Table 1 Diagnostic criteria for central retinal artery occlusion.
| Clinical manifestation | Sudden, painless monocular vision loss |
|---|---|
| Signs | The pupil of the affected eye is moderately dilated, with a significantly delayed or absent direct pupillary light reflex, while the indirect pupillary light reflex is intact and responsive |
| Fundus manifestations | Retinal edema, cherry-red spots, segmental slow blood flow in weakened retinal arteries, and no abnormalities in the optic nerve head |
| Fundus fluorescein angiography | During the acute phase, it shows prolonged filling times of both the occluded retinal arteries and veins, thinning of both arterial and venous blood flow, and an extended retinal circulation time. In the recovery phase of the disease, while retinal function may have been significantly impaired, blood perfusion can recover. At this point, there may be no obvious abnormal findings |
