概括
本案例研究描述了急性中枢视网膜动脉阻塞 (CRAO),在光素血管学 (FFA) 上呈现异常的墨迹超透泄漏,模仿中枢血清性胆色素病变 (CSCR). 泄漏很可能是由于红细胞聚集.
科学领域:
- 眼科医生 眼科 眼科
- 医疗成像医学成像
- 血管疾病 血管疾病
背景情况:
- 中央视网膜动脉封闭 (CRAO) 是一种导致突然视力丧失的严重疾病.
- 眼底光素血管造影 (FFA) 对于诊断视网膜血管疾病至关重要.
- 区分CRAO与其他疾病,如中央血清性胆色素变异症 (CSCR),对于适当的管理至关重要.
研究的目的:
- 为了记录一种独特的急性CRAO病例,该病例在FFA上表现出油墨斑超光泄漏.
- 分析这种非典型的CRAO表现的成像特征和临床表现.
主要方法:
- 一名21岁的女性在右眼出现了急性无痛视力丧失.
- 临床检查显示了相对的 afferent瞳孔缺陷.
- 进行了 fundus 检查,光学连贯性断层扫描 (OCT) 和 FFA.
主要成果:
- 诊断出急性CRAO,OCT发生严重变化.
- FFA显示了中期的超光泄漏与晚期的持久性,类似于CSCR.
- OCT排除了神经传感器分离,泄漏在第10天得到解决,OCT显示CRAO慢性.
结论:
- 该研究报告了急性CRAO中FFA的墨迹泄漏模式,此前与CSCR相关.
- 假设CRAO中的这种模式是红细胞聚合或rouleaux形成的结果.

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
