Diagnostic value of macular ganglion cell complex and thickness and visual field of peripapillary retinal nerve fiber layer on neovascular glaucoma
Abstract
AIM: To analyze the diagnostic value of macular ganglion cell complex(mGCC)and thickness and visual field of peripapillary retinal nerve fiber layer(pRNFL)on neovascular glaucoma(NVG).METHODS: Retrospective study. A total of 92 patients(100 eyes)with NVG who were admitted to our hospital from January 2018 to October 2021 were selected. They were divided into 31 cases(32 eyes)with early NVG, 31 cases(36 eyes)with open angle glaucoma and 30 cases(32 eyes)with angle-closure glaucoma according to their pathology and term. Additionally, 50 cases(100 eyes)receiving health examination in our hospital at the same period were selected as the control group. Pearson correlation was used to analyze the correlation among mGCC, pRNFL thickness and mean deviation(MD), and the diagnostic efficiency of each index was studied by the receiver operating characteristic(ROC)curve.RESULTS: The levels of mGCC-average(a), mGCC-superior(s)and mGCC-inferior(i)in the patients with early NVG, open-angle glaucoma and angle-closure glaucoma were lower than those in the control group(all P<0.001). The levels of mGCC-a, mGCC-s and mGCC-i in the patients with early NVG and the open-angle glaucoma group were higher than those in the angle-closure glaucoma group(all P<0.001). The levels of mGCC-a, mGCC-s and mGCC-i in the patients with early NVG were higher than patients with open-angle glaucoma group(all P<0.001). The thickness of pRNFL-a, pRNFL-temporal(t), pRNFL-s, pRNFL-nasal(n), and pRNFL-i in the patients with early NVG, open-angle glaucoma and angle-closure glaucoma was lower than that in the control group, while the MD was higher than that in the control group(all P<0.001). The thickness of pRNFL-a, pRNFL-t, pRNFL-s, pRNFL-n and pRNFL-i in the patients with early NVG and the open-angle glaucoma was higher than that of patients with angle-closure glaucoma group, while the MD level was higher than that in the patients with angle-closure glaucoma(all P<0.001). The thickness of pRNFL-a, pRNFL-t, pRNFL-s, pRNFL-n and pRNFL-i in the patients with early NVG was higher than that in the patients with open-angle glaucoma, while the MD level was higher than that those with open-angle glaucoma(all P<0.001). The mGCC-a, mGCC-s, mGCC-i, and the thickness of pRNFL-a, pRNFL-t, pRNFL-s, pRNFL-n, and pRNFL-i had a negative correlation with MD(all P<0.001). The combined diagnosis of mGCC, pRNFL thickness and MD had the highest efficiency in NVG(sensitivity: 79.00%, specificity: 87.00, AUC=0.973, 95%CI=0.956-0.990, P<0.05).CONCLUSION: The mGCC and thickness of pRNFL in patients with NVG had a negative correlation with MD. mGCC, pRNFL thickness and MD have a certain diagnostic value on NVG, and the efficiency of combined diagnosis is the highest.
