Blood vessel in periocular region

The term "Blood vessel in periocular region" refers collectively to the network of arteries, veins, and capillaries supplying the tissues around the eye—including eyelids, orbital fat, muscles controlling eye movement, skin around the orbit ("periocular"), conjunctiva, sclera, choroid, ciliary body, iris—and draining these areas. The main arterial supply derives from branches of both internal carotid artery (via ophthalmic artery) and external carotid artery. Key branches include: *Arteries* - Ophthalmic artery branches: lacrimal artery; supraorbital/supratrochlear arteries; medial palpebral arteries; long/short posterior ciliary arteries; anterior ciliary arteries. - Marginal arcades formed by superior/inferior marginal vessels supply upper/lower eyelids. *Veins* - Central retinal vein drains retina. - Superior/inferior ophthalmic veins drain orbital contents/periocular structures into cavernous sinus. These vessels play essential roles in maintaining ocular health by delivering oxygen/nutrients and removing waste. They are not considered therapeutic targets themselves but can be involved incidentally—especially as *danger zones* for inadvertent intravascular injection during cosmetic procedures like dermal fillers. Compromise or injury to these vessels can result in serious complications including ischemia or blindness. Because this is an **anatomical grouping** rather than a discrete molecule/receptor/protein/enzyme/transporter/etc., it is **not considered a therapeutic target** under standard pharmacological definitions. Therefore, the entry is marked **is_incorrect: true**, since it does not correspond to a canonical druggable molecular entity. If you need information on specific molecules within this system—such as "Vascular endothelial growth factor receptor," "Endothelin receptor," etc.—please specify further.
