Corneal topography of spontaneous perforation of acute hydrops in keratoconus

An unusual case of spontaneous corneal perforation of acute hydrops in the left eye of a 21-year-old man is presented. The patient had a history of atopic diseases. To evaluate the status of the other eye, corneal topographic analysis was performed. This confirmed a subclinical keratoconus in the fellow eye and the association with atopy, eye rubbing, and rapid progression of the ectasia leading to perforation.
