Summary

Metabolic disturbances, specifically higher fasting glucose and uric acid levels, are linked to primary open-angle glaucoma (POAG). These findings suggest a role for carbohydrate and uric acid metabolism in POAG pathogenesis.

Area of Science:

  • Ophthalmology
  • Metabolic Medicine

Background:

  • Primary open-angle glaucoma (POAG) pathogenesis is not fully understood.
  • Metabolic diseases are increasingly suspected to influence POAG development.

Purpose of the Study:

  • To investigate the potential role of metabolic disturbances in POAG.
  • To examine specific metabolic parameters in POAG patients.

Main Methods:

  • Serum metabolic parameters were assessed in 49 POAG patients.
  • A control group of 72 age- and sex-matched individuals without glaucoma was included.
  • Fasting serum glucose and uric acid levels were key parameters measured.

Main Results:

  • POAG patients exhibited significantly higher fasting serum glucose (117+/-17 mg/dl) compared to controls (105+/-11 mg/dl, p=0.05).

  • POAG patients also showed significantly higher uric acid levels (6.2+/-1.9 mg/dl) versus controls (5+/-1.2 mg/dl, p=0.006).
  • A greater proportion of POAG patients presented with carbohydrate metabolism disturbances and hyperuricemia.

    • Conclusions:

    • Disturbances in carbohydrate metabolism may contribute to POAG.
    • Elevated uric acid levels are implicated in the pathogenesis of glaucoma.
    • Metabolic dysregulation is a potential factor in POAG development.
