Dr Schwartz and his team coaxed embryonic stem cells to become retinal pigment epithelium tissue which supports the rod and cone cells that actually respond to light

We first start our with this OCT scan, then, a manual segmentation step follows, where a doctor marks up this image to show where the most relevant parts, like the retinal fluids or the elevations of retinal pigments are.

我们先从OCT扫描开始，接下来跟进的是手工挑选步骤，由医生标注图片，标明和哪个部分相关，比如视网膜液或视网膜色素的高度。

视网膜的不同层级

视网膜又称视衣，是脊椎动物和一些头足纲动物眼球后部的一层非常薄的细胞层。它是眼睛里面将光转化为神经信号的部分。

视网膜含有可以感受光的视杆细胞和视锥细胞。这些细胞将它们感受到的光转化为神经信号。这些信号被视网膜上的其它神经细胞处理后演化为视网膜神经节细胞的动作电位。视网膜神经节细胞的轴突组成视神经。视网膜不但有感光的作用，它在视觉中也有重要作用。在形态形成的过程中，视网膜和视神经是从脑中延伸出来的。

视网膜上的血管的结构每个人都不一样，因此可以用来做生物特征识别。

Section of retina
Rods, cones and nerve layers in the retina. The front (anterior) of the eye is on the left. Light (from the left) passes through several transparent nerve layers to reach the rods and cones (far right). A chemical change in the rods and cones send a signal back to the nerves. The signal goes first to the bipolar and horizontal cells (yellow layer), then to the amacrine cells and ganglion cells (purple layer), then to the optic nerve fibres. The signals are processed in these layers. First, the signals start as raw outputs of points in the rod and cone cells. Then the nerve layers identify simple shapes, such as bright points surrounded by dark points, edges, and movement. (Based on a drawing by Ramón y Cajal, 1911.)
Distribution of rods and cones along a line passing through the fovea and the blind spot of a human eye[6]

The retina (UK /ˈrɛtɪnə/ RET-i-nə, US /ˈrɛtᵊnə/ RET-(ə-)nə, pl. retinae, /ˈrɛtiniː/; from Latin rēte, meaning "net") is the third and inner coat of the eye which is a light-sensitive layer of tissue. The optics of the eye create an image of the visual world on the retina (through the cornea and lens), which serves much the same function as the film in a camera. Light striking the retina initiates a cascade of chemical and electrical events that ultimately trigger nerve impulses. These are sent to various visual centres of the brain through the fibres of the optic nerve.
