Prevention and Treatment of Cataracts with Reference to Chinese Medicine

It is estimated (by Pro Ro Nata, Inc., a consulting firm) that traditional Chinese medicine products for eye disorders accounted for 41 million dollars (U.S.) of business in 2002, with 80% sold over the counter in pharmacies, the rest prescribed at hospitals and clinics. Cataracts are a major target of therapy, with 40% of the ophthalmic drug market (including non-TCM therapies). Unfortunately, little is known about the success rate for these treatments. Both internal and topical therapies are used.
