概括

外核层 (ONL) 厚度准确地测量了帕奇科罗伊德疾病中的光受体功能. 早期治疗新血管化或排泄对于在这些条件下保持视力至关重要.

科学领域:

眼科医生眼科眼科
视网膜疾病视网膜疾病
光学一致性断层扫描 (OCT)

背景情况:

包皮色素表皮病 (PPE) 和包皮色素新血管病 (PNV) 是影响胸膜和视网膜的疾病.
评估光受体功能对于了解疾病进展和视觉结果至关重要.

研究的目的:

评估外核层 (ONL) 厚度作为PPE和PNV中光受体功能的生物标志物.
为了确定帕奇科罗伊德特征,新血管化和排泄史对光受体功能的影响.

主要方法:

追溯分析了101只具有帕奇科罗伊德特征的眼睛和34只对照眼睛.
通过OCT血管造影,将群体分为PNV和PPE,PNV通过排泄史进一步分层.
测量视网膜和胸膜层厚度和最佳校正视敏度 (BCVA),并进行相关性分析.

主要成果:

在不同组中,ONL厚度显著不同,与BCVA线性相关.
PNV眼睛有最薄的ONL,其次是PPE,然后是对照.
在PNV眼睛的脱落与更薄的ONL和更糟糕的BCVA有关.

结论:

在PNV和PPE中,ONL厚度是光受体功能的可靠的定量生物标志物.
光受体功能受到帕奇科罗伊德特征,新血管化和排泄的损害.
迅速治疗新血管化或排泄是防止光受体损失至关重要的.

Anatomy of the Eyeball

Anatomy of the Eyeball

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...
