Figure 1. Process of pathological change.

A: The rod cells, retinal pigment epithelial cells, and photoreceptors undergo denaturation and proliferation; B: The proliferating retinal pigment epithelial cells and macrophages migrate towards the vascular layer within the retina, in close proximity to the veins; C: The optic vessel's outer membrane exhibited hyalinoid degeneration and thickening; D: Choroidal vascular sclerosis of different degrees; E: Occlusion of the central artery of the optic nerve can result in optic neuropathy.
