is often limited to the subjective feelings of the patients. Still, visual electrophysiological techniques cannot replace the conventional inspection, but with its rapid development, it has provided a new strategy for the early diagnosis of glaucoma as a supplement because it can show changes in amplitude and latency before visual field defect. Here we review three special electroretinograms and multifocal focal visually evoked potentials in the early diagnosis of glaucoma.
