Abstract

Objective: To describe the clinical characteristics of binocular vision and analyze several factors related to binocular vision in patients with Basedow’s ophthalmopathy at Hanoi Medical University Hospital. Methods: A cross-sectional descriptive study was conducted on 37 patients diagnosed with Basedow’s ophthalmopathy who attended Hanoi Medical University Hospital from October 2024 to April 2025. Results: The study showed that strabismus was present in 62,16 of patients. The majority demonstrated normal ocular motility (78,38%). Among those with motility restriction, downward gaze was most frequently affected (12,16% of eyes), followed by inward gaze (10,81%). In contrast, upward and outward gaze limitations were less common, each accounting for 6,76% of eyes. Good stereopsis was observed in 40,54% of patients, an equal proportion had moderate stereopsis, and 18,92% had poor stereopsis. Most patients in the study did not have color vision problems (94,59%). More than half of the patients (51,35%) had abnormal near points of convergence. Age, smoking status, and disease severity and stage were closely associated with the degree of binocular vision impairment.
