概括
使用抗血管内皮生长因子 (VEGF) 治疗的与年龄相关的黄斑变性 (AMD) 眼睛的视力敏度 (VA) 与视网膜厚度没有直接联系. 然而,在考虑视网膜厚度偏差时发现了显著的关联,这表明其在结构功能相关性中的实用性.
科学领域:
- 眼科医生 眼科 眼科
- 视网膜疾病 视网膜疾病
- 医疗成像医学成像
背景情况:
- 与年龄相关的黄斑变性 (AMD) 是导致视力丧失的主要原因.
- 抗血管内皮生长因子 (抗VEGF) 治疗是新血管AMD的主要治疗方法.
- 了解视网膜结构和视觉功能之间的关系对于治疗监测至关重要.
研究的目的:
- 调查视觉敏度 (VA) 和视网膜厚度与接受抗VEGF治疗的新血管AMD之间的联系.
- 探索VA与绝对视网膜厚度和视网膜厚度偏差之间的相关性.
主要方法:
- 对68名新血管性AMD患者的回顾性分析,这些患者接受了抗VEGF治疗.
- 两年后续成像数据,包括基于OCT的参数.
- 线性和非线性回归分析以评估VA和视网膜厚度/偏差在3个月和24个月之间的关系.
主要成果:
- 在VA和3个月或24个月的foveal或parafoveal视网膜厚度之间没有发现显著的线性关联.
- 在24个月后,观察到VA和叶视网膜厚度偏差之间存在弱但具有统计学意义的线性关联.
- 在VA和3个月和24个月的偏视网膜厚度偏差之间也发现了显著的线性关联.
结论:
- 仅仅视网膜厚度本身并不是治疗新血管AMD的视力敏度的强有力的预测指标.
- 然而,视网膜厚度偏差与视力敏度有显著的相关性.
- 基于偏差的参数可以为在AMD中监测抗VEGF治疗提供更好的结构功能相关性.

Glaucoma: 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...
Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Diabetic Retinopathy
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...
