  • Title: Sterile Corneal Perforation Occurring Several Years After Biliopancreatic Diversion.
    Author: Giannaccare G, Lucisano A, Pellegrini M, Scorcia V.
    Journal: Obes Surg; 2020 Jul; 30(7):2847-2850. PubMed ID: 32144634.
    Abstract:
    BACKGROUND: To report the first two cases of sterile corneal perforation secondary to vitamin A deficiency after biliopancreatic diversion with duodenal switch (BPD/SW). METHODS: Observational case series. RESULTS: Two patients with a history of BPD/SW presented with corneal perforation associated with conjunctival xerosis and keratopathy. In both cases, serum vitamin A level dosage revealed a marked deficit, and the patients admitted poor compliance with vitamin supplementation. Oral therapy with vitamin A was started immediately, and in one case ocular surgery was performed to preserve the integrity of the globe. CONCLUSIONS: Ophthalmologists should carefully examine the ocular surface of patients undergone bariatric surgery in order to promptly recognize the signs of vitamin A deficiency and avoid serious sight-threatening complications.
