Why oral administration of vitamin B12 not effective as a treatment of pernicious anemia?
Pernicious anemia is due to a deficiency of a vitamin called intrinsic factor, which is normally produced by cells of the stomach. Intrinsic factor is required for the absorption of vitamin B12, so if intrinsic factor levels are insufficient, vitamin B12 will not be absorbed well. So administration of vitamin B12 will only help treat vitamin B12-deficiency anemia if vitamin B12 can be absorbed, and this can only happen if there are adequate levels of intrinsic factor to begin with. Patients with pernicious anemia do not have adequate intrinsic factor levels, so they will not be helped by vitamin B12 treatment since they can't absorb it well enough.

What kind of vitamin you get in eye?
Vitamin A helps protect the surface of the eye (cornea), it is essential for good vision. Studies show vitamin A eye drops are effective for the treatment of dry eyes. In fact, one study found that over-the-counter lubricating eye drops containing vitamin A were as effective for the treatment of dry eye syndrome as more expensive prescription eye drops formulated for dry eye relief. Vitamin A eye drops also have been shown effective for the treatment of a specific type of eye inflammation called superior limbic keratoconjunctivitis. Vitamin A, at least when in combination with other antioxidant vitamins, also appears to play a role in decreasing the risk of macular degeneration (AMD). In the landmark Age-Related Eye Disease Study (AREDS) sponsored by the National Eye Institute, people at high risk for the disease who took a daily multiple vitamin that included vitamin A (as beta carotene), vitamin C, vitamin E, zinc and copper had a 25 percent reduced risk of advanced AMD during a six-year period. It also appears that a combination of vitamin A and lutein may prolong vision in people suffering from retinitis pigmentosa (RP). A recent four-year study conducted by researchers from Harvard Medical School and other prominent universities found that individuals with retinitis pigmentosa who took daily supplements of vitamin A (15,000 IU) and lutein (12 mg) had a slower loss of peripheral vision than those who did not take the combined supplements. Because beta carotene is converted into vitamin A in the body, it's likely beta carotene (provitamin A) offers similar eye benefits as the pre-formed retinol type of vitamin A, though more research is needed to confirm this.
