Tag: Causes of blindness

According to the World Health Organization (WHO), an estimated 250,000 to 500,000 vitamin A-deficient children become blind every year, with half of them dying within 12 months of losing their sight. The single most frequent and devastating cause of nutritional blindness is vitamin A deficiency, a condition that severely impacts global health, particularly in low-income countries.

According to research, optic neuropathy, a condition leading to vision loss, is a recognized complication of severe vitamin B12 deficiency. While uncommon, this damage to the optic nerve can ultimately cause permanent blindness if left untreated. This article explores how a lack of vitamin B12 impacts eye health, the symptoms to watch for, and the treatment needed to potentially reverse vision damage.
