Hyeshin Jeon, Heeyoung Choi
PURPOSE: To investigate the length of time required for diagnosing consecutive esotropia rather than initial overcorrection and examine risk factors for persistent postoperative esotropia after intermittent exotropia surgery. METHODS: This is a retrospective case series in a tertiary medical center. Fifty consecutive patients with postoperative esotropia ≥6 prism diopters at 1 week following exotropia surgery, managed with nonsurgical management and followed up for more than 6 months from 2014 to 2015, were included...

PTRH2 is an evolutionarily highly conserved mitochondrial protein that belongs to a family of peptidyl-tRNA hydrolases. Recently, patients from two consanguineous families with mutations in the PTRH2 gene were reported. Global developmental delay associated with microcephaly, growth retardation, progressive ataxia, distal muscle weakness with ankle contractures, demyelinating sensorimotor neuropathy, and sensorineural hearing loss were present in all patients, while facial dysmorphism with widely spaced eyes, exotropia, thin upper lip, proximally placed thumbs, and deformities of the fingers and toes were present in some individuals...

PURPOSE: To evaluate the result of using intraoperative botulinum toxin A (BTA) as an adjunct to monocular recession-resection surgery in the management of large-angle sensory strabismus. METHODS: The medical records of patients diagnosed with sensory strabismus with constant large-angle strabismus were reviewed retrospectively to identify those who underwent monocular recession-resection surgery combined with 5 units of BTA injection into the recessed muscle of the nonfixating eye...

We report two patients, one with congenital dystrophic medial rectus muscles and one with absence of the medial rectus muscles; in addition, one of them had absence of the lateral rectus muscles. While absence of the superior oblique and superior rectus has been more commonly reported in literature, especially with craniofacial syndromes, our patients were nonsyndromic. Considering the risk of anterior segment ischemia, correction of the large-angle exotropia was performed by horizontal rectus muscle surgery where possible, along with transfer of the superior oblique tendon to the superior part of the normal medial rectus muscle insertion area to create a tethering effect with a good outcome...

BACKGROUND: Surgical treatments for large-angle exotropia include bilateral lateral rectus recession, recession-resection procedures, and three- and four-muscle surgery. Undercorrection and limitation of abduction are common complications of these procedures. This study reports the results of bilateral medial rectus resection as a first procedure for primary large-angle exotropia. METHODS: The medical records of patients who underwent bilateral medial rectus resection for angles ≥60(Δ) in the period from 2006 till 2016 with a minimum follow-up period of 6 months were reviewed retrospectively...

PURPOSE: To report strabismus surgery outcomes in eyes with prior implantation of glaucoma drainage devices (GDD). METHODS: The medical records of patients who underwent strabismus surgery for ocular misalignment that developed after implantation of a GDD over a 13-year period at a single institution were examined retrospectively. Patient characteristics, deviation types, preoperative measurements, surgical procedures, and postoperative measurements were analyzed...

BACKGROUND AND OBJECTIVE: Medical image processing can contribute to the detection and diagnosis of human body anomalies, and it represents an important tool to assist in minimizing the degree of uncertainty of any diagnosis, while providing specialists with an additional source of diagnostic information. Strabismus is an anomaly that affects approximately 4% of the population. Strabismus modifies vision such that the eyes do not properly align, influencing binocular vision and depth perception...

PURPOSE: Consecutive exotropia may be associated with limited adduction, which has been reported to be caused by 1 or more anatomic abnormalities of rectus muscles or their insertions. We studied the relative frequency of grades of adduction deficit and the relative frequency of abnormal anatomic findings. DESIGN: Retrospective cohort study. PARTICIPANTS: Patients undergoing surgery for consecutive exotropia. METHODS: Preoperative duction deficits were graded on a -5 (severe limitation) to 0 (normal) scale...

PURPOSE: Few studies report the prevalence and types of strabismus, or average of stereopsis in Japanese adults. We performed ophthalmological evaluation including motility and stereopsis during medical examinations at cooperative companies. METHODS: We studies 1214 volunteers. The average age was 41.2 ± 12.6 (range 20-86) years. Examinations were carried out using their customary eyewear, evaluating alternate prism cover test (APCT), and Titmus stereo test (TST)...

Moebius syndrome is characterized by congenital facial palsy and limitation in horizontal gaze. The surgical results of the exotropic pattern are rare and have not been published before. The authors report three cases of exotropic Moebius syndrome. Maximal weakening of the lateral rectus muscles followed by strengthening of the medial recti in exotropic Moebius syndrome can improve exotropia significantly. Most of these cases also need some measures to relieve the often associated severe dry eye. [J Pediatr Ophthalmol Strabismus...

PURPOSE: Plication is a muscle-strengthening procedure in which a muscle is not dissected from its point of insertion. The purpose of this study was to compare the results of plication-recession (PR) with those of resection-recession (RR) in adult patients with intermittent exotropia (XT). METHODS: Patients with XT who underwent either PR or RR with a minimum postoperative follow-up of 12 months were retrospectively reviewed. Postoperative mean distance deviation and surgical outcomes were compared at 1 week and at 1, 3, 6, and 12 months, and at the final follow-up...

An 11-year-old girl presented to our tertiary eye care centre with a 9-month-old history of lime injury in the left eye in 1999 with vision of counting fingers close to the face. She initially underwent superficial keratectomy with amniotic membrane graft in 1999. Subsequently, cultivated limbal epithelial transplantation was performed in 2001 which improved her vision to 20/400. Following development of pannus and symblepharon in the left eye, she underwent pannus resection and conjunctival limbal autograft in 2002 and, a month later, optical penetrating keratoplasty (PK) following which her vision improved to 20/125...

AIMS: To investigate influence of test distance on stereoacuity in intermittent exotropia (X[T]) using the same test conditions for both near and far distances. METHODS: Subjects were 38 consecutive patients with X(T). All the patients were between ages 6 and 15 years and had decimal visual acuity of 1.0 or better. Another inclusion criterion was presence of phoric condition at near and far distances. Stereoacuity was measured at a near distance of 40 cm and at a far distance of 5 m...

BACKGROUND: In patients with moderate- to large-angle exotropic deviations, surgical correction remains the definitive treatment. The purpose of this study was to identify preoperative factors that correlate with surgical success and to produce a binomial model that predicts success based on preoperative factors. METHODS: We performed a retrospective review of patients with intermittent exotropia who underwent uniocular recession-resection surgery. Success was defined as ocular deviation ≤10(Δ) exotropia and ≤5(Δ) esotropia at distance at last follow-up (at least 3 months' postoperatively)...

BACKGROUND: Dorsal midbrain syndrome (also known as Parinaud syndrome and pretectal syndrome) is a well-known complication of tumors of the pineal region. However, there are few reports regarding outcomes, especially in children. The purpose of this study was to report the ophthalmic outcomes in a group of children with pineal tumors treated at a single institution. METHODS: The medical records of pediatric patients diagnosed with pineal region tumors and evaluated at our ophthalmology clinic were studied retrospectively...

Disruption of binocular vision during the critical period for development leads to eye misalignment in humans and in monkey models. We have previously suggested that disruption within a vergence circuit could be the neural basis for strabismus. Electrical stimulation in the rostral superior colliculus (rSC) leads to vergence eye movements in normal monkeys. Therefore, the purpose of this study was to investigate the effect of SC stimulation on eye misalignment in strabismic monkeys. Electrical stimulation was delivered to 51 sites in the intermediate and deep layers of the SC (400 Hz, 0...
