Tóm tắt

PURPOSE: To compare the surgical outcomes between superior oblique (SO) palsy (SOP) and masquerading SO palsy (mSOP). DESIGN: Comparative interventional case series. METHODS: Medical records of patients with SOP and mSOP were reviewed from 1991 to 2024. Palsy cases had maximum SO cross section in the hypertropic eye no more than 80% of that in the fellow eye, while mSOP cases had bilaterally symmetrical SO muscles on magnetic resonance imaging. Types of surgery and effect on hypertropia (HT) were compared between groups. RESULT: A total of 39 patients aged 38±20 (standard deviation) years had SOP and 18 aged 36±17 years had mSOP. Maximum palsied SO cross-section was 10.6±3.8mm CONCLUSION: Clinical characteristics and surgical effect are similar in mSOP and SOP. Conventional surgeries are comparably effective in both. This suggests that mechanism beyond SO muscle function drive head-tilt dependent cylcovertical strabismus.
