Retinal structure in vitamin A deficiency as explored with multimodal imaging

Abstract

Purpose To define the retinal structural abnormalities in a patient with vitamin A deficiency. Methods The patient had a complete ophthalmic examination, electroretinography (ERG), short-wave fundus autofluorescence (SW-AF) and spectral domain optical coherence tomography (SD-OCT) imaging. Serum vitamin A levels were measured. Results A 63-year-old man with alcoholic cirrhosis, sclerosing cholangitis and chronic pancreatitis experienced blurred vision and nyctalopia for over a year. There was no family history of eye disorders or consanguinity. His best-corrected visual acuity was 20/20 in each eye; color vision as determined with Ishihara color plates was normal in each eye. Anterior segment examination was unremarkable. He was pseudophakic in both eyes. Standard ERGs showed non-detectable rod function, a cone-mediated dark-adapted response to the standard flash and borderline reduced cone function. Serum vitamin A levels were below 0.06 mg/L (normal 0.3-1.2 mg/L). Fundus examination revealed numerous round yellow-white lesions along the superior arcade and nasal to the optic nerve in both eyes. These lesions were hypoautofluorescent on SW-AF. SD-OCT cross sections demonstrated that they were focal disruptions distal to the ellipsoid band of the photoreceptors with hyperreflective images bulging up the ellipsoid and region. The retinal pigment epithelium and the inner retina appeared intact. Limited and gradual vitamin A supplementation for over a month (20 000 IU/day) led to a dramatic improvement in retinal function and to the resolution of the symptoms. The retinal lesions remained unchanged. Conclusions Imaging of this patient with nyctalopia and severe rod dysfunction suggests that the retinal white lesions known to occur in vitamin A deficiency localize to the photoreceptor layer, particularly the outer segment. On OCT, they are reminiscent of lesions observed in genetic diseases with retinoid cycle dysfunction and of drusenoid subretinal deposits, an abnormality commonly associated with age-related macular degeneration.

  • 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].”

  • 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.”

  • 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].”

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.
