ocular chemical burn with an unusual presentation: a case report

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.
