Effect of a Dietary Supplement of Carp Gallbladder Powders on Visual Functions in Elder Ophthalmic Patients

Abstract

Effects of a dietary supplement of carp gallbladder powders, New-Eyereturn^®, on visual functions were investigated in elder ophthalmic patients. The tablets (12 tablets/day) were taken by 15 and 12 subjects for one-month and three-month period, respectively. In comparison with the visual function data at baseline and thereafter, improvements of subjective symptoms by questionnaire was observed in a three-month intake group, although no significant difference of the values of visual acuity and intraocular pressure was recognized. These results suggest intake of this dietary supplement has a possibility to improve visual functions of elder people.
