Introduction: Thyroid eye disease (TED) is an autoimmune condition producing ocular pain, dysmotility, and ocular structure and function changes. As disease activity changes, redness, swelling, and pain can improve, but eye comfort, appearance, and motility alterations often persist. There are limited data on chronic TED patient-reported outcomes. This study examined chronic US TED patient-reported symptoms and quality of life (QOL). Methods: Existing data from an online survey regarding chronic TED signs/symptoms and patient QOL were retrospectively examined. The Graves' Ophthalmopathy QOL instrument (GO-QOL; 0–100, 100 = highest QOL) evaluated overall, appearance, and vision-related QOL. Influencing factors were examined by stratifying patients into low (overall QOL ≤ 50), moderate (> 50 and < 75), and high (≥ 75) QOL categories. Results: One hundred patients (47 women, 81 Caucasian, 45.2 ± 7.6 years) were included. The duration of inactive TED was 3.0 ± 4.6 years and total duration of TED was 5.8 ± 5.9 years. Patients reported an average of 20 doctor visits/year and high prevalence of anxiety (34%) and depression (28%). Prior TED treatments for the polled population included systemic corticosteroids during active TED (25%), orbital radiation (5%), and surgery (25%). The overall GO-QOL score was 60.5 ± 21.8 (vision-related: 58.6 ± 24.0, appearance-related: 62.3 ± 25.1). Patients with low QOL more frequently reported hypothyroidism, anxiety, and a larger number of chronic TED signs/symptoms (average: 4.2). Compared to high QOL patients, low QOL patients had more pain (39% vs. 13%), blurry vision (30% vs. 17%), and diplopia (27% vs. 3%, all p ≤ 0.025). Additionally, the low QOL group more often had TED-specific surgical history (45% vs. 10%, p = 0.002), more often reported disability/unemployment (21% vs. 3%, p = 0.055), and had a higher number of doctor visits (40 vs. 5 visits/person/year, p < 0.001). Conclusion: TED severely impacts patient QOL, despite becoming stable and chronic. Patients reported vision and appearance impairment and psychosocial impact long after acute TED had subsided. Plain Language Summary: Thyroid eye disease (TED) occurs when loss of immune tolerance results in orbital and retro-orbital inflammation. Fat and muscle tissue can swell severely, causing debilitating symptoms, including pain around/behind the eyes, eye movement abnormalities, bulging eyes (proptosis), and double vision (diplopia), manifesting in appearance and vision quality of life (QOL) changes. Some improvement can occur as inflammation quiets and TED becomes chronic/inactive. However, appearance and visual changes often remain due to persistent proptosis and eye muscle and eyelid changes. This study examined TED symptoms and QOL in 100 chronic TED patients. They answered questions about symptoms, how TED affected them, and their medical care. The average duration of TED was 6 years (3 years inactive), patients had an average of 20 TED-related doctor visits/year, and nearly one-half (42%) of patients reported having anxiety and/or depression. Prior TED treatments included steroids (25% when TED-related inflammation was present), orbital radiation (5%), and surgery (25%). Disease-specific QOL scores (average score: 60.5 of 100) indicated that these chronic patients reported similar QOL impact as those with moderate-to-severe, active disease. Compared with the least impacted group, the most impacted patients reported higher rates of hypothyroidism (18% vs. 0%), anxiety (48% vs. 17%), disability/unemployment (21% vs.3%), number of doctor visits (40 vs. 5 visits/person/year), pain (39% vs. 13%), blurry vision (30% vs. 17%), diplopia (27% vs. 3%), and surgical treatment for TED (45% vs. 10%). This study demonstrates that QOL continues to be severely impacted by TED long after TED-related inflammation has quieted. [ABSTRACT FROM AUTHOR]

The data as it appears in the abstract (results section) is correct: "The overall GO-QOL score was 60.5 ± 21.8 (vision-related: 58.6 ± 24.0, appearance-related: 62.3 ± 25.1)." Correction to: Ophthalmol Ther (2021) 10:975-987 https://doi.org/10.1007/s40123-021-00385-8 The original publication contained an error regarding the appearance-related and vision-related QOL scores. The first sentence under the subheading "Effect of Thyroid Eye Disease on Quality of Life and Mental Health" should read: "Patient QOL was markedly impaired by TED at the time of survey, as indicated by an overall GO-QOL score of 60.5 ± 21.8, an appearance sub-score of 62.3 ± 25.1, and a visual function sub-score of 58.6 ± 24.0.".

To evaluate teprotumumab safety/efficacy in patients with thyroid eye disease (TED) who were nonresponsive or who experienced a disease flare. The Treatment of Graves' Orbitopathy to Reduce Proptosis with Teprotumumab Infusions in an Open-Label Clinical Extension Study (OPTIC-X) is a teprotumumab treatment and re-treatment trial following the placebo-controlled teprotumumab Phase 3 Treatment of Graves' Orbitopathy (Thyroid Eye Disease) to Reduce Proptosis with Teprotumumab Infusions in a Randomized, Placebo-Controlled, Clinical Study (OPTIC) trial. Patients who previously received placebo (n = 37) or teprotumumab (n = 14) in OPTIC. OPTIC nonresponders or those who flared (≥2-mm increase in proptosis, ≥2-point increase in clinical activity score [CAS], or both) during follow-up were treated for the first time (previous placebo patients) or re-treated with teprotumumab in OPTIC-X with 8 infusions over 24 weeks. Proptosis response and safety. Secondary outcomes included proptosis, CAS, subjective diplopia, and quality-of-life. Thirty-three of 37 placebo-treated OPTIC patients (89.2%) became proptosis responders (mean ± standard deviation, –3.5 ± 1.7 mm) when treated with teprotumumab in OPTIC-X. The responses were equivalent to the OPTIC study. In these responders, proptosis, CAS of 0 or 1, and diplopia responses were maintained in 29 of 32 patients (90.6%), 20 of 21 patients (95.2%), and 12 of 14 patients (85.7%), respectively, at follow-up week 48. The median TED duration was 12.9 months versus 6.3 months in those treated with teprotumumab in the OPTIC study. Of the 5 OPTIC teprotumumab nonresponders re-treated in OPTIC-X, 2 responded, 1 showed a proptosis reduction of 1.5 mm from OPTIC baseline, and 2 discontinued treatment early. Of the OPTIC teprotumumab responders who experienced flare, 5 of 8 patients (62.5%) responded when re-treated (mean proptosis reduction, 1.9 ± 1.2 mm from OPTIC-X baseline and 3.3 ± 0.7 mm from OPTIC baseline). Compared with published double-masked trials and their integrated follow-up, no new safety signals were identified. Mild hearing impairment was reported; 4 events occurred during the first course of treatment, and 2 events reoccurred after re-treatment. Patients with TED of longer disease duration responded similarly to those treated earlier in the disease course. Patients with an insufficient initial response or flare may benefit from additional teprotumumab therapy. No new safety risk was identified; however additional postmarketing pharmacovigilance is ongoing. [ABSTRACT FROM AUTHOR]
