—In regard to the article by Margulies and Mannis1 in the October Archives, the authors should be congratulated for describing a new nonherpetic etiology for dendritic corneal lesions.However, in their discussion of the differential diagnosis of a dendritic corneal lesion, the authors failed to mention the healing corneal abrasion, which I have found to be the most frequent cause of dendriform corneal staining. Following a corneal abrasion, the remaining epithelium heals by both migration and mitosis to cover the defect. When the advancing fronts of the sliding epithelium meet, staining will be seen until the epithelium totally joins together. The diagnosis is usually not difficult when a history of previous corneal trauma is apparent. Occasionally, however, a patient will have pain and redness with no obvious history of corneal trauma. These lesions tend to be finer and flatter than herpetic lesions, and they typically have only
