We report on three boys, of Indian origin, with Dent's disease that presented at an early age (1-4 years), with polyuria, polydipsia, saltcraving, recurrent vitamin A-responsive night blindness, hypophosphataemic rickets, hypercalciuria and low molecular[ncbi.nlm.nih.gov]
The seasonal pattern for nightblindness roughly parallels that for scurvy and for diarrheal diseases. The peak season for nightblindness incidence was summer, and the next highest season was spring.[ncbi.nlm.nih.gov]
Acquired Causes Most of the acquired causes of nightblindness (nightblindness which is not present since birth and does not have a genetic basis), generally fall into the category of progressive nightblindness.[web.archive.org]
Multivariate logistic regression was used to identify socioeconomic, demographic, and pregnancy-related factors associated with maternal nightblindness. RESULTS: Women reported nightblindness in 687 (5.2%) of 13,171 pregnancies.[ncbi.nlm.nih.gov]
RESULTS: The prevalence of gestational nightblindness was 9·9 %.[ncbi.nlm.nih.gov]
The Se concentration was inversely associated with the risk of nightblindness in both genders. These results add to an increasing body of evidence that Se is a protecting element for nightblindness.[ncbi.nlm.nih.gov]

Symptoms include retinopathy, polyneuropathy, ataxia, and deafness. They are variable and rarely recognized before adulthood. The authors report the case of a 14-year-old girl diagnosed because of night blindness.[ncbi.nlm.nih.gov]
The patient had suffered from mental retardation, epilepsy, and mild cerebellar ataxia. Corrected visual acuity was 20/30 in the right eye and 20/25 in the left. Goldmann perimetry showed no scotoma but slight depression with internal isoptors.[ncbi.nlm.nih.gov]

Despite the normal serum vitamin A levels, the patient was instructed to commence treatment with high doses of oral vitamin A supplements.[ncbi.nlm.nih.gov]

Pathogenesis Etiology Inherited in the Appaloosa by, as yet, an unidentified pattern - thought to be either autosomal recessive, or sex-linked recessive, with the defect on the X chromosome.[vetstream.com]
Etiology Oguchi disease is caused by mutations in the SAG gene coding for arrestin located on chromosome 2q37(Oguchi type 1) or by mutations in the GRK1 gene that codes for the rhodopsin kinase located on the chromosome 13q34 (Oguchi type 2).[orpha.net]
It is possible that the downregulation of TRPM1 in the retina of LP/LP horses is the etiology of CSNB. TRPM1 may play a role in neural transmission in the retina through changing cytosolic free Ca 2 levels in the retinal ON bipolar cells.[dx.doi.org]

Proper intake of vitamin A is one preventive measure against night blindness. If the problems originates from other medical conditions, it can be prevented only if the specific condition that leads to night blindness is preventable.[ic.steadyhealth.com]
