The purpose of this study was to determine the effect of unilateral fronto-orbital advancement (FOA) or bilateral FOA on ocular aspects of plagiocephaly. A retrospective review of ocular findings in 16 patients with plagiocephaly was performed. Patients were divided into 2 groups: 12 patients who underwent bilateral FOA (bFOA) and 4 patients who underwent unilateral FOA (uFOA), and ocular findings were compared. One-half of patients showed strabismus in both groups, and all had exotropia. Hypertropia was found only on the same side of the plagiocephaly in 17% of the bFOA group and 25% of the uFOA group...

BACKGROUND: Progressive strabismus initially considered idiopathic may be caused by isolated schwannomas of motor nerves to extraocular muscles, detectable only on careful imaging. This study reviewed clinical experience of a referral practice in identifying schwannomas on magnetic resonance imaging (MRI). METHODS: We reviewed 647 cases imaged for strabismus to identify presumed cranial nerve schwannomas, identified by gadodiamide-enhanced, high-resolution surface coil orbital MRI and thin-section cranial MRI...

Isolated amyloid deposition in an extraocular muscle is a rare event but can be a presenting feature of systemic amyloidosis. A 67-year-old woman with an acquired exotropia and hypertropia was found to have unilateral diffuse extraocular muscle enlargement on magnetic resonance imaging. Owing to the progressive nature of her strabismus and the negative laboratory testing for thyroid disease, she underwent an extraocular muscle biopsy that revealed amyloid deposition. Further workup demonstrated a monoclonal gammopathy consistent with systemic amyloidosis...

Fibrous hamartoma of infancy is a rare, benign lesion of the superficial soft tissue, typically presenting within the first 2 years of life, and usually located on the upper extremities, axilla, and upper back. Lesions affecting the orbit have not been reported previously. We report the case of a 7-month-old boy with orbital fibrous hamartoma of infancy. He had a right hypertropia and a limitation of infraduction in the right eye. A mass on the right anteroinferior orbit involving the inferior rectus and inferior oblique muscles was seen on magnetic resonance imaging...

PURPOSE: To evaluate the clinical characteristics and surgical management of patients with an "inverted Brown pattern," which is defined clinically as a hypertropia with greatest deviation in down-and-in gaze of the higher eye, having the appearance of superior oblique muscle underaction but without significant inferior oblique muscle overaction. METHODS: The medical records of patients with this misalignment pattern who had cyclovertical muscle surgery at our institution from 2003 through 2015 were retrospectively reviewed; medical records were analyzed for pre- and postoperative motility patterns, fundus torsion, intraoperative findings, and type of strabismus surgery...

BACKGROUND: We present the outcomes of bilateral myectomy and tucking of the proximal end of the muscle for the treatment of asymmetric primary inferior oblique (IO) overaction. METHODS: This was a one-armed prospective cohort study. An ophthalmologist and orthoptist evaluated cases of primary IO muscle overaction presenting between January 2010 and December 2013. All eyes underwent bilateral myectomy and tucking of the proximal end of the IO muscle. Data were collected on ocular motility, the angle of deviation, postoperative complications, and status of hypertropia at 6 months postoperatively...

BACKGROUND: Heavy eye syndrome (HES) presents with esotropia and limited abduction due to superotemporal globe shift relative to the extraocular muscles. Sagging eye syndrome (SES) was originally described in nonmyopic patients exhibiting distance esotropia and cyclovertical strabismus with limited supraduction due to lateral rectus muscle inferodisplacement caused by degeneration of the lateral rectus-superior rectus (LR-SR) band. We hypothesized that SES might also cause strabismus in high myopia...

BACKGROUND: Children diagnosed with some forms of strabismus were recently found to have an increased risk of developing mental illness by early adulthood. The purpose of this case-controlled study was to determine if adults with non-paralytic forms of strabismus are similarly at an elevated risk for developing mental illness. METHODS: The medical records of all patients diagnosed as adults (≥ 19 years of age) with convergence insufficiency (CI) (n = 118), divergence insufficiency (DI) (n = 80), and small angle hypertropia (HT (n = 99) from January 1, 1985, through December 31, 2004, were retrospectively reviewed...

OBJECTIVE: To evaluate the effect of integrated anteriorization of inferior oblique muscle combined with recession of superior rectus to treat large hypertropia following absence of inferior rectus. METHODS: It was a retrospective case series study. Integrated anteriorization of inferior oblique muscle means transposing inferior oblique muscle 8-10 mm posterior to the insertion directly to original insertion of inferior rectus without myotomy. We reviewed 5 patients with absence of inferior rectus muscle, who treated by integrated anteriorization of inferior oblique muscle combined with recession of superior rectus...

BACKGROUND/AIMS: Graded vertical rectus tenotomy (GVRT) is postulated as effective for small-angle vertical heterotropia. We aimed to determine the dosing recommendations for GVRT in sagging eye syndrome (SES). METHODS: This was a retrospective, observational study of surgical outcomes for GVRT from 2009 to 2014 in a single surgeon's academic practice. There were 37 (20 women) patients of average age 68±10 (SD) years with comitant or incomitant hypertropia ≤10Δ caused by SES...

INTRODUCTION: Inferior oblique overaction (IOOA) can be primary or secondary, isolated or combined to other types of horizontal deviation, mostly with esotropias. Surgical weakening of IOOA means several techniques like; recession, myotomy, myectomy, anteroposition etc. GOALS: we analyzed the effect of inferior oblique muscle surgical weakening comparing two groups of patients with primary hypertropia. MATERIAL AND METHODS: In 5-years retrospective study, we observed 33 patients on which we did the surgical procedure of weakening inferior muscle overaction by two methods; recession and myotomy...

Inferior oblique muscle weakening is typically performed for overaction of the muscle. In this article, we review inferior oblique muscle anatomy, different weakening procedures, and recent surgical techniques that take advantage of the muscle's unique anatomy for the treatment of additional indications such as excyclotorsion and hypertropia in primary gaze.

PURPOSE: Previous strabismus appearance studies using images from real face photographs could not preclude the effect of other facial landmarks, such as position and contour of brow, nose, and facial outline, from pure effect of ocular deviation itself. With conceptualized drawings of eyes, we simulated strabismus deviation and collected the responses of observers. METHODS: The experiments consisted of three sessions: (1) one-eye, (2) two-eye cornea, and (3) two-eyelid deviation simulations...

Thyroid-related orbitopathy is a form of orbital inflammation associated with thyroid dysfunction, developing in many patients with Graves disease. Fibrosis of the inferior rectus muscle can lead to restricted elevation and vertical ocular misalignment, which may be improved by recessing this muscle. In some patients, vertical misalignment persists after surgical weakening of one or more vertical rectus muscles. In this case series, unilateral inferior oblique recession as a secondary procedure after inferior rectus recession reduced hypertropia in primary gaze from 9(Δ) ± 3(Δ) to 1...

BACKGROUND: Small hypertropic deviations due to inferior oblique muscle overaction may cause symptomatic diplopia and frustration because incomitant deviations render prism correction unsatisfactory. The several most common surgical options for inferior oblique weakening risk overcorrection of these smaller deviations. In this study we report the results of a "Z-myotomy" of the inferior oblique muscle to correct small incomitant hypertropias due to mildly overacting inferior oblique muscle...
