Thyroid eye disease (TED) is an autoimmune condition, most often linked to Graves disease, that inflames the tissues around the eyes. It can make the eyes bulge (proptosis), cause double vision, and change a person’s appearance. Teprotumumab (Tepezza) was the first FDA-approved biologic medicine for moderate-to-severe TED. A new systematic review in the American Journal of Ophthalmology looked at how it performs in trials and in everyday practice.
What the review included
Researchers at Peking University First Hospital searched four databases through August 2026. They included 36 studies: 6 randomized controlled trials (4 of teprotumumab and 2 of similar medicines) and 30 real-world studies of intravenous teprotumumab in adults.
Benefits
- Eye bulging: in randomized trials, patients on teprotumumab were about 4.6 times as likely as those on placebo to have a meaningful reduction. In real-world studies, 82% of patients responded.
- Double vision: trials favored teprotumumab about 2 to 1, and 60% of real-world patients improved.
Side effects to know about
- High blood sugar: more frequent with teprotumumab in trials and seen in 17% of patients in real-world studies.
- Hearing problems: also more frequent in trials, and reported in 18% of real-world patients.
The authors conclude that teprotumumab improves bulging and double vision across study types, but that blood sugar and hearing effects in real-world use call for careful patient selection and monitoring.
If you have thyroid eye disease
- Ask whether your TED is active (inflamed) or stable; treatment choices differ.
- If teprotumumab is considered, ask about blood sugar checks, especially if you have diabetes or prediabetes, and about a baseline hearing test.
- Report ringing in the ears, muffled hearing, or excessive thirst during treatment.
- Not smoking is one of the most important steps for TED.
- Protect the eye surface with lubricating drops if your lids do not close fully.
TED is managed by oculoplastic or orbital specialists together with endocrinologists; ask your eye doctor for a referral. For more reading, see malibulasik.com.
