In this case report, we present the rare occurrence of supernumerary extraocular muscles (SEOM) in a 35-year-old male with hyperthyroidism. SEOMs are unusual anatomical variations involving extraocular muscles that deviate from the typical muscle arrangement in the eye. While SEOMs are rare, they can have diverse clinical manifestations, including restrictive strabismus and lid abnormalities. In this case, the patient displayed right-sided lid retraction and an asymmetrical palpebral aperture, which raised concerns about a potential association with thyroid eye disease. However, imaging revealed that the SEOM was anatomically connected to the superior rectus muscle, possibly contributing to the observed lid retraction. Understanding the complexities of SEOM and its potential interactions with conditions like thyroid ophthalmopathy is crucial for accurate diagnosis and management. Further research is needed to fully comprehend the development and clinical impact of SEOMs due to their rarity and limited knowledge in the medical literature.
在本病例报告中，我们呈现了一名35岁甲状腺功能亢进男性罕见的额外眼外肌（SEOM）情况。SEOM是涉及眼外肌的异常解剖变异，偏离了眼睛中典型的肌肉排列。虽然SEOM很罕见，但它们可具有多种临床表现，包括限制性斜视和眼睑异常。在本病例中，患者表现为右侧眼睑退缩和睑裂不对称，这引发了对其与甲状腺眼病潜在关联的担忧。然而，影像学显示SEOM在解剖学上与上直肌相连，这可能是观察到的眼睑退缩的原因。了解SEOM的复杂性及其与甲状腺眼病等病症的潜在相互作用对于准确诊断和管理至关重要。由于SEOM在医学文献中罕见且知识有限，需要进一步研究以全面理解其发育和临床影响。
