为评价六项常规临床试验对鉴别早期急性非缺血型和缺血型视网视中央静脉阻塞(CRVO)的作用,对128例140眼进行了前瞻性研究。上述常规临床试验包括视力、视野、相对性瞳孔传人障碍(RAPD)和ERG等四项功能试验,以及眼底镜检查和眼底荧光血管造影等两项形态学试验。发现各项试验均无100%的敏感性和特异性,但六项试验的综合资料却几乎完全可靠。其中,RAPD对鉴别单眼CRVO(对侧眼正常)最可靠,ERG次之,这两项的综合资料可鉴别97%的病例,视野测定次于ERG,视力试验更次,两项形态学试验的鉴别作用最差。
To evaluate the role of six routine clinical trials in identifying early acute non-ischemic and ischemic retinal vein occlusion (CRVO), a prospective study of 128 patients with 140 eyes was performed. The above routine clinical trials include four functional tests such as visual acuity, visual field, relative pupilar disorder (RAPD) and ERG, as well as two morphological tests, ophthalmoscopy and fundus fluorescein angiography. None of the tests found 100% sensitivity and specificity, but the comprehensive data from the six trials were almost completely reliable. Among them, RAPD is the most reliable method to identify monocular CRVO (contralateral eye normal), followed by ERG, the two comprehensive data can be identified in 97% of cases, field of vision secondary to ERG, visual acuity test more times, two morphological tests Identification of the worst.
