Photoreceptors and Visual Pathways

8.6K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Anatomy of the Eyeball

9.3K
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...

The Retina01:32

The Retina

74.0K
The retina is a layer of nervous tissue at the back of the eye that transduces light into neural signals. This process, called phototransduction, is carried out by rod and cone photoreceptor cells in the back of the retina.

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:

  • 持续扩散光受体失调 (PDPD) 是一种新发现的视网膜疾病.
  • 标志着OCT的圆形区域和指纹间区域的破坏.
  • 与其他外部视网膜病变不同,它呈现出亚急性视力丧失和基本上不显著的 fundus 检查.

研究的目的:

  • 描述持续的扩散光受体失调 (PDPD).
  • 为了建立PDPD的诊断标准.
  • 为了区分PDPD与类似的外视网膜疾病.

主要方法:

  • 在OCT上对14名患者 (21只眼睛) 具有亚急性视力丧失和持续的扩散光受体失调的回顾性观察病例系列.
  • 分析了多模式成像,包括OCT, fundus自光 (FAF),光素血管造影 (FA) 和绿色血管造影 (ICGA).
  • 视觉功能的评估是使用电网光学 (ERG) 和视觉场.

主要成果:

  • 患者在OCT上呈现亚急性视力丧失 (BCVA 0.9 LogMAR平均值) 和扩散光感受器失调,包括缺席的圆形和指节间区域.
  • 在受影响的眼睛中,外视网膜厚度显著降低 (118.3微米对147.6微米).
  • 在75%的眼睛中,FA显示了外周静脉泄漏;ERG显示幅度降低,视野显示显著缺陷.

结论:

  • PDPD是一种独特的实体,其特点是持续的光感受器失调,视觉预后通常不佳.
  • 诊断标准包括亚急性视力丧失,不显著的底部和特定的OCT发现.
  • 需要对PDPD病原和治疗进行进一步的研究.
