简要总结
Thyroid eye disease (TED) is an autoimmune disease that affects the eye area. The disease presents with a variety of physical findings, including bulging of the eyes (proptosis), upper and lower eyelid retraction, and swelling/inflammation of the eye itself.
The disease passes through two phases: active and inactive. The active phase lasts between 18 and 24 months. During this phase, TED signs and symptoms generally worsen and then often improve. The inactive phase follows, during which the signs and symptoms of TED cease to improve and usually stabilize.
Lid retraction is a cardinal sign of TED. In addition to potentially causing cornea damage due to improper lid closure, lid retraction is also very troublesome for patients due to its cosmetic appearance. The precise pathophysiology of lid retraction is poorly understood, but a leading hypothesis is that it occurs due to scarring and fibrosis in the muscles that lift the eyelid.
Currently, the definitive treatment for lid retraction is surgery, which can be used to lengthen the lid itself or remove inflamed tissue from behind the eye, thus causing the eye to bulge less. In cases when patients first present to their physician with corneal ulceration or compression of the optic nerve, surgery may be performed immediately. However, in most instances, surgical procedures are delayed until the active stage of the disease has passed. Thus, most patients must endure the cosmetic and irritant symptoms of TED for up to two years.
Hyaluronic Acid Gels (HAG) have been FDA approved for the treatment of facial rhytids (wrinkles). They are injected under the skin and work by increasing volume. Recently, some smaller retrospective research studies have shown that HAG is also effective in correcting upper and lower eyelid retraction in TED. Hence, HAG may be for patients with active stage TED. It is also thought that if employed early in active phase disease, HAG may also help to decrease the severity of associated symptoms and reduce the need for surgery.
The purpose of the current investigation is to define the clinical utility of HAG correction of upper eyelid in active TED in terms of anatomic (lid position), quantitative (corneal dry eye signs) and qualitative effects (symptom severity and thyroid related quality of life).

入选标准
- •Active stage TO as determined by symptom onset of under 9 months.
- •Upper eyelid retraction of 1mm or greater in one or both eyes.
- •Complaints of either significant ocular symptoms (despite appropriate use of ocular lubricants), or cosmetic deformity associated with the eyelid retraction.
排除标准
- •Age less than 21 years: due to lack of data on safety for HAG fillers in pediatric population
- •Age over 65 years of age: as HAG filler effect may be different in this population
- •Are pregnant or nursing: as there is little safety data on potential teratogenicity of HAG fillers
- •Have a demonstrated allergy to HAG fillers or lidocaine
- •Have a current infection, skin sore, pimple, rash, hive or cyst over the injection site: to avoid worsening the infection or transmitting it
- •Have a bleeding disorder or currently taking blood thinning medications such as Coumadin, heparin or acetylsalicylic acid on a daily basis.
