Introduction: This study aims to analyze risk factors for ocular surface irritation symptoms in patients with non-corneal-damage inactive mild and moderate-to-severe Graves' orbitopathy (GO).
Methods: This retrospective study enrolled 307 patients with non-corneal-damage inactive GO admitted to Sun Yat-sen Memorial Hospital from April 2017 to September 2023. The activity and severity of GO were evaluated using the Clinical Activity Score (CAS) and the European Group on Graves' Orbitopathy (EUGOGO) classification, respectively. Multivariate logistic regression analysis was performed to analyze risk factors for ocular surface irritation symptoms.
Results: Among patients with inactive GO, for mild cases, CAS (P < 0.001), upper eyelid lag (P = 0.049), and extraocular muscle involvement (P = 0.019) in the symptomatic group were greater than those in the asymptomatic group, and multivariate logistic regression analysis demonstrated that upper eyelid lag (P = 0.048), CAS 1 (P < 0.001), CAS 2 (P = 0.005), and extraocular muscle involvement (P = 0.029) were risk factors for ocular surface irritation symptoms; for moderate-to-severe cases, CAS (P = 0.004), extraocular muscle involvement (P < 0.001), marginal reflex distance 1 (MRD1) (P = 0.030), and thyroid-stimulating hormone (TSH) (P = 0.034) in the symptomatic group were greater than those in the asymptomatic group, while multivariate logistic regression analysis indicated that extraocular muscle involvement (P = 0.018) and MRD1 (P = 0.012) were risk factors for ocular surface irritation symptoms.
Conclusion: In non-corneal-damage inactive mild and moderate-to-severe GO, eyelid malposition and periocular muscle inflammation are risk factors for ocular surface irritation symptoms.

Graves’ orbitopathy is the most common outward sign of Graves’ disease. Patients with inactive Graves’ orbitopathy often complain of ocular surface irritation symptoms. This study retrospectively collected clinical data from 307 patients with inactive Graves' orbitopathy and no concurrent corneal damage. The aim was to analyze risk factors for ocular surface irritation symptoms. Upper lid lag, eye movement disorder, and the Clinical Activity Score were found to be risk factors for mild cases. Eye movement disorder and the distance between the upper eyelid margin and corneal reflection point were risk factors for moderate-to-severe cases. To reduce symptoms, it may be helpful to treat inflammation around the eyes and address any eyelid abnormalities.
