The effect of recurrent povidone-iodine usage on conjunctival flora in diabetic patients undergoing intravitreal injections.

Repeated intravitreal injection for diabetic macular edema with application of povidone-iodine 5% in diabetic patients did not lead to a significant change in the percentage of positive conjunctival cultures. Patients with higher HbA1C had a slight, non-statistically significant trend for positive cultures.
