Dry Eyes or Keratitis Sicca is a major cause of tearing. Many times, it is under-diagnosed. Often the patients complain of foreign body sensation associated with redness and watery eyes. Depending on the degree of the dryness of the eye, the treatment starts with artificial tears for mild to moderate dry eye patients.
For the severe dry eye patients, treatment option could vary from non surgical placement of tear duct plugs to surgical tear duct occlusion to retain more tear.
An important group of facial traumas involve the eyelid; more importantly, within this group of eyelid traumas, the tear duct system can be damaged during these traumas. If not properly diagnosed and treated, the patient can have permanent tearing.
Dr. Lin Yang is specializes in treating these types of traumas.
Tears are made primarily by the lacrimal gland, wich is located in the upper inside corner of the upper eyelid. With each blink, tears are carried from the eye surface thru the lacrimal puncta to the lacrimal canaliculi and then to the lacrimal sac down to the nasolacrimal duct into the nose. Different problems along this trajectory can cause blockage of the tear duct system. These include blockage of the external tear drain (punctal stenosis), blockage of the portion of the tear drain in the eyelid (canalicular stenosis) and blockage of the tear drain in the nose (nasolacrimal duct obstruction).
Tearing is fairly common and when it improves with the use of artificial tears or only happens on rare occasions, it requires no further treatment. However, blockage of the tear drainage system externally, in the eyelid, or in the nose can require surgical correction.
Dr. Lin Yang is an expert in diagnosing and surgically managing abnormalities of the tear drainage system.
