At an early clinical stage, patients with cystoid macular oedema show no significant changes in their vision. This phase is described as angiographic cystoid macular oedema. Echographic macular studies have in the past years shown that the macular thickness is increased in the early stages of cystoid macular oedema. In these patients there was no evidence of cystoid macular oedema with the visual acuity test, B-scan echography and fluorescein angiography. In this paper an echographic macular study by standardized A-scan echography was performed in 537 patients before extracapsular cataract extraction and intraocular lens implantation in posterior chamber (ciliary sulcus). The results showed that this method is very sensitive in detecting patients with high risk of cystoid macular oedema.
在临床早期阶段，黄斑囊样水肿患者的视力无明显变化。此阶段被描述为血管造影性黄斑囊样水肿。过去几年的超声黄斑研究表明，在黄斑囊样水肿的早期阶段黄斑厚度增加。这些患者通过视力测试、B超扫描和荧光素血管造影均未发现黄斑囊样水肿的迹象。本文对537例拟行白内障囊外摘除及后房型人工晶状体（睫状沟）植入术的患者，采用标准化A超扫描进行了超声黄斑研究。结果表明，该方法在检测黄斑囊样水肿高危患者方面非常敏感。
