Vitamin A deficiency retinopathy in the setting of celiac disease and liver fibrosis.

This case represents the classic findings of vitamin A deficiency retinopathy on fundus examination and electrophysiologic testing secondary to gastrointestinal pathology and Prompt treatment of high dose vitamin A supplementation led to improvement of full-field and multifocal ERG results, as well as reconstitution of outer retinal architecture.

Electrophysiological assessment of nutritional optic neuropathy: a case report

The findings highlight the value of electrodiagnostic testing alongside imaging in complex nutritional optic neuropathies to help monitor, guide treatment and preserve remaining sight in a child.

Vitamin A deficiency retinopathy related to medical interventions in a Swiss cohort: a case series.

Vitamin A deficiency retinopathy can occur following medical interventions associated with malabsorption secondary to medical interventions, and in cases of night blindness, vitamin A levels should be measured.

Retinal structure in vitamin A deficiency as explored with multimodal imaging

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.

Treatment of vitamin A deficiency retinopathy with sublingual vitamin A palmitate

After 5 months of treatment with sublingual vitamin A drops, the patient’s vision, ERG, mfERG, dark adaptometry, and perimetry normalized, and sublingually vitamin A may represent a viable and efficacious treatment modality for vitamin A deficiency.

Electrophysiological and microperimetry changes in vitamin A deficiency retinopathy

This case illustrates the importance of electrophysiological investigation in early VAD-related retinopathy detection correlated with microperimetry and indicates a more delayed central cone function recovery than that of generalised rod and cone function.

Fundus white spots and acquired night blindness due to vitamin A deficiency

A 61-year-old man with vitamin A deficiency who had previously undergone gastric bypass surgery was observed to have numerous white spots in the retina of each eye, and both rod and cone functions markedly improved after initiation of vitamin A therapy.

Recurrent episodes of night blindness in a patient with short bowel syndrome

Clinical characteristics in a patient with recurrent episodes of night blindness due to vitamin A deficiency caused by short bowel syndrome in Crohn disease and parenteral vitamin A substitution are described, finding ERG might be more sensitive than serum vitamin A level and is recommended in case of day blindness but still normal vitamin Alevel.

VITAMIN A DEFICIENCY MONITORED BY QUANTITATIVE SHORT WAVELENGTH FUNDUS AUTOFLUORESCENCE IN A CASE OF BARIATRIC SURGERY

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.
