To explore the relative factors of visual field defect in advanced primary glaucoma. A retrospective case-control study. The data of patients with primary advanced glaucoma who had the central 5 to 10 degrees of the visual field or the temporal peripheral field and were treated at Eye & ENT Hospital of Fudan University from January 2014 to December 2019 were reviewed. The patients were divded into the central visual field group and the temporal peripheral field group according to the type of visual field defect. Statistical analyses of single-factor (Chi square test or independent sample test) and multivariate logistic regression were performed to analyze the correlation between the remaining visual field and the risk factors including age, gender, left/right eye, type of glaucoma, baseline glaucoma stage, peak intraocular pressure (IOP), mean IOP, number of operations, family history, high myopia, diabetes, hypertension, hypotension and migraine. A total of 287 patients (287 eyes) were included. There were 101 patients [mean age, (61±15) years; 48 males, 53 females] with the central 5 to 10 degrees of the visual field and 186 patients [mean age, (59±17) years; 107 males, 79 females] with the temporal peripheral field. There was no statistically significant difference between the two groups with respect to age, gender, left/right eye, age of onset, number of operations, family history and history of combined systemic diseases (all >0.05). Primary open-angle glaucoma, chronic primary angle-closure glaucoma (CPACG) and acute primary angle-closure glaucoma were found in 26, 34 and 41 patients, respectively, in the central visual field group, and in 61, 78 and 47 patients, respectively, in the temporal peripheral field group. The baseline glaucoma was in the moderate stage in 30 and 32 patients, and in the advanced stage in 71 and 154 patients, respectively, in the two groups. The peak IOP was (31.94±4.11) mmHg (1 mmHg=0.133 kPa) and (34.58±6.47) mmHg, and the mean IOP was (22.48±3.99) mmHg and (24.01±4.30) mmHg, respectively, in the two groups. High myopia occurred in 5 and 28 patients, respectively, in the two groups. The differences in the type of glaucoma (χ²=7.24), baseline glaucoma stage (χ²=6.04), peak IOP (=4.22), mean IOP (=2.96) and high myopia (χ²=6.57) between the two groups were statistically significant (all <0.05). In the multivariable model, CPACG (=2.021, 95%: 1.020 to 4.001), higher peak IOP (=1.128, 95%: 1.038 to 1.226) and high myopia (=5.090, 95%: 1.556 to 16.651) increased the risks for the progression to the temporal peripheral field. CPACG, higher peak IOP and concurrent high myopia are all relative factors for the progression to the temporal peripheral field in advanced primary glaucoma.
