Senile macular degeneration: a case-control study
American Journal of Epidemiology
|August 1, 1983
Summary
Senile macular degeneration risk is linked to family history, eye color, and cardiovascular disease. While some environmental factors like chemical exposure show associations, genetic and personal traits appear more influential.
Area of Science:
- Ophthalmology
- Epidemiology
- Genetics
Background:
- Senile macular degeneration is a primary cause of vision impairment in the US.
- The disease's etiology is not fully understood, necessitating investigation into contributing factors.
Purpose of the Study:
- To investigate the influence of host and environmental factors on the development of senile macular degeneration.
- To identify specific risk factors associated with this condition.
Main Methods:
- A case-control study involving 162 senile macular degeneration cases and 175 controls.
- Data collected through interviews on medical, occupational, and family history, supplemented by fundus photography validation.
Main Results:
- Significant associations found between senile macular degeneration and family history (OR=2.9), chemical work exposures (OR=4.2), blue/medium eye pigmentation (OR=3.5), cardiovascular disease history (OR=1.7), reduced grip strength, and hyperopia.
- Cigarette smoking showed a significant risk only in males (OR=2.6).
Conclusions:
- Familial, genetic, and personal characteristics are major influences on senile macular degeneration development.
- Further research is required to fully elucidate the role of environmental factors in the disease.
