Which vessels supply blood to the eye from the internal carotid artery?

The ophthalmic artery is the correct answer as it is the primary vessel that branches from the internal carotid artery to supply blood to the eye. This artery plays a crucial role in providing oxygen and nutrients to the various structures within the eye, including the retina, optic nerve, and ocular muscles.

The ophthalmic artery enters the orbit through the optic canal along with the optic nerve and gives rise to several important branches that ensure adequate blood flow to the eye and its associated tissues, which are essential for maintaining vision and overall eye health.

In contrast, the other vessels listed do not supply blood to the eye directly. The frontal artery primarily supplies the forehead and scalp, the occipital artery supplies blood to the back of the head and neck, and the temporal artery is mainly responsible for the blood supply to the side of the head. Therefore, the specific connection of the ophthalmic artery to the internal carotid artery and its subsequent branches to the eye solidify its role as the correct answer to this question.
