Effects of Vitamin C and Lycium Barbarum Supplements on the Progression of Senile Cataract in Hong Kong Chinese Population

2014-08-27 03:12:56 | BioPortfolio

Summary

With the rapid growing aging population, age-related eye diseases including cataract are becoming more prevalent. The demand for cataract surgery and post-surgical care posed enormous financial burdens to the government.

Vitamin C, also known as ascorbate, is a highly effective antioxidant which may help to protect the cells including the crystalline lens components from oxidative damage, which is believed to be one of the causes of senile cataract.

Lycium barbarum, on the other hand, contains lutein and zeaxanthin which can filter the phototoxic blue light and neutralize the reactive oxygen species, thus provide a protective effect against cataract formation.

This study aims to determine the effects of Vitamin C and Lycium barbarum Supplements on the progression of senile cataract in Hong Kong Chinese elderly.

Medical and Biotech [MESH] Definitions

Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. The many kinds of cataract are classified by their morphology (size, shape, location) or etiology (cause and time of occurrence). (Dorland, 27th ed)

A lipid cofactor that is required for normal blood clotting. Several forms of vitamin K have been identified: VITAMIN K 1 (phytomenadione) derived from plants, VITAMIN K 2 (menaquinone) from bacteria, and synthetic naphthoquinone provitamins, VITAMIN K 3 (menadione). Vitamin K 3 provitamins, after being alkylated in vivo, exhibit the antifibrinolytic activity of vitamin K. Green leafy vegetables, liver, cheese, butter, and egg yolk are good sources of vitamin K.

A nutritional condition produced by a deficiency of VITAMIN D in the diet, insufficient production of vitamin D in the skin, inadequate absorption of vitamin D from the diet, or abnormal conversion of vitamin D to its bioactive metabolites. It is manifested clinically as RICKETS in children and OSTEOMALACIA in adults. (From Cecil Textbook of Medicine, 19th ed, p1406)
