To treat patients with traction detachment of the central retina by laser in order to avoid vitrectomy.
Focal treatment of and around the flat detached retinal area with the argon laser.
Seven patients were treated for macular-threatening traction detachment of the retina. The non-rhegmatogenous traction detachment was flat and circumscribed. Panretinal photocoagulation (PRP) with the argon laser was performed prior to treatment of the traction in three of the cases, in four it was carried out in addition to PRP. In each of the seven patients partial or complete reattachment and stabilization for many years was achieved, rendering vitrectomy unnecessary (mean follow-up after therapy: 40.1 months). In no case was a laser-induced hole produced, and in no patient did the visual acuity decrease.
The favourable results following photocoagulation can be explained by the tight retinal/choroidal scar formation (laserpexy). Laserpexy is only recommended for eyes with slight initial detachment.
通过激光治疗中心视网膜牵引性脱离患者，以避免玻璃体切除术。
用氩激光对扁平脱离的视网膜区域及其周围进行局部治疗。
7例患者因黄斑受累的视网膜牵引性脱离接受治疗。非孔源性牵引性脱离扁平且边界清晰。7例中有3例在治疗牵引之前先行氩激光全视网膜光凝（PRP），4例在PRP基础上再加用该治疗。7例患者均实现了部分或完全复位，并稳定多年，无需进行玻璃体切除术（治疗后平均随访40.1个月）。无一例产生激光诱导孔，且无一例患者视力下降。
光凝术后的良好效果可通过紧密的视网膜/脉络膜瘢痕形成（激光固定术）来解释。激光固定术仅推荐用于初始脱离较轻的眼睛。
