Anatomy of the Eyeball01:20

Anatomy of the Eyeball

6.0K
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...

科学领域:

  • 眼科医生 眼科 眼科
  • 医疗成像医学成像
  • 视网膜疾病 视网膜疾病

背景情况:

  • 近视力拉力巨眼病 (MTM) 涉及高度近视眼睛的复杂视网膜变化.
  • 了解MTM中视网膜形态和视觉功能之间的关系对于患者管理至关重要.

研究的目的:

  • 量化视网膜形态特征在患有近视力引性巨病 (MTM),包括近视力 (MF) 的患者,使用光学连贯性断层扫描血管学 (OCTA).
  • 调查MTM相关的形态变化与视觉功能之间的相关性.

主要方法:

  • 一项横截面研究,涉及19只患有MF和部脱落 (FD) 的眼睛,37只患有MF但没有FD的眼睛,以及24个近视对照.
  • 用OCTA来评估表面和深层毛细血管中的黄斑血管密度 (VD),叶无血管区 (FAZ) 度量,视网膜厚度和体积.
  • 微波测量评估了黄斑敏感性 (MS),并分析了与最佳校正视敏度 (BCVA) 的相关性.

主要成果:

  • 与近视对照人群相比,患有MF (有或没有FD) 的患者表现出显著下降的偏面表面毛细管VD和深毛细管VD.
  • 在没有FD的MF组中,对体SCP VD与BCVA和MS在不同领域有显著的相关性.
  • 在患有FD的多发性肌痛组中,深层毛细管VD和视网膜厚度/体积与MS有关,而FD-300区域密度与BCVA相关.

结论:

  • 斑点输液与近视力拖拉性斑点病变中的功能性改变密切相关.
  • 通过OCTA测量的斑点血管密度 (VD) 可以作为监测MTM进展的宝贵生物标志物.
  • 这些发现可以帮助优化MTM患者的医疗和手术决策.
