PURPOSE: The optimal management of infantile nystagmus syndrome (INS) is still unclear. Contact lenses (CL) may be superior to glasses in improving visual function in INS but it is not known whether their beneficial effects are due to optical correction alone, or to an additional proprioceptive effect, and whether soft CLs would be as effective as rigid CLs. There is little data on feasibility and and the present study aimed to provide this information. METHODS: We completed a pilot Randomized Control Trial (RCT) at a single tertiary referral centre in London, UK...

PURPOSE: To compare ocular deviation in the operating room depending on whether the patient is in supine decubitus or seated after single-stage adjustable strabismus surgery under topical anesthesia. MATERIAL AND METHOD: We performed a prospective observational study of 30 patients with horizontal and/or vertical strabismus who underwent single stage adjustable strabismus surgery under topical anesthesia. Both distance and near deviation were evaluated before surgery, during surgery in both positions (seated and supine), and at 1 day, 1 month, and 3 months after surgery...

BACKGROUND/AIMS: Strabismus due to sagging eye syndrome (SES) caused by age-related connective tissue involution is now an established cause of diplopia in older people. High suspicion of the condition results in early recognition, often obviating extensive neurological investigations and enabling surgical correction of the strabismus. METHODS: This retrospective study reviewed surgical results in 93 patients (40 males) of average age 68 ± 12 years, who had small-angle strabismus due to SES, during the 20-year period 1994-2014...

PURPOSE: Besides chiasmal hemidecussation, interhemispheric connections are likely important in human binocularity. The corpus callosum (CC) is the major fiber bundle in the mammalian brain which mostly connects homologous cortical areas in the two hemispheres. Visual interhemispheric connections were found abnormal in strabismic cats. No studies have investigated these pathways in humans with infantile strabismus. METHODS: Diffusion tensor imaging was used in four subjects with infantile esotropia (IE) and nine control subjects with normal binocularity, in order to study interhemispheric fibers in the CC connecting the right and left primary visual cortical areas...

INTRODUCTION: A spherical globe is traditionally assumed, but this study employed magnetic resonance imaging (MRI) to demonstrate frequent occurrence of non-spherical staphylomata in strabismic patients. METHODS: High-resolution, surface coil MRI was obtained in multiple image planes in 21 highly myopic subjects (36 eyes) and compared with 17 normal controls (33 eyes). Images were analyzed for axial length, aspect ratio of eye shape, and deflection of muscle paths...

The use of a conjunctival retractor that expands a small incision in the conjunctiva/Tenon's capsule facilitated the performance of strabismus surgery through a fornix incision. A wide field of exposure revealed the entire area of the muscle insertion. While there is a risk of conjunctival tearing in elderly patients, the use of the retractor is valuable.

PURPOSE: The aim of this study was to investigate the effects of induced vertical disparity on horizontal fusional reserves at near. MATERIALS AND METHODS: In 170 healthy subjects wearing best corrective refraction, the negative and positive horizontal fusional reserves were measured with base-in (BI) and base-out (BO) prisms, respectively, in the presence of 0.5 prism diopters (∆) and 1∆ vertical prisms placed in trial frames in front of the right eye. The prism power was slowly increased step by step until the subject reported sustained blur, break, and recovery...

BACKGROUND: In the Netherlands, youth-healthcare (YHC) physicians screen children 7 times for vision disorders between the ages of 1 and 60 months. Examination consists of inspection of the external structures of the eye, fundus red reflex, Hirschberg test, pupillary reflexes, cover-uncover test, alternating-cover test, eye motility, monocular pursuit, and, from 36 months onwards, visual acuity (VA). We observed how well these tests are done. METHODS: Screening test performance was assessed with semistructured observations...

PURPOSE: To determine the prevalence of amblyopia and its determinants in a population-based study in Mashhad County, Iran. METHODS: This cross-sectional, population-based study was conducted on the population of Mashhad County aged >1 year using randomized stratified cluster sampling. Examinations were performed after selection of the participants and their free transportation to the sampling site. The examinations included the measurement of uncorrected and corrected visual acuity, cycloplegic and non-cycloplegic refraction, cover testing, slit-lamp biomicroscopy, and ophthalmoscopy...

There is little published evidence relating to the final visual acuity of children who are identified as having reduced vision at a school screening program. The school vision screening program in Leeds (led by an orthoptist but delivered by health care support workers within the school nursing team) is examined. RESULTS: 7807 children were screened in school between November 1, 2013, and September 1, 2014. Of these, 319 (4%) failed the screen and were referred to the general optometry service and 547 (7%) were referred to the Children's Community Eye Service (CCES)...

Chikungunya fever is a disease caused by a virus from the same family as dengue and Zika. It is endemic in several parts of the world and has recently spread to Latin America. We report the case of a patient, aged 58 years, from Rio de Janeiro, Brazil, who in 2013 developed an acute bilateral third cranial nerve palsy sparing the pupil. After extensive investigation, it was diagnosed as caused by chikungunya infection. The patient was treated with pulse therapy and after 5 months of the onset of the condition, the patient showed improvement...

Anomalous orbital structures are suspected in restrictive strabismus with features of severe globe retractions, overshoots, or synergistic movements. We report a case of suspected Duane syndrome that was found to have an anomalous band beneath the lateral rectus muscle. Such abnormal structures are rare, but it is important to identify and manage them to optimize outcomes.

A case of an autistic child, aged 8 years, who reported binocular diplopia following just 2 hours total occlusion per day for 6 weeks for strabismic/anisometropic amblyopia is reported. There was a history of known long-standing reduced uniocular acuity without treatment. Pretreatment Sbisa bar assessment suggested moderate suppression. The diplopia was treated over 6 months including occluding the amblyopic eye and gradually reducing the density of the occluder until fixation with the nonamblyopic eye could be maintained and diplopia ignored...

PURPOSE: The 15∆ base in prism test (15∆BIPT) introduced by Gobin is often used in The Netherlands to detect fixation preference, especially in young and preverbal children in whom a reliable measurement of the visual acuity (VA) is difficult. It is assumed that the fixation preference detected by the 15∆BIPT can be used to predict the presence of amblyopia. The aim of this retrospective case note review was to investigate the accuracy of the 15∆BIPT in detection of amblyopia in anisometropic patients...
