An emaciated alcoholic 52-year-old white woman presented with an old left corneal perforation and bilateral conjunctival and corneal xerosis. The serum vitamin A level was 0 mumol/L. Laboratory and radiologic findings were consistent with the diagnosis of a fat malabsorptive syndrome secondary to chronic alcoholic pancreatitis. Histopathologic evaluation of her enucleated globe revealed conjunctival epidermidalization, corneal perforation with prolapse and loss of intraocular contents, retinal detachment, and massive choroidal hemorrhage. A second patient presented with bilateral conjunctival xerosis, corneal ulcers, and a low serum vitamin A level. Corneal perforation of one ulcer ensued during her hospitalization. Medical investigation revealed hepatic metastases of an unknown primary source. Causes of vitamin A deficiency and its ocular complications as well as medical and surgical management options are discussed.

Corneal perforation may be associated with prolapse of ocular tissue and requires prompt diagnosis and treatment. Although infectious keratitis is an important cause, corneal xerosis and collagen vascular diseases should be considered in the differential diagnosis, especially in cases that do not respond to conventional medical therapy. Although medical therapy is a useful adjunct, a surgical approach is required for most corneal perforations. Depending on the size and location of the corneal perforation, treatment options include gluing, amniotic membrane transplantation, and corneal transplantation.
