INTRODUCTION With a prevalence of 3-5%, amblyopia represents a major public health problem. Effective treatment depends on early detection, and a broad consensus of professional opinion supports vision screening of infants and young children. No single method of screening has been demonstrated to be superior in detecting amblyopia and all methods have significant limitations. METHODS We asses...

215 preschool siblings of children presenting with squint/amblyopia were screened by refraction after cycloplegia. The presence of +2.00 or more D of spherical hypermetropia in both eyes, or +1.00 or more D sphere or cylinder of anisometropia was significantly associated (P=0.0779%) with that child being identified 2+ years later as having either squint or amblyopia or both. Astigmatism of +1.5...

BACKGROUND RAMSES is a 7 year follow up study, aiming at the evaluation of the effectiveness and the efficiency of screening for amblyopia. In this first report, concerning the first 2 years of life, the compliance with the prevention programme and the positive predictive value (PPV) of the screening tests used, are presented. METHODS All results of the standardised screening test for strabis...

+2-00 to +2-75 dioptres of spherical hypermetropia in the more emmetropic of a pair of eyes is significantly associated with esotropia (P less than 0-001) and the presence of amblyopia (P less than 0-01). Anisometropia is not significantly associated with esotropia (P = 0-31) unless there is spherical hypermetropia of +2-00 dioptres or more in the more emmetropic eye (P less than 0-001). Hyperm...

STUDY OBJECTIVE To investigate the relationship between age at presentation of amblyopia and social deprivation before and after the introduction of changes to a vision screening service. DESIGN Two cohorts of children treated for amblyopia in 1983 and 1992. SETTING THe orthoptic department of Leicester Royal Infirmary. PARTICIPANTS The 209 patients treated for amblyopia who first attende...

Eighty consecutive patients with amblyopia ex anopsia were treated with the Cambridge Stimulator (Cam.). Each patient received an average of six, 15 minute treatment sessions at a frequency of 7-2 per week. Treatment was terminated after two consecutive treatments indicated no change in visual acuity. Sixty-nine patients were given mmimal occlusion simultaneously with Cam. treatment. Eleven pat...

Aim This study measured the prevalence of amblyopia in preschool and school children between 4 and 15 years of age in Tuzla, Bosnia and Herzegovina and as well and to examine its relations with anisometropia and strabismus. Methods Children from eight daycare centers and twenty four elementary schools were screened for amblyopia by volunteer personnel (medical students), any child who failed ...

The treatment of amblyopia is centuries old. A systematic description of occlusion therapy was provided by Leclerc' in 1743, and to this day the method has by and large remained unchanged. Although occlusion often leads to beneficial results,23 there are cases where it is unacceptable to the child and frustrating for the parents. When occlusion has failed other methods have been tried." Dazzlin...

Recent studies have shown that perceptual learning has the potential to treat amblyopia. In this study we tested whether a recent perceptual learning technique that improved visual functions in adults can be applied to improve the vision of children after the conventional treatment of patching has failed. A prospective clinical pilot study was carried out in children who were non-compliant with...

INTRODUCTION OR BACKGROUND With a prevalence of 2-5%, amblyopia is the most common vision deficit in children in the UK and the second most common cause of functional low vision in children in low-income countries. SOURCES OF DATA Pubmed, Cochrane library and clinical trial registries (clinicaltrials.gov, ISRCTN, UKCRN portfolio database). AREAS OF AGREEMENT Screening and treatment at the a...
