BACKGROUND: Normal visual development occurs when the brain is able to integrate the visual input from each of the two eyes to form a single three-dimensional image. The process of development of complete three-dimensional vision begins at birth and is almost complete by 24 months of age. The development of this binocular vision is hindered by any abnormality that prevents the brain from receiving a clear, similar image from each eye, due to decreased vision (e.g. amblyopia), or due to misalignment of the two eyes (strabismus or squint) in infancy and early childhood...

RANDOMIZED CONTROLLED TRIAL

BACKGROUND: Childhood intermittent exotropia [X(T)] is a type of strabismus (squint) in which one eye deviates outward at times, usually when the child is tired. It may progress to a permanent squint, loss of stereovision and/or amblyopia (reduced vision). Treatment options for X(T) include eye patches, glasses, surgery and active monitoring. There is no consensus regarding how this condition should be managed, and even when surgery is the preferred option clinicians disagree as to the optimal timing...

The Early vs. Late Strabismus Surgery Study Group is a group of strabismologists and orthoptists who wish to investigate whether early or late surgery is better in cases of infantile strabismus, in a controlled, multicentre, matched-pair trial: All infants will receive a standardized entry examination at age one and then be operated either before their second birthday in clinics A, or between the 32nd and 60th month of age in clinics B. The children will be evaluated at age six. After completion of the study, one child will be selected from each group, to form a pair of children with the same entry examination, who were operated early or late...

COMPARATIVE STUDY
I L Kulikova, N P Pashtaev, S V Suslikov
The effectiveness, safety, and stability of multimodality treatment for hyperopia, hyperopic and mixed astigmatism complicated by amblyopia and anisometropia were studied in 117 patients (117 eyes) aged 9 to 16 years, by using the new laser units "Lik-100" and "Glasser" at 1.54 microm. The patients were divided into 3 groups: 1) 43 patients (43 eyes) with hyperopia, spheric anisometropia and amblyopia; 2) 38 patients (38 eyes) with hyperopia, simple and complicated hyperopic astigmatism, astigmatic anisometropia, and amblyopia; 3) 36 patients (36 eyes) with hyperopia, simple and complicated hyperopic astigmatism, mixed anisometropia, and amblyopia...

PARTICIPANTS: Seventy-one consecutive patients with a clinical diagnosis of Crouzon syndrome assessed before craniofacial or ophthalmic surgery at the Australian Craniofacial Unit between 1984 and 2000. METHODS: Review of clinical records with documentation of patient age, gender, visual acuity, refractive error, diagnosis of amblyopia, squint, eye movement dysfunction, nystagmus, fundus examination, examination of the anterior segment, interpupillary distance, and intercanthal distance...

PURPOSE: This report presents two clinical interested cases. The main indication to intervene was diplopia, despite of macula damages and amblyopia. MATERIAL AND METHODS: We describe two clinical interested cases of divergent squint caused by sensory deprivation in course of permanent macula damage. Every patient was observed at least 5 years. We estimated decrease of diplopia and final eye alignment. RESULTS: Both patients did not complain of diplopia, we confirmed very good cosmetic effect and fixed angle of squint...

OBJECTIVE: To investigate the expression and distribution of N-methyl-D-aspartate receptor subunit 1 (NMDA-R1) in neuronal ultrastructure in visual cortex of strabismic amblyopic cat during development. METHODS: Eleven kittens were used for this study. Esotropia in six kittens had been made monocularly by tenotomy at two weeks of age. Two pairs of normal and strabismic kittens were sacrificed in three weeks of age, one week after tenotomy. Another two pairs of normal and strabismic kittens were sacrificed in five weeks of age, three weeks after tenotomy...

AIMS: To determine what systems are in place within ophthalmic services for the assessment and management of children suspected of having amblyopia and strabismus. To find out what methods are used for the assessment of these children. METHODS: A questionnaire-based study auditing 288 orthoptic departments in the UK. RESULTS: Responses were received from 75% orthoptic departments. Most hospitals employ more than one system for the assessment of strabismus and amblyopia, which is generally dependent on route of referral...

UNLABELLED: The aim of our study was to evaluate the results of the operation on squint with pathological attachment of lateral rectus revealed during surgery. MATERIAL AND METHODS: The study involved 22 children (12 girls and 10 boys) out of 320 children operated on for squint in the years 1993-1996, who had pathological attachment of lateral rectus. Alternating convergent squint was found in 12 children, unilateral in 10. Muscle exposure showed dislocation of lateral rectus attachment--upwards by c...

BACKGROUND: The Early vs Late Infantile Strabismus Surgery Study Group investigates whether early or late surgery is preferable in infantile convergent strabismus, in a non-randomised, prospective, multicentre clinical trial. The current state of the study after end of recruitment is reported here, focusing on the question of possible sources for bias in this non-randomised trial. METHOD: The prognostic factors were analysed at baseline in order to check for imbalances between the two treatment groups...

BACKGROUND: Williams-Beuren syndrome (WBS) is a developmental disorder of unknown etiology. The classical features include: 1) a supravalvular aortic stenosis, 2) "elfin" facies and 3) mental deficiency. Ocular findings can be irisabnormalities (stellate, pattern), tortuositas vasorum and, though not essential for diagnosis, strabismus is commonly found. Three cases of WBS with convergent squint which underwent surgical treatment are presented. Biopsy and histological studies were performed in two cases...

The results of squint surgery in 118 children with non-paralytic childhood esotropia are analysed. A 'favourable outcome', defined as a final alignment within +/- 10 dioptres of straight, or within +/- 20 dioptres of straight if there was evidence of binocular single vision, was achieved in 86 (72.9%) children. The factors affecting the final outcome are discussed, including age of onset, age at the time of surgery, pre-operative and post-operative amblyopia, refractive error, anisometropia, the surgical procedures used, and post-operative ocular alignment...

PURPOSE: To follow the development of strabismic amblyopia longitudinally by comparing mean amplitudes and the visual spatial resolving ability of retinal and cortical pattern responses at various stages of postnatal development in unilateral iatrogenic convergent strabismic kittens. METHODS: Surgery to produce iatrogenic convergent strabismus was performed on 20 kittens at 3 weeks of age; three kittens were used for controls. The monocular transient pattern electroretinogram (PERG) and pattern visual evoked potential (PVEP) were recorded simultaneously on the 23 kittens throughout development...

The results of squint surgery in 42 children with primary, non-paralytic, childhood exotropia are analysed. A 'favourable outcome', defined as a final alignment for near and distance within +/- 10 dioptres of straight, or within +/- 20 dioptres of straight with evidence of binocular single vision, was achieved in 39 (93%) children. The factors affecting the final outcome are discussed, including age of onset, age at the time of surgery, preoperative and post-operative amblyopia, refractive error, anisometropia, the surgical procedures used, and postoperative ocular alignment...

PURPOSE: To answer the question, whether it is possible to achieve a functional improvement after strabismus surgery in adults. METHODS: The study comprised 71 patients, aged 13-53, in whom after strabismus surgery, deviation was reduced to +/- 4 degrees. The degree of binocular vision was examined with weak and strong dissociating tests. RESULTS: Complete binocular vision was achieved in 25% of cases, partial with peripheral fusion in 51%...

Case report of a now 9-year-old boy with a pronounced persistent pupillary membrane in both eyes combined with amblyopia and eccentric fixation in the right eye and a convergent squint. After surgery removing the persistent pupillary membrane in both eyes at the age of 4 years, pleoptics and orthoptics were applied. Visual acuity and eccentric fixation did not improve. Strabismic surgery was carried out with good cosmetic result. Aetiologically, one can assume a deprivation by the persisting pupillary membrane...
