AbstractWe present a case of bilateral isolated superior rectus paresis in a 13-year girl who presented with alternating exotropia and hypertropia. She demonstrated bilateral paresis of elevation in abduction with an overaction of both the contralateral yoke muscles, i.e. inferior obliques. Neuroimaging did not reveal a lesion along the pathway of the third nerve nor hypoplasia of the superior rectus muscle. We performed a bilateral lateral rectus recession on adjustable sutures with bilateral myectomy of the inferior obliques (weakening of contralateral yoke muscle). At 1 year, the patient is well aligned and happy. Isolated extraocular muscle pareses are rare events, which present occasionally to the strabismus surgeons and need to be looked out for if the patient's strabismus looks peculiar. We believe we are the first to report an isolated paresis of the superior rectus muscle in Pakistan.
