Http://www.44dx.com objectiveto investigate the therapeutic effects of subconjunctival verapamil on outcome in an experimental model of traumatic proliferative vitreoretinopathy.methodsan experimental model of traumatic proliferative vitreoretinopathy was induced in pigment rabbits,which then were selected randomly to receive either subconjunctival verapamil injection treatment or a placebo injectiondaily for 3 weeks.animals were examined by indirect ophthalmoscopy at weekly intervals for 5 weeks.eyes were enucleated for light microscopy 5 weeks later.resultsfifty-six percent(18 of 32)of the rabbits receiving subconjunctival verapamil injection had developed tractional retinal detachment,whereas eighty-one percent(26 of 32)of control animals had developed tractional retinal detachment(χ2=4.655,p=0.031).the results of clinical examination and light microscopy didn?

http：//www.44dx.com 目的观察维拉帕米(verapamil，ver)对眼后节穿通伤增生性玻璃体视网膜病变(proliferative vitreoretinopathy，pvr)的影响。方法64只青紫蓝兔，每只兔任选其中一只眼制备外伤性pvr模型后随机分为两组，治疗组在模型制备后立即每日结膜下注射2.5 mg/ml的ver0.5ml，对照组则每日结膜下注射生理盐水0.5ml，共21天。模型制备后7天内每天用裂隙灯显微镜及间接立体检眼镜观察伤口、角膜、前房及眼底情况，此后每周第3，7天各检查1次。伤后第35天时常规摘除模型制备眼作光镜观察。
