概括
青光眼的进展因阶段而异. 圆柱状视网膜神经纤维层 (cpRNFL) 稀薄预测早期绿眼的视野 (VF) 损失,而黄斑结节细胞内状层 (mGCIPL) 稀薄在后期更为关键.
科学领域:
- 眼科医生 眼科 眼科
- 神经科学是一个神经科学.
- 医疗成像医学成像
背景情况:
- 玻璃眼是导致不可逆转失明的主要原因.
- 早期检测和监测青光眼的进展对于保持视力至关重要.
- 对视网膜的结构变化进行量化,例如环皮状视网膜神经纤维层 (cpRNFL) 和黄斑结节细胞内状层 (mGCIPL),是了解疾病进展的关键.
研究的目的:
- 为了比较cpRNFL和mGCIPL在有视野 (VF) 进展和没有视野 (VF) 进展的青光眼患者中的稀释率.
- 为了分析这些在不同阶段的青光眼严重程度的稀释率.

主要方法:
- 这是一项追溯的纵向研究,涉及1,605名患者的2,464只眼睛,至少有5次可靠的cpRNFL,mGCIPL和VF测量.
- 使用线性回归计算了根据青光眼的严重程度 (可疑,轻度,中度,晚期) 分层的稀释率 (μm/年).
- 后勤混合效应模型评估了稀释率对VF进展概率的影响.
主要成果:
- 与没有进展的眼睛相比,VF进展的眼睛显示出明显更快的cpRNFL和mGCIPL稀释 (-1.02和-1.04微米/年) (-0.41和-0.41微米/年).
- 随着疾病严重程度的增加,进展者和非进展者之间的瘦身率差异下降.
- cpRNFL的稀释与早期玻璃眼炎的VF进展更强烈相关,而mGCIPL的稀释在后期阶段显示出更强烈的关联.

Glaucoma: Overview
755
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...

Anatomy of the Eyeball
7.6K
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...

Open Angle Glaucoma: Treatment
568
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.
