- Asymptomatic
Nine years later she presented with night blindness, severe diarrhea and mild jaundice and was found to have malabsorption with vitamin A and K deficiencies as well as asymptomatic liver cirrhosis. [ncbi.nlm.nih.gov]
She was asymptomatic in daylight, but almost blind in the dark to the extent where she found driving difficult unless weather conditions were clear and bright. [journalofoptometry.org]
If an asymptomatic hydrocele obscures physical examination of the testicle, this study may be appropriate prior to surgical intervention. [emedicine.medscape.com]
- Weakness
It is helpful in dealing with weakness of Optic Nerves. Collect black Basil leaves and grind them to extract its juice. Use this juice as an eye drop. Put one drop in the affected eye daily before going to bed. [herbpathy.com]
This medical conditions primarily affects the brain and motor functions and apart from night blindness there are many different symptoms such as deafness, weakness, balance and coordination problems. [ic.steadyhealth.com]
The patient, in the initial phase of retinitis pigmentosa, perceives compromised minor and weak light vision due to the decline of the rod photoreceptors. Later, this will be followed by irregularities in the adjacent retinal pigment epithelium. [manipalhospitals.com]
Night Blindness is also seen to occur in people with pancreatic disorders as weak pancreas fail to absorb adequate vitamin A and he body gets vitamin A deficiency resulting in Night Blindness. [epainassist.com]

- Pallor
The retina usually appears normal, although the optic nerve may show myopic tilt and temporal pallor. An ERG must be performed for diagnosis. [aao.org]
Retinal thinning, bone spicule pigmentation, vascular attenuation, optic disc pallor, and pigmentary atrophy have all been noted. [disorders.eyes.arizona.edu]
- Surgical Procedure
This expensive surgical procedure may do more harm than good. Choose the safest option for improving your vision. [rebuildyourvision.com]
Gastrointestinal
- Overeating
Usually, individuals over the age of 50 develop this issue. A person’s vision gets deteriorated over a period of time, eventually resulting into night blindness. [healthguidance.org]
However, it took over 1 year for his vitamin A level to return to normal. [ncbi.nlm.nih.gov]
Liver, Gall & Pancreas
- Jaundice
Nine years later she presented with night blindness, severe diarrhea and mild jaundice and was found to have malabsorption with vitamin A and K deficiencies as well as asymptomatic liver cirrhosis. [ncbi.nlm.nih.gov]
Skin
- Photosensitivity
Vitamin A deficiency, which causes reduced photosensitivity of rhodopsin (a chromoprotein) in rod cells, causes night blindness that is usually not severe, and vision most often recovers when adequate levels of the vitamin are administered. [britannica.com]
Rhodopsin, maintains its photosensitivity only in the presence of vitamin A. Night blindness is a classic finding from deficiency of vitamin A. [medicinenet.com]
Eyes
- Night Blindness
Acquired Causes Most of the acquired causes of night blindness (night blindness which is not present since birth and does not have a genetic basis), generally fall into the category of progressive night blindness. [web.archive.org]
ERG might be more sensitive than serum vitamin A level and is recommended in case of night blindness but still normal vitamin A level. [ncbi.nlm.nih.gov]
Night blindness is poor vision at night or in dim light. Night blindness may cause problems with driving at night. People with night blindness often have trouble seeing stars on a clear night or walking through a dark room, such as a movie theater. [nlm.nih.gov]
- Strabismus
[…] group of retinal disorders characterized by night or dim light vision disturbance or delayed dark adaptation, poor visual acuity (ranging from 20/30 to 20/200), myopia (ranging from low (-0.25 diopters [D] to -4.75 D) to high (≥-10.00 D)), nystagmus, strabismus [orpha.net]
Nystagmus and strabismus are inconsistent findings. Retinal pigmentation is usually normal in the X-linked forms. Visual acuity ranges from 20/30 to 20/200. [disorders.eyes.arizona.edu]
Congenital stationary night blindness (CSNB) is usually diagnosed based on the owner's observations, but some horses have visibly abnormal eyes: poorly aligned eyes (dorsomedial strabismus) or involuntary eye movement (nystagmus). [en.wikipedia.org]
X-linked congenital stationary night blindness is also associated with myopia, nystagmus, and strabismus (a deviation of the eye, otherwise known as squint or cockeye ). [web.archive.org]

- Photophobia
Nystagmus and photophobia are usually not features. Dyschromatopsia and loss of central acuity can develop later as the cones eventually become dysfunctional as well but these symptoms are much less severe than those seen in cone-rod dystrophies. [disorders.eyes.arizona.edu]

Treatment Treatment Options: No treatment has been reported. [disorders.eyes.arizona.edu]
Prognosis
Prognosis Prognosis is good but depends on the stage of disease with 5- year survival rates as high as 99% in stage 1 disease. [orpha.net]
Prognosis Seminoma of the testis is associated with a good prognosis, with most tumours following an indolent course. In cases without evidence of lymphatic spread, 5 year survival approaches 100%. [healthengine.com.au]
Moreover, data suggest an improved overall prognosis for MBD. [emedicine.medscape.com]

Etiology
However, the etiology of this unique form of unilateral night blindness remains obscure. [ncbi.nlm.nih.gov]
Etiology Etiology is unknown but tumors are thought to arise from an embryonic germ cell leading to testicular intraepithelial neoplasia (the precursor to classical seminoma). [orpha.net]
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 and Pathophysiology It has long been accepted that the etiology of Marchiafava-Bignami disease (MBD) is likely either toxic or nutritional, as it is seen predominantly in malnourished alcoholics. [emedicine.medscape.com]

Prevention
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]
Night Blindness Prevention “Prevention is better than cure”, isn’t it? In most cases, night blindness can be prevented by taking proper care of one’s health. [healthguidance.org]
Prevention and Management By treating the above conditions early it is possible to prevent night blindness. Vitamin A supplementation as a preventative measure will only be effective for night blindness due to vitamin A deficiency. [healthhype.com]
This is the first and foremost reason behind night blindness and is the leading cause of preventable childhood blindness. It is critical to reduce the rate of child mortality. [manipalhospitals.com]
