Corneal Physician Bulletin: Diabetes Mellitus Predisposes Patients to Recurrent Corneal Erosion

            Diabetes mellitus (DM) patients are at higher risk for recurrent corneal erosion (RCE), reports a study in the BMJ.1
            Specifically, 1236 DM patients vs. 884 control patients developed the painful condition. Additionally, in adjusting for potential confounders, such as chronic renal disease, hyperlipidemia, hypertension and keratoconjunctivitis sicca, the researchers discovered DM patients were 1.35 times more likely to develop RCE vs. the entire sample cohort.
            The study was comprised of 239,854 DM patients who were recruited between 2003 and 2005 from the Longitudinal Cohort of Diabetes Patients database. The control patients were number, age and sex-matched and chosen from the Taiwan Longitudinal Health Insurance Database, 2000. 
            The study’s researchers say, “…Close collaboration between endocrinologists and ophthalmologists is important in managing RCE following DM.”
