If I have poor night vision, does that mean that my eye health is pretty bad?

Get checked out: Although reversible loss of night vision may be associated with vitamin a deficiency, this is not likely in developed countries with normal diet. How long have you had poor night vision? Do you have congenital hearing loss? Loss of night vision may more likely be secondary to a variety of retinal dystrophies, including, most notably, retinitis pigmentosa (rp). When associated with congenital hearing loss, rp is part of usher’s syndrome. Symptoms are progressive nyctalopia (night vision loss) and constriction of visual fields (ie: inability to see immediate surroundings like stair rails or peripheral traffic when gazing forward). Other conditions may cause similar symptoms but are less common. Diagnosis is made by ophthalmologic examination including ophthalmoscopy, erg and visual field testing. Cataracts may occur and further impair vision. Unfortunately, there is presently no recommended therapy to arrest or cure these conditions but research is being conducted into the effects of neuroprotective agents as well as surgical remedies with stem cell and retinal pigment epithelial replacement. Please have your eyes dilated and examined. ...Read more
