Abstract

Background/Purpose: Bariatric surgery is recognized as a treatment option for obesity. However, the cost-efficiency of screening for serum vitamin A and the effectiveness of its oral supplementation in these patients remain unclear. Here, we report a case in which vitamin A and carotenoid deficiency after bariatric surgery were monitored by noninvasive quantitative fundus autofluorescence imaging. Methods: Case report. Results: A 62-year-old man presented with a history of progressive night blindness. He had duodenal switch surgery 13 years earlier. One year before the initial visit, he had begun oral supplements of vitamins A. Short wavelength fundus autofluorescence images acquired for quantitative fundus autofluorescence revealed an intensity that was lower than the healthy-eye range. Scotopic rod-specific full-field electroretinograms were extinguished. These findings were consistent with vitamin A deficiency. The patient was given intramuscular vitamin A injections. At follow-up, quantitative fundus autofluorescence improved, ERG increased to normal, but macular pigment was unchanged. Conclusion: Oral vitamin A supplementation may not be sufficient after mal-absorptive surgery and a quantitative and noninvasive short wavelength fundus autofluorescence imaging technique may be useful to monitor the status of vitamin A and the carotenoids comprising macular pigment in the retina.

  • Vitamin A replacement results in improvement of retinal function as well as structure, but long-term deficiency can lead to permanent degeneration of photoreceptors.

    “Vitamin A replacement results in improvement of retinal function as well as structure, however long-term deficiency can lead to permanent degeneration of photoreceptors [31,80,81,83,84,85,86,87,88,90].”

    From The Role of Vitamin A in Retinal Diseases (2022) · cites this paper as [86]

    The Case Report (page unavailable) describes improved visual acuity and normalized rod ERG responses after vitamin A injections, along with better-defined retinal reflectivity bands on OCT. The paper does not state that long-term vitamin A deficiency causes permanent photoreceptor degeneration; the Discussion instead considers persistent macular pigment deficiency as a possible reason visual acuity did not fully recover.

  • Vitamin A deficiency can be monitored by fundus autofluorescence imaging, which may reveal hypoautofluorescent lesions and decreased autofluorescence signal.

    “Similarly, vitamin A deficiency can be monitored by fundus autofluorescence (FAF) imaging. It may reveal hypoautofluorescent lesions [84,85] and decreased autofluorescence signal [86,87,88].”

    From The Role of Vitamin A in Retinal Diseases (2022) · cites this paper as [86]

  • Vitamin A is needed for normal visual function, and vitamin A deficiency (hypovitaminosis A) results in visual dysfunction that is reversible with vitamin A supplementation.

    “Vitamin A is needed for normal visual function and vitamin A deficiency (hypovitaminosis A) results in visual dysfunction that is reversible with vitamin A supplementation.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
