In order to evaluate the tissue response to metal retinal tacks experiments were carried out on 4 monkey eyes and compared to those on 4 rabbits. Non-magnetic retinal tacks (Grieshaber, Switzerland) and tacks made of 24 carat gold (our own brand) were inserted into the ocular fundus under microscopic control. The animals were kept for 3 months. In monkey eyes, histological examination disclosed a considerable fibrovascular proliferation around the retinal tack canal, including an inflammatory response, formation of collagenous tissue and glial proliferation. There was a local intra-retinal and epi-retinal neovascularization. In the rabbit retina, only a slight inflammation and thin collagenous tissue developed. Thus the tissue response was much more severe in the primate eye than in the avascular rabbit retina.
为了评估组织对金属视网膜钉的反应，对4只猴眼进行了实验，并与4只兔眼的实验结果进行比较。在显微镜控制下，将非磁性视网膜钉（瑞士格里沙贝尔公司生产）和24K金制成的视网膜钉（我们自己的品牌）植入眼底。动物饲养3个月。在猴眼中，组织学检查显示视网膜钉通道周围有大量纤维血管增生，包括炎症反应、胶原组织形成和神经胶质增生。存在局部视网膜内和视网膜上新生血管形成。在兔视网膜中，仅出现轻微炎症和薄的胶原组织。因此，灵长类动物眼的组织反应比无血管的兔视网膜严重得多。
