Vitamin D deficiency is a condition that has been associated with diabetic retinopathy, an eye disease caused by high glucose (sugar) levels. This trial, executed by American and Indian researchers, aimed to evaluate the association of vitamin D levels with the presence and severity of diabetic retinopathy among Indians with type 2 diabetes. The participants underwent various (eye) examinations, and vitamin D levels were measured. Significant lower vitamin D levels were found in patients with retinopathy compared to those without this condition. Additionally, lower vitamin D levels (and vitamin D deficiency) were associated with increased diabetic retinopathy severity. Vitamin D deficiency was also associated with a two-fold increased risk for diabetic retinopathy. More details can be found in the study.
