The retinal tack is a useful adjunctive instrument in the repair of complicated retinal detachments. To examine the tissue response of chronically implanted alloy tacks, we implanted a series of tacks into rabbit eyes. Their effects were observed at 1 and 4 weeks, at 6 months, and at 2.5 years after insertion. Our observations indicate that the histology and electrophysiology of the retina was generally not affected. All tacks were surrounded by connective and/or glial tissue scar and induced firm retinal adherence. The retinal architecture was normal within 1 mm of the scar, indicating that these alloy tacks do not cause tissue damage outside the immediate area of the wound, even when left in place over a period of 2 years.
视网膜钉是修复复杂性视网膜脱离的一种有用辅助器械。为了研究长期植入的合金钉的组织反应，我们将一系列钉植入兔眼。在植入后1周、4周、6个月和2.5年观察其效果。我们的观察表明，视网膜的组织学和电生理学一般不受影响。所有的钉都被结缔组织和/或神经胶质组织瘢痕包围，并引起视网膜牢固附着。瘢痕周围1毫米内的视网膜结构正常，这表明即使这些合金钉在原位放置2年，也不会在伤口直接区域之外造成组织损伤。
