OBJECTIVE
To report the clinical and histopathological findings of a patient with bilateral keratomalacia arising from severe vitamin A deficiency from panic disorder-related malnutrition.
METHODS
Case report.
RESULTS
A 47-year-old male with panic disorder presented with 1 month of painful vision loss sequentially affecting the right and left eyes. He exhibited bilateral conjunctival xerosis with complete corneal melt in the right eye and a large corneal epithelial defect with underlying anterior chamber inflammation in the left eye. Laboratory investigation revealed undetectable serum vitamin A levels attributed to self-induced vomiting and starvation. He was treated with high-dose vitamin A, but the right eye required enucleation. The histological findings are reported.
CONCLUSIONS
Vitamin A deficiency in the absence of organic gastrointestinal abnormalities is exceedingly rare in the developed world. A strong index of suspicion and thorough review of systems are invaluable in evaluating patients with unexplained corneal melt.
