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)...

BACKGROUND: Variable preoperative deviations and compensatory mechanisms may cause wrong dosage of strabismus surgery and result in over- or undercorrection. A long-lasting prism adaptation test (PAT) before surgery is supposed to reduce those difficulties and to improve the postoperative results. To date, the use of prism adaptation before surgery has not been systematically examined. METHODS: A total of 15 strabismologists and 28 orthoptists in Austria were interviewed about their approach to prism adaptation in 9 types of strabismus...

We report a case of an 11-year-old boy referred for evaluation of esotropia associated with a 4-year history of intermittent headaches and vomiting triggered by sudden movements, such as sneezing and coughing. Magnetic resonance imaging (MRI) performed 3 years previously was reported to be normal. A thorough clinical examination revealed the clinical features of Dorsal midbrain syndrome with Bruns syndrome and bilateral superior oblique palsy. Advanced MRI sequences revealed a freely mobile intraventricular cysticercus causing obstructive panhydrocephalus...

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...

A 46-year-old male patient was referred to our clinic with complaints of diplopia and esotropia in his right eye that developed after a car accident. The patient had right esotropia in primary position and abduction of the right eye was totally limited. Primary deviation was over 40 prism diopters at near and distance. The patient was diagnosed with sixth nerve palsy and 18 months after trauma, he underwent right medial rectus muscle recession. Ten months after the first operation, full-thickness tendon transposition of the superior and inferior rectus muscles (with Foster suture) was performed...

A 78-year-old woman complained of gradual, painless onset of horizontal binocular diplopia associated with progressive axial weakness. Physical examination revealed esotropia that was greater at distance than at near vision, bilateral levator dehiscence, and normal abducting saccadic speeds. Given the age of the patient and compatible clinical findings, the diagnosis of Sagging Eye Syndrome (SES) was made. However, further work-up with a muscle biopsy suggested Sporadic Late-Onset Nemaline Myopathy (SLONM) as the cause of her progressive muscle weakness...

Oculomotor abnormalities are rarely noted in thalamic strokes. We describe isolated right pseudoabducens palsy in a young patient with acute left thalamic infarction revealed by diffusion-weighted magnetic resonance imaging. The patient's horizontal diplopia and oculomotor palsy resolved within 3days. This case supports the hypothesis that a lesion can cause isolated esotropia by interrupting descending inhibitory convergence pathways that traverse the paramedian thalamus and decussate in the subthalamic region to innervate the contralateral third oculomotor nucleus...

PURPOSE: To study prospectively the effect of extirpating the proprioceptive impulse at the myotendinous junction combined with recession of the medial rectus muscles in patients with convergence excess esotropia. METHODS: A total of 21 patients with different sizes of AC/A ratios (high, 8; normal, 12; low, 1) underwent a surgical procedure consisting of combining resection of 2.5 mm of the insertional end of the medial rectus muscles with recession from the original insertion, based on the patient's angle of esotropia at 1/3 m while wearing full cycloplegic refraction, with an additional recession of 1 mm for each rectus muscle based on current surgical tables...

Many different surgical approaches have been advocated for the treatment of esotropia with a high ratio of accommodative convergence to accommodation, most involving increasing the magnitude of medial rectus recessions over than the amount recommended for the distance esotropia to either partially or fully correct the larger near esotropia. Maximal medial rectus recessions are relatively successful in correcting the excess near esotropia without overcorrecting the distance esotropia, but the expected loss of excess convergence over time raises the possibility of late overcorrections...

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)...

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 (400Hz, 0...

AIM: To evaluate long term follow-up (10y) of 6 muscle surgical approach in essential infantile esotropia (EIE). METHODS: A 6 muscle approach to EIE was retrospectively evaluated in patients with inferior oblique (IO) hyperfunction and lateral rectus (LR) pseudoparalysis, who underwent surgery at different ages. Different clinical characters were analyzed pre- and postoperatively, in patients who underwent a 6 muscles approach ≤4 years of age. All patients underwent a multiple muscles approach: bilateral medial recti (MR) recession (4-5 mm), bilateral LR resection (lower than 7 mm) and bilateral IO recession and anteroposition...

To evaluate clinical factors associated with the onset of consecutive exotropia (XT) following esotropia surgery.By a retrospective nested case-control design, we reviewed the medical records of 193 patients who had undergone initial esotropia surgery between 2008 and 2015, and had follow-up longer than 6 months. The probable risk factors were evaluated between groups 1 (consecutive XT) and 2 (non-consecutive exotropia). Pearson chi-square test and Mann-Whitney U test were used for univariate analysis, and conditional logistic regression model was applied for exploring the potential risk factors of consecutive XT...
