We used titanium retinal tacks inserted with a pneumatic instrument for retinal fixation in 11 operative procedures in ten eyes with complicated retinal detachments. Titanium was selected for permanent implantation because of its documented biologic tolerance. No intraoperative or postoperative complications related to the tacks were encountered. Three tacks, one 0.7 mm in length and two 1.6 mm in length, became dislodged postoperatively; 50 permanently implanted tacks, each 1.6 mm in length, remained in place after a mean follow-up of five months. Retinal reattachment at the end of the follow-up period was achieved in eight eyes and useful visual function was obtained in three eyes. Titanium retinal tacks are useful when immediate retinal fixation is required either temporarily or permanently to prevent retraction and detachment of the retina until adjunctive diathermy, cryopexy, or photocoagulation becomes effective.
我们使用气动器械插入钛制视网膜钉，对10只患有复杂性视网膜脱离的眼睛进行了11次手术操作，以固定视网膜。选择钛用于永久植入是因为其已被证实的生物耐受性。未遇到与视网膜钉相关的术中或术后并发症。术后有3枚视网膜钉移位，其中1枚长0.7毫米，2枚长1.6毫米；平均随访5个月后，50枚永久植入的、每枚长1.6毫米的视网膜钉仍留在原位。随访期末，8只眼睛实现了视网膜复位，3只眼睛获得了有用的视觉功能。当需要临时或永久立即固定视网膜以防止视网膜回缩和脱离，直到辅助透热疗法、冷冻疗法或光凝疗法起效时，钛制视网膜钉是有用的。
