摘要
本文评价了非接触性半导体激光透巩膜睫状体光凝治疗青光的疗效。15名患者16只眼,新生血管性青光眼3例,慢闭8例,慢性开角型4例,外伤后继发性青光眼1例。表面麻醉下于角巩缘后1mm光凝360°(,均匀分布光凝点,点数25—110,光斑直径200μm,功率0.75-1W,脉宽3-5s,离焦1.5mm。平均随访时间3月,平均眼压从术前27.1±7.5mmHg下降至19.5±8.4mmHg,平均下降7.6±4.6mmHg。术后眼压下降值与光凝况能量相关,术中12例(75%)光凝颞上象限时有轻至中度疼痛。术后并发症有结膜充血7例(44%),均于1周内消退。1例(6%)术后天疼痛明显,1周后缓解。以上结果表明应表表面麻醉非接触式DCCP是一种简便、易行,有一定疗效的治疗青光眼的方法。
The study evaluated the clinical efficacy of non contact diode laser transscleral cyclophotocoagulation for the treatment of glaucoma.Sixteen eyes of 15 patients with medically and surgically uncontrollable glaucoma enrolled in this study.There were 3 neovascular glaucoma,8 closed angle glaucoma,4 open angle glaucoma,1 traumatic glaucoma.Under topical anesthesia,laser spots(25 110)were evenly placed 360(around the limbus.The laser was focused initially on the sclera 1mm from the surgical corneal scleral limbus,then defocused 1.5mm posteriorly.The laser was operated with a power of 0.75 1W,duration of 3 5S,and the spot size was 200μm.Three months after surgery,the mean preoperative IOP of 27.1(7.5mmHg had dropped to 19.5(8.4mmHg.Postoperative IOP reduction was related to total energy used.Complications included conjunctival hyperemia in 7 eyes(44%).One eye had severe pain 1 day postoperation.All complications relieved within one week.These results indicated that non contact diode laser transscleral cyclophotocoagulation with topical anesthesia is a simple,safe and effective procedure.
