用２５４．７５ｃｄ的荧光灯作为光源，照射大鼠视网膜，建立光损伤动物模型。对照组大鼠视网膜光镜下见锥体、杆体细胞层破坏严重，外核层紊乱，细胞核数目明显减少。电镜下，外节破坏溶解、空泡形成，内节肿胀，视网膜色素上皮（ＲＰＥ）坏死；口服枸杞的治疗组则表现为锥体、杆体层轻度破坏，外核层排列较整齐，细胞数目接近正常。表明枸杞对大鼠视网膜锥体、杆体层、外核层和ＲＰＥ有明显的保护作用。
A 254.75cd fluorescent lamp was used as a light source to irradiate the rat retina to establish an animal model of photodamage. In the control group, under the light microscope of the retina, the pyramidal and rod cell layers were severely damaged, the outer nuclear layer was disordered, and the number of nuclei was significantly reduced. Under the electron microscope, the external joints destroyed the dissolution and vacuolization, the internal joints were swollen, and the retinal pigment epithelium (RPE) necrosis. In the oral sputum treatment group, the cones and rods were slightly damaged, and the outer nuclear layer was arranged neatly. Near normal. It was shown that wolfberry has obvious protective effects on rat retina cone, rod body layer, outer nuclear layer and RPE.
