Abstract :
Introduction: 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.[Case Presentation]The case was a 36yearold 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 longterm followup, changes in topographic parameters happened very slowly.[Conclusions]In conclusion, optical corneal changes should be considered in the ocular surface chemical burn, especially in sectorial involvement despite clear cornea.
