- Detailed Description
Thyroid Eye Disease (TED) is a complex autoimmune disorder that causes substantial morbidity. It can result in enlargement and scarring of orbital fat and muscles with orbital disfigurement, diplopia, and even vision loss. Although the disease is self-limited following an inflammatory phase of 12 - 18 months, its long-term changes to periocular tissues may have a significant effect on the quality of life, mental health, and socioeconomic status of patients.
Most patients with TED (\>90%) have Graves' disease, which is an inflammatory autoimmune condition that is caused by thyrotropin (TSH) receptor autoantibodies. Graves' disease is common around the world and it mainly affects middle-aged women with an overall prevalence of 0.5%.
Several validated assessment scores are used to assess different components of the disease. The two main current TED classifications are from the European Group on Graves Orbitopathy (EUGOGO); and Vision, Inflammation, Strabismus, Appearance (VISA). EUGOGO has introduced one score for clinical activity (CAS) and one for severity "Clinical Severity Score" (CSS). The baseline CAS asses 7 subjective symptoms and inflammatory signs with 3 additional points in follow-up for increased proptosis, decreased ocular motility, or decreased visual acuity (the CAS 10- point scale). In comparison, CSS evaluates the magnitude of the exophthalmometer or proptosis values, lid retraction, diplopia grades, and corneal involvement.
Periorbital inflammation can cause swelling, fatty infiltration, and scarring of the eyelid muscles, resulting in eyelid retraction and upper scleral exposure, which are the most common clinical features of TED.
Several treatment options have been described for correction of eyelid retraction (ELR), including local steroid, Botox and filler injection, and surgeries in the fibrotic stage. Although surgical treatment remains an effective option, the outcomes may be unpredictable. In addition, there are some situations where surgery is inappropriate or contraindicated, where temporary or definitive measures are required during the active phase of the disease, or where patients may prefer less invasive options.
Systemic steroid therapy is a well-established form of immunosuppressive treatment for TED. There have been reports showing promising results with local steroid injection for the treatment of upper eyelid retraction (UER), There are also some reports about the retrobulbar and periocular injection of steroids for management of proptosis in TED.

- Primary Outcome Measures
Name Time Method to measure the change in proptosis in mm using Hertel's exophthalmometer in group B after retrobulbar injection of different types of steroid 4 minutes The technique will be considered; 1) Effective if the reading of Hertel's exophthalmometer reached the normal value (16±2mm), 2) Partially effective if the proptosis was improved but did not reach the normal values, 3) Ineffective of no improvement occured in proptosis
to measure the change in MRD1 in mm using slit lamp biomicroscope in all groups after peri-levator injection of different types of steroid 2 minutes The technique was considered; 1) Effective if the MRD1 reached the normal value\< or= 4.5mm, 2) Partially effective if the MRD1 was improved but did not reach the normal values, 3) Ineffective if no improvement occured in MRD1
- Secondary Outcome Measures
Name Time Method to document any change in size of superior rectus levator complex and other extra-ocular muscles 4 minutes measuring size of superior rectus levator complex and other extra-ocular muscles before and after injections by orbital imaging techniques (CT or MRI).
