Final answer:
The condition is called central retinal artery occlusion (CRAO), which is a medical emergency that can cause sudden and severe vision loss. It requires immediate attention to try to restore blood flow to the retina and prevent permanent vision loss.
Step-by-step explanation:
The condition that presents with sudden loss of vision in one eye and floaters in the visual field, and on fundoscopy, a fundus that's hard to visualize with obscure details is called central retinal artery occlusion (CRAO).
CRAO occurs when there is a blockage in the central retinal artery, which is the main blood vessel that supplies blood to the retina. When the blood flow to the retina is blocked, it can cause sudden and severe vision loss.
This condition is considered a medical emergency and requires immediate attention to try to restore blood flow to the retina and prevent permanent vision loss.
