AIM To analyze the surgical results of a slipped medial rectus muscle (MRM) after hang back recession surgery for esotropia. METHODS Twenty-one patients who underwent re-exploration for diagnosed slipped muscle after hang back recession surgery were included in this retrospective study. Dynamic magnetic resonance imaging was performed to identify the location of the slipped muscle. Ocular mot...

purpose: to evaluate the clinical manifestations and surgical results in patients with double elevator palsy operated at labbafinejad eye center from 1993 to 2004. methods: the study was conduct on hospital records of 20 patients with double elevator palsy. patients were classified in three groups including primary elevator muscle palsy (9 subjects), primary supranuclear palsy with secondary in...

PURPOSE To evaluate the changes of refractive astigmatism after horizontal rectus muscle surgery in intermittent exotropic children. METHODS Sixty-nine exotropic patients were retrospectively reviewed. Of those, 35 patients received unilateral lateral rectus recession (BLR group, 35 eyes) and 34 patients received unilateral lateral rectus recession and medial rectus resection (R&R group, 34 e...

INTRODUCTION Endoscopic sinus surgery can result in serious extraocular muscle dysfunction. The medial rectus muscle is more frequently affected than other extraocular muscles. METHODS A transconjunctival subperiosteal medial orbitotomy was successful in retrieving a partially extirpated medial rectus muscle after endoscopic sinus surgery. RESULTS A previous attempt to localize this muscle ...

TEXT-BOOK examples ot strabismus fixus and of the retraction syndrome are not commonly encountered. Abnormal medial recti, however, showing some tendency towards the fibrosis or muscular thickening characteristic of such conditions, not uncommonly appear when ordinary squints are operated upon. Abnormal medial recti are usually found in congenital convergent squint. In most such cases there is ...

Simulated Brown syndrome is a term applied to a myriad of disorders that cause a Brown syndrome-like motility. We encountered a case of acquired simulated Brown syndrome in a 41-year-old man following surgical repair of fractures of both medial orbital walls. He suffered from diplopia in primary gaze, associated with hypotropia of the affected eye. We performed an ipsilateral recession of the l...

INTRODUCTION Patients with missing superior oblique (SO) tendons present with overelevation/underdepression in adduction. Unilateral cases often exhibit abnormal head postures, whereas in bilateral cases, there may be a marked V-pattern with upgaze exotropia. These patients may have craniosynostosis. METHODS Nine children with unilateral (n = 2) or bilateral (n = 7) absent SO tendons underwen...

PURPOSE To introduce a novel technique of inferior rectus recession operation to allow larger amounts of recession without causing lower lid retraction and to compare this method with the results obtained in standard inferior rectus recession. MATERIAL AND METHODS This study included 20 patients operated on in the authors' clinic. The median age of the patients was 24.5±18.6 (4-73) years and ...
