The treatment of peripheral retinal tears by laser photocoagulation is an accepted technique. One of its limitations is its difficulty in use near the ora serrata. The inability to treat the anterior border of a rentinal tear may allow the tear to progress to clinical retinal detachment despite treatment of the tear's posterior and lateral borders. The use of a scleral indentation funnel at the time of laser photocoagulation permits the sealing of all margins of the break. This technique increases the number of retinal tears that can be treated by the laser, and it may improve the rate of success of photocoagulation of peripheral retinal tears.
通过激光光凝治疗周边视网膜裂孔是一种公认的技术。其局限性之一是在锯齿缘附近使用困难。尽管对视网膜裂孔的后部和侧部边界进行了治疗,但无法治疗裂孔的前缘可能会使裂孔发展为临床视网膜脱离。在激光光凝时使用巩膜压陷漏斗可封闭裂孔的所有边缘。该技术增加了可通过激光治疗的视网膜裂孔数量,并且可能提高周边视网膜裂孔光凝的成功率。
