Retinitis pigmentosa(RP)is a group of heredofamilial retinal diseases which is characterized by night blindness and progressive visual field *** study aims to study the treatment effect of Lycium barbarum(LB)on retinal functions and structure of RP *** study is a double-masked randomized controlled *** subjects received scheduled eye examination including visual acuity(VA),Humphrey field analysis(HFA),ganzfeld flash electroretinogram(ffERG)and optical coherence tomography(OCT).The suitable subjects were randomly allocated to either LB-treatment or placebo groups with the supply of LB or placebo for 12 *** were total 41 RP subjects(22 in LB group and 19 in placebo group)completed the 12 months *** compliance rates for LB and placebo groups were 89.8%±12.5%and 85.3%±7.7%*** compared with placebo group,there were no deteriorations of both high and low contrast VA in LB group(P<0.01).In addition,certain improvements of scotopic rod response and photopic cone response of ffERG were obtained in LB group(P<0.05).In the OCT measurement,an obvious thinning of macular thickness was observed in placebo group but not found in LB group(P<0.05).However,there were no changes found in the sensitivity of central visual field between two *** results confirm that the 12-month LB treatment for RP patients had neuroprotective effect on retina and is believed to delay or minimize the deterioration of visual function in RP.
