Maculopathy increases incidence of cataract surgery in patients with diabetes
Acta Ophthalmol. 2011:89(1):25-29.
Patients with diabetes and maculopathy at baseline had a higher cumulative incidence of cataract surgery after 25 years, according to a study.
A population-based cohort of 562 patients with type 1 diabetes was found to be at greater long-term risk for cataract surgery. All patients lived in Denmark and underwent baseline exam between 1981 and 1982.
In 2006, the 25-year crude cumulative incidence of cataract surgery for the cohort was 20.8% (117 patients). Patients with type 1 diabetes had cataract surgery at an average age of 20 years younger than patients without the disease.
According to multivariate analysis, baseline maculopathy was one of the only risk factors for cataract surgery. Univariate analysis confirmed that patients with maculopathy were more likely to have cataract surgery than patients without maculopathy (30.8% vs. 18.5%; P = .005). The authors suggested further study for this novel finding.
Baseline age was also predictive of cataract surgery, but factors such as gender, blood pressure, smoking and duration of diabetes had no association with cataract surgery incidence, the authors said.
