Abstract

Introduction: Isolated inferior oblique palsy is one of the rarest among extra ocular muscle palsies. In addition to posing a diagnostic challenge, multiple surgical techniques have been described in its surgical treatment.

Case Report: A 23-year old female presented with unilateral right eye hypotropia and diminished vision. Following detailed evaluation, she was diagnosed with right eye inferior oblique palsy with A pattern exotropia and strabismic amblyopia. We performed a combined surgical procedure involving a partial Knapp's procedure with augmentation (using superior halves of medial and lateral recti), LR recession (using inferior half of split LR) and posterior tenectomy of superior oblique (PTSO), which resulted in a satisfactory postoperative outcome.

Conclusion: IO palsy is a rare condition, which requires to be differentiated from neurological causes, Brown syndrome and skew deviation. Both exotropia and hypotropia have been corrected in the same procedure, using split halves of only two horizontal recti muscles, thus preventing possibility of anterior segment ischemia. This combination, along with LR recession, for exotropia and PTSO, produces satisfactory alignment.
