RESUMO
A 76-y-old Japanese man who had undergone gastrectomy 4.5 y earlier experienced 2 wk of sore throat, heartburn, and difficulty swallowing. Endoscopy showed deep, craterlike, longitudinal ulcers in the lower and middle esophagus. Immunohistochemistry and blood tests were negative for herpes simplex virus and cytomegalovirus infections. The patient reported no other symptoms affecting the gastrointestinal tract. Although his symptoms ameliorated after initial hospitalization and treatment, they re-emerged a few days after being discharged. Fifty-one days after being first admitted, he complained of glossalgia. The serum zinc level was found to be 38 µg/dL, which was below the reference range; the patient was diagnosed with zinc deficiency. After oral zinc administration, the patient was relieved of the symptoms, and his pain was alleviated. Upper gastrointestinal endoscopy after symptom relief showed improvement in the esophageal ulcers. He has continued taking zinc supplementations, and has not developed similar symptoms in the 5 y since being treated. To the best of our knowledge, this is the first case report of esophageal ulcers related to zinc deficiency.

PURPOSE: To investigate the corneal topography and visual function of patients with Mooren ulcer using 3-dimensional anterior segment optical coherence tomography (3-D AS-OCT). METHODS: Fourteen eyes of 9 patients with Mooren ulcer were studied. Pachymetric and axial power maps were obtained by 3-D AS-OCT. The axial power maps were classified into 3 patterns by visual inspection. The distribution of the corneal dioptric power was analyzed by Fourier harmonic expansion. The magnitudes of the spherical component, asymmetry, regular astigmatism, higher-order irregularity, and radial distance from the corneal vertex to the thinnest point of the lesion were determined. RESULTS: The axial power maps of 9 eyes were classified into arcuate patterns, 4 into crab-claw patterns, and 1 eye into an intermediate pattern. The radial distance from the corneal vertex to the thinnest point of the lesion was significantly shorter in the crab-claw pattern group than in the arcuate pattern group (P = 0.007). The magnitudes of asymmetry, regular astigmatism, and higher-order irregularity of the crab-claw pattern group were significantly greater than those of the arcuate pattern group (P = 0.017, P = 0.011, and P = 0.030, respectively). CONCLUSIONS: Three-dimensional AS-OCT is able to evaluate the corneal topography of opacified peripheral lesions in eyes with Mooren ulcer, and the results showed that irregular astigmatism is higher when the lesion is closer to the center of the cornea.
