对继发于急性视网膜中央动脉阻塞(CRAO)后眼内新生血管形成的发生率进行了前瞻性研究。共研究33例,全部病人在确诊后1周内行静脉荧光造影(IVFA)以排除眼动脉阻塞。全部病人在失明后48小时内入院治疗,包括前房穿刺引流后立即进行眼部按摩,如果无禁忌,则48小时内每2小时给予10分钟的经鼻插管吸人卡波金(carbogen,95%的氧和5%二氧化碳),另外每天二次局部给予0.5%的噻吗心安和口服500mg醋氮酰胺。颈动脉检查
The incidence of ocular neovascularization secondary to acute central retinal artery occlusion (CRAO) was prospectively investigated. A total of 33 cases were studied, all patients within 1 week after diagnosis of intravenous fluorescein (IVFA) to rule out occlusion of the ophthalmic artery. All patients were admitted to hospital within 48 hours after blindness, including an immediate ocular massage immediately after puncture and drainage of the anterior chamber. If no contraindication was given, nasal intubation was given for 10 minutes every 48 hours for 48 hours, 95% oxygen and 5% carbon dioxide) were administered topically and additionally 0.5% timolol and 500 mg acetazolamide were topically administered twice daily.
