Recurrent corneal erosion after trauma: a statistical study

Office records of 377 consecutive traumatic corneal abrasions were examined. Twenty-nine cases experienced at least one episode of recurrent corneal erosion (7.69%). There were no recurrences in patients under 20 years of age (P less than .01). The size of the original abrasion could not be correlated with recurrence rate. Injuries with paper, fingernails, or bushes and branches were 4.9 times more likely to recur than injuries from all other materials (P less than .001).
