Senile disciform macular degeneration and smoking
Summary
Smoking accelerates blindness in patients with senile disciform degeneration. Current smokers experienced blindness onset at age 64, significantly earlier than non-smokers (age 71). Quitting smoking is strongly advised for these patients.
Area of Science:
- Ophthalmology
- Public Health
Background:
- Senile disciform degeneration of the macula is a leading cause of vision loss in older adults.
- Smoking is a known risk factor for various ocular diseases.
Purpose of the Study:
- To investigate the relationship between smoking habits and the age of onset of blindness in patients with senile disciform degeneration of the macula.
Main Methods:
- A cohort of 114 patients diagnosed with senile disciform degeneration of the macula was studied.
- Smoking status (current smoker, never smoked) was recorded.
- The mean age at the onset of blindness in the first affected eye was compared between smoking groups.
Main Results:
- The mean age at onset of blindness was significantly lower in current smokers (64 years) compared to those who had never smoked (71 years).
- This indicates an earlier onset of severe vision loss associated with smoking in this patient group.
Conclusions:
- Smoking appears to accelerate the progression of senile disciform degeneration, leading to earlier blindness.
- Patients diagnosed with disciform degeneration should be strongly advised to cease smoking to potentially delay vision loss.
