Temporal arteritis, also known as giant cell arteritis, is an inflammatory condition affecting the medium and large arteries, particularly the temporal arteries. One of the most critical complications that can arise from temporal arteritis is blindness in the affected eye. This occurs due to the inflammation leading to reduced blood flow to the optic nerve or branch of the ophthalmic artery.

Immediate treatment with high-dose corticosteroids is essential to reduce inflammation and restore blood flow, thereby preventing irreversible damage to the optic nerve. If treatment is delayed, the risk of permanent visual loss increases significantly, which is why awareness and prompt intervention are vital in managing this condition, especially in older adults.

The other conditions listed, while they may be associated with temporal arteritis or its complications, do not pose the immediate risk of permanent loss or damage as blindness does, making the prevention of blindness the most critical aspect of treatment initiation.
