2023年1月25日 · 因为生物测量仪主要是测量到视网膜色素上皮层（RPE）的信号，而真正的眼轴的数值是到视网膜內界膜（ILM）的数值，因此报告出具的眼轴的数值是会减去视网膜的厚度200μm。

Segmentation included internal limiting membrane (ILM), outer nuclear layer/Henle fiber layer complex (ONL/HFL), EZ, and the retinal pigment epithelium (RPE). The output included metrics for the inner retina (ILM-OPL/HFL), outer retina (ONL/HFL-RPE), EZ-RPE area and volume, and en face EZ mapping.

ILM是内界膜 RPE是视网膜色素上皮细胞层 眼后节分层可参考下图：

视网膜色素上皮 (RPE)是由排列在视网膜最外层的一层规则的多边形细胞组成。 RPE的外侧连接布鲁赫膜和脉络膜，内侧连接光感受器细胞的外节。 外侧呈现出基底内折叠样，这增加了细胞表面积，促进物质交换。 位于布鲁赫膜最内层的半桥粒与基底膜紧密相连。 RPE细胞内部有延伸到光感受器外节 (POS)之间的微绒毛结构，参与了RPE的吞噬功能。 单层RPE与缝隙连接之间形成的紧密连接控制着物质的运动，同时与布鲁赫膜和脉络膜在视网膜外侧形成 脉络膜-血-视网膜屏障。 …

Boundary locations corresponding to the presumed inner limiting membrane (ILM), inner/outer segment junction (IS/OS), anterior border of retinal pigment epithelium (RPE), and Bruch’s membrane (BM) were manually identified by trained graders, and the layer boundaries were fit using spline interpolation.

Retina thickness （RT）：视网膜厚度 在报告上这个数字是一个系统常数。 因为生物测量仪主要是测量到视网膜RPE层的信号，而真正的眼轴的数值是到视网膜內界膜的数值，因此报告出具的眼轴的数值是会减去视网膜的厚度200μm。

Automatic measurement of retinal thickness performed on ILM and RPE lines in OCT scans to enable ophthalmologists to assess retina health.

The classic definition is the distance between ILM and the first highly reflective interface (presumably IS-OS) in the OHRB (Total retinal thickness (ILM to IS-OS) ). A second definition is the distance between ILM and the second highly reflective interface (presumably RPE) in the OHRB (Total retinal thickness (ILM to RPE) ).

2021年5月14日 · The proposed method for segmentation of retinal layers (ILM, RPE, and BM) in OCT images have four steps: pre-processing, the definition of the area of interest, initial segmentation, and final segmentation.
