bubble_chart Anatomy

• Muscles: orbicularis oculi, medial palpebral ligament, orbital fat body, and deep layer: medial rectus muscle.
• Nerves: Superior and inferior supratrochlear nerves, deep layer: ophthalmic branch of trigeminal nerve, superiorly: nasociliary nerve, laterally: eyeball, posterior to eyeball: optic nerve.
• Vessels: angular artery and vein, superior and inferior supratrochlear arteries and veins, deep layer superiorly: main trunk of ophthalmic artery and vein.

bubble_chart Manipulation

Have the patient lie supine and close eyes. One hand gently push the eyeball outward and downward to protect it. With the other hand, insert a thin, straight needle slowly and gently between the eyeball and the orbital wall to a depth of 0.2~1.5 cun. If resistance or pain is encountered, do not insert further. After withdrawing the needle, apply firm pressure to the area. Do not puncture the eyeball or press the needle too closely against the orbital wall. Avoid lifting, thrusting, or rotating the needle to prevent vascular injury and bleeding. If significant bleeding occurs, apply a cold compress to stop bleeding, followed by a warm compress to reduce swelling. Do not insert deeper than 1.5 cun, as this may damage the common tendinous ring around optic foramen and affect the optic nerve. If the needle exceeds 2 cun, the tip may reach superior orbital fissure, risking injury to the oculomotor, trochlear, abducens, and ophthalmic branch of trigeminal nerve. In severe cases, the needle may penetrate the superior orbital fissure and damage the brain, leading to serious consequences. Moxibustion is contraindicated.
