Inclusion criteria are as follows: intraocular pressure (IOP) 22 to 32 mmHg (either eye); normal baseline VF test, defined as Glaucoma Hemifield Test (GHT) “within normal range” in a reliable VF test; at least 2 VF tests in total; no significant ocular comorbidities.</div></div><div><h3>Methods</h3><div>Risk factors are as follows: age, ethnicity, sex, IOP, vertical cup-to-disc ratio, central corneal thickness, VF pattern standard deviation, family history of glaucoma, systemic hypertension, diabetes mellitus, and glaucoma treatment. Glaucoma conversion was defined as 2 consecutive and reliable VF tests with GHT “outside normal limits” and/or need for glaucoma surgery. For validation, the OHTS-EGPS model was applied to predict a patient’s risk of developing glaucoma in 5 years. In the updating stage, the OHTS model was refitted by re-estimating the baseline hazard and regression coefficients.

A total of 1530 (16.9%) patients converted to glaucoma during this follow-up period. The OHTS-EGPS model provided a pooled c-index of 0.61 (95% confidence interval: 0.60–0.63), ranging from 0.55 to 0.67 between hospitals. The pooled calibration slope was 0.45 (0.38–0.51), ranging from 0.25 to 0.64 among hospitals.

The inclusion criteria focused on SRs investigating risk factors for POAG. We registered the study prospectively in the PROSPERO database (CRD42022351372) and used Covidence and the Risk of Bias in Systematic Reviews tool to manage article selection and assess the risk of bias in the included SRs.

In our study, we identified 22 risk factors associated with POAG. The SRs covered a wide range of risk factors for POAG. Among these, the strongest associations with POAG, based on effect size, were observed in 2 SRs related to obstructive sleep apnea (OSA), with a pooled odds ratio (OR) of 3.66 (95% confidence interval [CI]: 1.70–7.90) and an adjusted OR of 2.46 (95% CI: 1.32–4.59).
