Ocular Chemical Burn with an Unusual Presentation: A Case Report

Ocular chemical injury is an ophthalmic emergency that may be challenging to manage. Here, we presented a case of persistent corneal astigmatism secondary to chemical burn with superficial limbal injury and no corneal involvement.

The case was a 36-year-old man who presented with a chemical acid injury in the right eye. He had sectorial superficial involvement of inferior limbus from 4 to 5 o’clock hours, and the cornea was clear. Corneal topography showed high irregular astigmatism that was not corrected with glass. In long-term follow-up, changes in topographic parameters happened very slowly.

In conclusion, optical corneal changes should be considered in the ocular surface chemical burn, especially in sectorial involvement despite clear cornea.
