AIM： To evaluate the efficacy of goji berry supplementation on improving macular pigment, serum zeaxanthin levels and visual acuity in patients with early age-related macular degeneration （AMD）. METHODS： A total of 114 patients （aged from 51 to 92y, mean age 69.53±8.41y） with early AMD were enrolled in our prospective, randomized controlled study. The included patients were assigned randomly to the goji group （n=57） with 25 g of goji berries supplementation per day for 90d and the control group （n=57） with their normal diet for 90d. Macular pigment optical density （MPOD） was measured using heterochromatic flicker photometry （HFP）. The levels of serum lutein （L）/zeaxanthin （Z） were analyzed using high-performance liquid chromatography （HPLC）. MPOD, serum L/Z levels and best corrected visual acuity （BCVA） were recorded at baseline and 90d. RESULTS： In the goji group, there were no statistically significant differences in the serum L levels between the baseline （0.199±0.149 μmol/mL） and 90d （0.203±0.181 μmol/mL）（t=-0.186, P=0.850）; however the serum Z levels were increased at 90d （0.101±0.087 μmol/mL） compared with those at the baseline （0.029±0.032 μmol/mL）（t=6.412, P〈0.001）. Patients treated with goji berry for 90d showed an elevated MPOD （0.877±0.202 DU） from the baseline （0.731±0.205 DU）（t=-4.741, P=0.000）. In contrast to the control group, the serum Z levels and MPOD were higher in the goji group at 90d （both P〈0.05）. At 90d, patients with goji berry supplementation had a relative decrease in BCVA （0.21±0.18 logMAR） compared with the baseline （0.27±0.20）（t=2.397, P=0.020）. CONCLUSION： Overall, daily supplementation with goji berry for 90d improves MPOD by increasing serum Z levels rather than serum L levels in early AMD patients. goji berry may be an effective therapeutic intervention for preventing the progression of early AMD.
