为了确定激光光凝在视网膜和色素上皮之间产生结合的速度有多快，作者测量了激光灼烧完整和最近重新附着的兔视网膜后视网膜粘附的强度。完整视网膜光凝后，粘合力在8小时内下降50%，但在24小时内增加，超过正常水平（约140%），在3天至4周内保持正常水平的两倍。对实验脱离后刚刚沉淀的视网膜进行光凝处理，结果类似，但最大粘连强度（2周时达到）是正常的3倍。相比之下，自发再附着的视网膜，在没有光凝的情况下，24小时的粘连性仅为正常的10%，4周后仍仅为正常的75%。这些数据表明，激光光凝可能是非常有益的预防或管理视网膜撕裂和脱离。
To determine how quickly laser photocoagulation produces a bond between retina and pigment epithelium, the authors measured the strength of retinal adhesion after making laser burns through intact and recently reattached rabbit retina. After photocoagulation of intact retina, the adhesive force was reduced 50% at 8 hours but increased beyond normal (to approximately 140%) by 24 hours and remained twice normal between 3 days and 4 weeks. Photocoagulation of retina that had just settled after experimental detachment produced similar results, except that the maximum strength of adhesion (reached at 2 weeks) was three times normal. In contrast, retina that reattached spontaneously, without photocoagulation, showed only 10% of normal adhesiveness at 24 hours, and still was only 75% of normal after 4 weeks. These data suggest that laser Photocoagulation may be acutely beneficial in the prevention or management of retinal tears and detachments.
