概括
在黄斑疾病中,自然的偏好视网膜位置 (PRL) 通常在上视网膜中形成,以保持视力. 一些患有黄斑疾病的眼睛不会发展成PRL,尤其是广泛的病变.
科学领域:
- 眼科医生 眼科 眼科
- 视网膜成像 视网膜成像
- 视觉神经科学 视觉神经科学
背景情况:
- 黄斑疾病 (MD) 可以显著影响视觉功能.
- 首选视网膜位置 (PRL) 对于维持中部视力丧失的个体的视力敏度至关重要.
- 了解MD中的自然PRL特征对于视觉康复至关重要.
研究的目的:
- 研究各种黄斑病变的眼睛中的自然PRL的特征和分布.
- 在不同的PRL位置比较固定稳定性和视觉功能的指标.
- 确定影响PRL发展和在黄斑疾病中局部化的因素.
主要方法:
- 对37名患有黄斑疾病的患者 (39只眼睛) 的回顾性分析.
- 收集最佳校正的视力敏度 (BCVA),黄斑敏感度 (MS) 和双变的轮圆周面积 (BCEA).
- 评估固定稳定性和膜的底部/截面成像.
主要成果:
- 在39只眼睛中,有10只眼睛没有出现自然的PRL.
- 自然PRL在29只眼睛中发展,其中42%的眼睛是上层眼睛,24%的眼睛是鼻腔眼睛,17%的眼睛是眼睛,7%的眼睛是多眼睛.
- 在"黑暗区域"内的PRL显示出明显较低的平均灵敏度;与上部,部和鼻腔组相比,黄斑病变组的BCEA变化更大.
结论:
- 黄斑疾病中的自然PRL倾向于优越地局部化,可能会保留较低的视野.
- PRL的发展受到病变特征的影响,广泛的病变可能会形成多个PRL.
- 完整的叶功能可以防止PRL的形成,即使有斑点病变,患者继续使用叶进行固定.

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...

6.5K
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,...

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
