Patients were grouped according to vision outcomes after 1 year of treatment: mild – moderate vision loss (best corrected visual acuity [BCVA] > light perception [LP]) and severe vision loss (BCVA ≤ LP). The associations between patient characteristics and BCVA were also examined.Results: Of the 89 patients (99 eyes), those with progression to severe vision loss presented with higher intraocular pressure (IOP) (p < 0.001) and lower visual acuity (p = 0.003) on average. However, there was no difference in IOP between the vision loss groups after one year of treatment. Univariate analysis showed a moderate association between a history of type 2 diabetes mellitus (T2DM) and severe vision loss (p = 0.033). Increasing age was associated with an increased likelihood of progression to severe vision loss (odds ratio [OR] 1.074, p = 0.008). Females were more likely to exhibit severe vision loss (OR 3.281, p = 0.036). Patients with Medicare (OR 0.098, p = 0.005) or private insurance (OR 0.110, p = 0.006) were less likely to progress to severe vision loss than those without insurance.Conclusion: Progression of vision loss in patients with NVG may be influenced by the stage of disease at diagnosis, age, sex, T2DM, and insurance status.Keywords: glaucoma, vision loss, risk factors, disease progression |
