Patient: A 57-year-old patient with diabetes mellitus presented with therapy-resistant superficial punctate keratitis in his only eye. Finally self-injury was suspected. After unsuccessful medical treatment of three weeks' duration the disease could be healed promptly after application of an eyepad: the patient admitted self-manipulation.
Conclusion: In all patients with ocular pathology of uncertain origin, especially in corneal lesions, self-inflicted injury should be part of the diagnostic consideration.
