【Location】On the face，directly below the pupil，between the eyeball and the infraorbital ridge.
【Manipulation Method】Puncture slowly and perpendicularly 0.3-0.7 cun closely along the infraorbital ridge，without lifting and thrusting manipulation.
【Indications】Pain and swelling in the eyes，lacrimation with wind，twitching of eyelids，night blindness，myopia，deviated mouth and eye.
【Stratified anatomy】（Fig.1-6，Fig.1-9）
（1）Skin The skin is distributed by infraorbital n..
（2）Subcutaneous tissue There are branches of infraorbital n.，zygomatic branches of facial n.，branches or tributaries of infraorbital a. ＆ v..
（3）Orbicularis oculi The orbicularis oculi is located in the deep surface of superficial fascia around the rima oculi.
（ 4）Adipose body of orbit The adipose body of orbit is composed of the adipose tissue which is filled among the intraorbital eyeball，the ocular muscle and the periorbita.
（5）Obliquus inferior The obliquus inferior is located below the eyeball.
【Adjacent structures】
（1）Rectus inferior The rectus inferior is located below the eyeball.
（2）Infraorbital groove，infraorbital canal and their content There is a vertical infraorbital groove in the middle part of the paries inferior orbitae from backward to forward.And the infraorbital groove still continues forward to puncture through the mfraorbital canal of paries inferior orbitae and the opening is located in the infraorbital foramen under the infraorbital margin.The infraorbital a.，v.and n.pass by the infraorbital groove as well as the infraorbital canal and go through the infraorbital foramen to the subcutaneous region.

【Cautions】If the needling position is extremely close to the paries inferior orbitae and the depth of needling is more than 0.4 cun，the infraorbital groove can be needle-inserted so that the infraorbital a.and v.can be injured and the ecchymosis of eyelid is occurred.Hence，when there is needle-inserting，the needle point shall not be so close to the paries inferior orbitae that damages the vessels.While there is removing the needle，there shall be with a gentle manner and half minute’s pressing of cotton ball for avoiding bleeding.If the position of needling is extremely close to eyeballs，the wall of eyeball can be needle-inserted through the rectus inferior.Needle-inserting in the eyeballs is the more serious situation.If the depth of needling is more than 1.9 cun，the common tendinous ring，the optic n.，the superior orbital fissure and its deep structure can be injured.If the common tendinous ring is needle-inserted，there is a viscous feeling of needle point.If the optic nerve is needle-inserted，the complaints of patients are the blurred vision（stimulation of the optic nerve），headache and dizziness（stimulation of the dura mater），as well as nausea and vomiting in serious condition.If the depth of needle point is more than 2 cun with the extreme posterior-lateral position of needling，the needle point can arrive in the superior orbital fissure.At this moment，not only can the nerves and vessels passing through the superior orbital fissure be needle-inserted，but the cavernous sinus in the middle cranial fossa can also be injured by needling through the superior orbital fissure.Even there is the intracranial hemorrhage caused by needle-inserting in the front end of temporal lobe of brain accompanying with the following symptoms: serious dizziness，headache，nausea，vomiting，even shock and death.
