ABSTRACT
Exposure keratopathy results from persistent exposure of the ocular surface to the external environment, with drying of the cornea despite normal tear production due to abnormalities in lid closure and blinking mechanism. It results in epithelial breakdown and various complications like infective keratitis, perforation, extensive scarring and even visual loss. The causative factors can be broadly classified as neurological and those occurring as a result of malposition of eyelids; the latter is usually caused by any pathology resulting in either proptosis or lagophthalmos.2 The management of exposure keratopathy revolves around treating the underlying disorder and supportive therapy to prevent ocular damage and secondary complications. Abaxial proptosis with periocular erythema, lid oedema, ptosis and incomplete left-eye closure along with exposed cornea and purulent discharge were evident. The infective keratitis responded to medical management and the ulcer healed, leaving a residual macular corneal opacity, in around six weeks.
