Eye Stroke: Blindness Looms in Hours
11 Dec
Summary
- Central retinal artery occlusion causes sudden, severe vision loss.
- Blindness can become irreversible within three hours of occlusion.
- This condition is equivalent to a stroke or heart attack for the eye.
An urgent eye condition known as central retinal artery occlusion (CRAO) poses a severe threat to vision. This emergency occurs when the artery supplying blood to the retina becomes blocked, drastically cutting off vital oxygen and nutrients.
The consequences of CRAO are swift and severe. Medical professionals stress that without immediate treatment, typically within the first two to three hours, the resulting blindness is often irreversible. This emphasizes the critical nature of prompt medical attention for CRAO.
Comparatively, CRAO is likened to a stroke or heart attack, but affecting the eye. When the central artery is occluded, the retina, responsible for sight, begins to die. This cellular death leads to the complete and permanent loss of function in the affected eye.
