Older age and male sex are associated with increased risk of visual field loss in primary open-angle glaucoma (POAG) patients on treatment. Further research is needed to refine risk stratification strategies for managing POAG.

Area of Science:

  • Ophthalmology
  • Glaucoma Research
  • Clinical Data Analysis

Background:

  • Primary open-angle glaucoma (POAG) is a leading cause of irreversible blindness.
  • Effective management of POAG requires identifying patients at high risk for progressive visual field loss.
  • Current risk stratification strategies may benefit from incorporating additional clinical factors.

Purpose of the Study:

  • To identify clinically useful risk factors for progressive visual field loss in POAG patients undergoing treatment.
  • To evaluate routine ophthalmic data for predictive value in glaucoma progression.
  • To inform clinical care strategies for managing POAG.

Main Methods:

  • Retrospective cohort study design.
  • Analysis of routine ophthalmic data from 108 POAG patients over an average of 3.6 years.

  • Survival analysis and Cox proportional hazards modeling to assess risk factors for visual field progression.

    • Main Results:

    • The incidence rate of progressive visual field loss was 5.4 per 100 person-years.
    • Increasing age was independently associated with a significantly increased risk of progression (HR 1.07, P=0.022).
    • Male sex showed a borderline association with increased risk (HR 2.76, P=0.057).

    Conclusions:

    • Routine ophthalmic data can provide preliminary insights into risk factors for POAG progression.
    • Age and sex are potential factors influencing visual field loss in treated POAG.
    • Further prospective studies are necessary to validate these findings and improve risk stratification for chronic open-angle glaucoma management.
