Full description

Former animal studies had shown that Cordyceps cicadae mycelia can effectively ameliorate UVB-induced dry eye symptoms. This study further investigated its efficacy in human dry eye status by randomized, double-blinded tests, including dry eye questionnaires, blood tests, salivary tests, tear volume test, intra-ocular pressure assessments, ocular surface photography, corneal fluorescein stain, tear film breakup time test, fundus photography, and cornea impression cytology. All tests were performed again after 3 months of dietary supplement of either samples or placebo. A total of 97 participants completed the trial. The data were analyzed by paired-t test and compared between the placebo and the experimental groups.
