Purpose: We report the surgery outcome of three cases with congenital superior oblique palsy (SOP) with paradoxical head tilt
after conducting ipsilateral inferior oblique (IO) recession.
Case summary: Case 1 was a 4-year-old boy with right head tilt noted since about 3-4 months of age. He demonstrated right hypertropia of 6 prism diopters (PD). Case 2 was a 4-year-old girl who demonstrated left hypertropia of 6 PD and exotropia of 18
PD. She had shown intermittent left head tilt since about 3 months of age. Case 3 was a 8-year-old boy with right head tilt noted
since about 1 year of age. He demonstrated right hypertropia of 10 PD. Case 1 underwent left IO recession and left lateral rectus
recession. Case 2 and 3 underwent right IO recession.
Conclusions: Ipsilateral IO weakening was also the effective surgery in congenital SOP with paradoxical head tilt as well as in
the one manifesting usual head tilt.
