Criteria
Inclusion Criteria:

1. Active Thyroid Eye Disease

2. Clinical Activity Score (CAS) 3 and 5

3. Phakic and pseudophakic eyes are allowed in the study.

4. Willing and able to provide written informed consent after the nature of the study has
been explained, and prior to any research-related procedures

5. Willing and able to comply with clinic visits and study-related procedures

6. Only one eye will be enrolled. The worse eye (demonstrating any of these features:
worse HVF results, worse restricted motility, worse visual acuity, worse edema, worse
proptosis, worse eyelid retraction) will be enrolled. If both eyes are equivalent, we
will enroll the non-dominant eye.

Exclusion Criteria:

1. History of orbital, strabismus, or eyelid surgery or orbital radiation

2. Optic neuropathy or other vision-threatening signs

3. Patients currently on systemic or topical steroids. If they received steroids in the
past, they would require a 6 week washout period and the cumulative dose of steroids
must be less than 1 gram of methylprednisolone (or equivalent). During the washout
period we will contact patients by phone weekly to monitor their safety and address
any concerns they may have related to no longer taking steroids .

4. Systemic steroid therapy within 6 weeks of Day 0

5. Patients who have received intraocular anti-VEGF medications within 1 year of
screening

6. Patients who have a history of receiving systemic anti-VEGF

7. Presence of other retinal vascular diseases (diabetic retinopathy, vein occlusion)
that could affect the VEGF levels within the eye

8. History of stroke or prior myocardial infarction

9. Known hypersensitivity to aflibercept

10. Infectious conjunctivitis, keratitis, or endophthalmitis of either eye

11. Presence of a glaucoma shunting or filtration device that is subconjunctival

12. Previous participation in any studies of investigational drugs within 1 month
preceding Day 0

13. Any clinically significant acute or chronic medical condition that would preclude
participation in a clinical study

14. Pregnant or breast-feeding women

15. Sexually active men* or women of childbearing potential** who are unwilling to
practice adequate contraception during the study (adequate contraceptive measures
include stable use of oral contraceptives or other prescription pharmaceutical
contraceptives for 2 or more menstrual cycles prior to screening; intrauterine device
[IUD]; bilateral tubal ligation; vasectomy; condom plus contraceptive sponge, foam, or
jelly, or diaphragm plus contraceptive sponge, foam, or jelly)

16. History of hyaluronidase (HA) injection after the diagnosis of thyroid eye disease
