Central Retinal Artery, Anterior View

Description

Radiating from the orbit in an anterior perspective, the central retinal artery is followed as it enters the optic nerve and courses toward the posterior pole, where it supplies the inner (sensory) retina. Within the bony orbit, the vessel lies medial to the lateral orbital wall and deep to the anterior orbital contents, with its trajectory oriented posteriorly from the globe toward the optic canal. Surrounding orbital vessels are implied by the regional vascular network, including branches of the ophthalmic artery and accompanying venous channels, framed by the orbital rim, nasal bridge, and anterior maxilla. Clinical relevance is direct because central retinal artery occlusion produces sudden, painless monocular vision loss and remains an ophthalmic emergency where minutes matter for retinal survival. An anterior view helps anchor the artery’s relationship to the optic nerve head and ophthalmic circulation, a practical teaching point when discussing embolic sources (carotid atherosclerosis, cardiac thromboembolism) or iatrogenic events such as retrobulbar anesthesia complications. One vessel. One retina. Editors and instructors can place this artwork in neuro-ophthalmology and head and neck anatomy modules to illustrate how the ophthalmic artery’s intradural branch becomes the central retinal artery and why it functions as an end-artery to the inner retinal layers. It also fits stroke and vascular medicine content when linking transient monocular blindness (amaurosis fugax) to carotid disease, and in surgical or procedural training materials covering orbital injections, endoscopic sinus approaches near the medial orbit, and optic nerve decompression landmarks.
