Reversal of New-Onset Corneal Ectasia Associated With Persistent Eye Rubbing.

INTRODUCTION

Corneal ectasias are progressive diseases that, if untreated, can cause severe vision loss. Among several causes, eye rubbing is increasingly recognized. Many reports link eye rubbing to ectasia development, but few describe the potential for reversal after cessation.

PATIENT AND CLINICAL FINDINGS: A 68-year-old White man presented with subjective eye redness, itchiness, and progressively worsening vision for 5 months. Corneal tomography showed a superior corneal ectasia with central thinning and irregular astigmatism.

DIAGNOSIS, INTERVENTION, AND OUTCOMES: The ectasia was attributed to repetitive mechanical trauma from frequent eye rubbing. Treatment included antihistamine drops, an eyelid scrub for suspected allergic conjunctivitis, and counseling on stopping eye rubbing. At 1 week, symptoms improved; at 1 month, corneal tomography showed significant improvement.

CONCLUSIONS

Early identification of eye rubbing in patients developing corneal ectasia is critical. Stopping the behavior may halt progression and potentially reverse early corneal changes.
