Summary

Bilateral blindness from open-angle glaucoma (OAG) was uncommon in treated patients. Worse visual field loss at diagnosis and noncompliance with treatment were key risk factors for developing blindness.

Area of Science:

  • Ophthalmology
  • Glaucoma Research
  • Vision Science

Background:

  • Open-angle glaucoma (OAG) is a leading cause of irreversible blindness.
  • Understanding risk factors for blindness in treated OAG patients is crucial for effective management.

Discussion:

  • This study retrospectively analyzed 186 patients treated for OAG.
  • Kaplan-Meier survival analysis estimated blindness risk, while various statistical tests identified risk factors.
  • Blindness was defined by visual acuity and visual field constriction.

Key Insights:

  • Bilateral blindness from OAG was uncommon (6.4% at 15 years) in this cohort diagnosed post-1975.
  • Worse initial visual field loss (P < 0.0001) and noncompliance with treatment (P = 0.016) were significant predictors of blindness.
  • Nonwhite race was also associated with blindness (P = 0.014) when considering all cases.

Outlook:

  • Early detection and consistent treatment adherence are vital for preventing OAG-related blindness.
  • Further research may explore ethnic disparities and personalized treatment strategies.
  • Improved patient education on treatment compliance can mitigate blindness risk.
