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。
This review evaluates the efficacy of non-contact semiconductor laser transscleral ciliary body photocoagulation in the treatment of glaucoma. 16 eyes of 15 patients, 3 neovascular glaucoma, 8 cases of slow closure, 4 cases of chronic open angle and 1 case of secondary glaucoma after trauma. Under the surface anesthesia, 1mm photocoagulation 360 ° after the angle and margin (the photocoagulation point was evenly distributed, the number of points was 25-110, the spot diameter was 200μm, the power was 0.75-1W, the pulse width was 3-5s, the defocus was 1.5mm, the average follow-up time was 3 Month, the average intraocular pressure decreased from 27.1 ± 7.5mmHg to 19.5 ± 8.4mmHg, with an average decrease of 7.6 ± 4.6mmHg.The postoperative IOP decreased with the energy of photocoagulation, and 12 cases (75%) of photocoagulation Upper quadrant mild to moderate pain. Postoperative complications were conjunctival hyperemia in 7 cases (44%), were within 1 week subsided .1 (6%) postoperative pain was significantly, 1 week after remission .Results Show that the surface should be non-contact surface anesthesia DCCP is a simple, easy and effective treatment of glaucoma.
