Association between optic disc haemorrhages in glaucoma and abnormal glucose tolerance
The British Journal of Ophthalmology
|August 1, 1986
Summary
Patients with primary open-angle glaucoma and disc hemorrhages showed higher rates of abnormal glucose tolerance and diabetes. These patients also had lower intraocular pressure compared to those without hemorrhages.
Area of Science:
- Ophthalmology
- Endocrinology
- Glaucoma Research
Background:
- Primary open-angle glaucoma (POAG) is a leading cause of irreversible blindness.
- Disc hemorrhages in POAG are associated with disease progression.
- Glucose metabolism may play a role in glaucoma pathophysiology.
Purpose of the Study:
- To investigate the relationship between disc hemorrhages, glucose tolerance, and intraocular pressure in POAG patients.
- To explore potential links between metabolic health and glaucoma characteristics.
Main Methods:
- Analysis of glucose tolerance test results and intraocular pressure (IOP) measurements.
- Retrospective study of 120 POAG patients over 4-5 years.
- Comparison between patients with (n=62) and without (n=58) recorded disc hemorrhages.
Main Results:
- Patients with disc hemorrhages exhibited a higher incidence of abnormal glucose tolerance or diabetes mellitus.
- Lower mean intraocular pressure levels were observed in patients with disc hemorrhages.
- Disc hemorrhages were associated with distinct metabolic and hemodynamic profiles.
Conclusions:
- Disc hemorrhages in POAG may indicate a subgroup with altered glucose metabolism.
- The association suggests a potential link between diabetes/glucose intolerance and glaucoma, possibly influencing IOP.
- Further research is warranted to elucidate the underlying mechanisms connecting glucose metabolism, IOP, and optic disc events in glaucoma.
