目的探讨氩激光视网膜光凝联合曲安奈德球内注射治疗缺血型视网膜中央静脉阻塞(CRVO)的临床疗效。方法2003年12月至2005年1月对17例(17只眼)缺血型CRVO患者行氩激光视网膜光凝联合曲安奈德球内注射治疗。结果随访4～10个月。16例患者视力提高,其中14例患者黄斑水肿明显减轻或消失,5例患者在3个月以后黄斑水肿复发,视力下降。6例患者在球内注射后出现眼压升高,给予对症处理后缓解。无房角新生血管形成及继发性新生血管性青光眼发生。结论氩激光视网膜光凝联合曲安奈德球内注射治疗缺血型CRVO可以提高患者视力,减少并发症。但是一部分患者黄斑水肿可能复发。
Objective To investigate the clinical effect of argon laser retinal photocoagulation combined with triamcinolone acetonide intracranial injection on ischemic central retinal vein occlusion (CRVO). Methods From December 2003 to January 2005, 17 patients (17 eyes) with ischemic CRVO underwent argon laser retinal photocoagulation combined with intravitreous injection of triamcinolone acetonide. The results were followed up for 4 to 10 months. Visual acuity improved in 16 patients, of which 14 patients with macular edema significantly reduced or disappeared, 5 patients with macular edema recurrence after 3 months, vision loss. Six patients with intraocular pressure after intraocular pressure, given symptomatic relief after treatment. No angiogenesis and secondary neovascular glaucoma. Conclusion Argon laser photocoagulation combined with intravitreous injection of triamcinolone acetonide for the treatment of ischemic CRVO can improve visual acuity and reduce complications in patients. However, some patients with macular edema may relapse.
