Validation of a Questionnaire Assessing Quality of Life in Children With Amblyopia and Strabismus

ASTEQ
Start date: n/a
Phase: N/A

Phase: N/A
Study type: Interventional

A single-arm, multi-center, open-label pilot study to evaluate the feasibility, safety, and efficacy of the Luminopia One digital therapeutic in improving visual acuity in a pediatric amblyopia population.

NCT ID: NCT02686879 Completed - Amblyopia Clinical Trials

Effect of Peripheral Defocus on Axial Growth in Hyperopes

Start date: June 2016
Phase: N/A
Study type: Interventional

Hyperopia, also known as farsightedness, is a common type of refractive error where distant objects may be seen more clearly than objects that are near. Hyperopia is a known risk factor for amblyopia, (lazy eye), which may occur as a result of a squint (turn), or due to different levels of hyperopia between each eye (anisohyperopia). Hyperopia and anisohyperopia often persist into adulthood resulting in impairment to binocular vision. Current management involves prescribing spectacles or contact lenses to correct the hyperopia in each eye, usually as a lifelong intervention. In recent years there has been a great deal of interest in delaying progression of myopia (short-sightedness) by slowing down the growth of the eye using a particular type of contact lens termed a centre-distance multifocal design. There have been some encouraging results in this area to date. The proposed study here would explore the use of centre-near multifocal design contact lenses to encourage growth of the eye, thereby reducing hyperopia. There are three elements to the programme of research: 1. The natural progression of axial growth and refractive error will be measured in hyperopic and anisohyperopic subjects aged between 5 and 19. In other words, the natural growth of the eye will be followed without any intervention 2. As a paired eye control study anisohyperopes aged between 8 and 15 will be fitted with a centre-near multifocal design contact lens in their more hyperopic eye and a single vision contact lens in the fellow eye, if required. The progression of axial growth and refractive error will be measured and compared in each eye 3. Subjects' aged between 8 and 15 with similar levels of hyperopia in each eye will be fitted with centre-near multifocal design contact lenses in each eye. The progression of axial growth and refractive error will be measured and compared to subjects in the natural progression study

NCT ID: NCT02536963 Completed - Amblyopia Clinical Trials

Improving Quality Vision Outcomes in Managed Care Setting While Reducing Cost by Use of Accurate, Automated Screening

Start date: January 2016
Phase:
Study type: Observational

Amblyopia ("lazy eye") and strabismus (misaligned eyes) are medical eye conditions that combine as the leading causes of preventable vision loss in children. They are irreversible if not detected and corrected by the age of seven, however half of all cases are missed because the conditions do not always manifest themselves and pediatricians are unable to reliably detect the conditions. The current health care system badly needs an accurate and effective approach toward detecting amblyopia and strabismus in preschool children. The study will be conducted in busy, ethnically and racially diverse primary care sites operated by the Kaiser Permanente system and compare the outcomes of testing with a Pediatric Vision Scanner with outcomes the current standard of care.

NCT ID: NCT02458846 Completed - Amblyopia Clinical Trials

Efficacy of Visual Screening in Ontario

Start date: September 2014
Phase: N/A
Study type: Interventional

Amblyopia (lazy eye), is the leading treatable cause of vision loss in childhood. Uncorrected refractive errors (ie farsightedness) can lead to difficulties in school. Unfortunately, many children do not receive vision screening until they have already developed irreversible vision problems. We will conduct a cluster randomized clinical trial in which schools, not individual children, are randomly allocated to receive a kindergarten visual screening program or to receive no intervention by the research team (i.e., "care as usual"). We will compare the prevalence of visual problems (and proportion of children with reading problems) when the children are in Grade 2, after allowing for at least one year of treatment.

NCT ID: NCT02200211 Completed - Amblyopia Clinical Trials

Study of Binocular Computer Activities for Treatment of Amblyopia

ATS18
Start date: September 11, 2014
Phase: N/A
Study type: Interventional

The purpose of the study is to compare the effectiveness of 1 hour/day of binocular game play 7 days per week with 2 hours/day patching 7 days per week in children 5 to <17

NCT ID: NCT02003235 Completed - Amblyopia Clinical Trials

Assessment of Device for Treatment of Amblyopia

Start date: October 2013
Phase: N/A
Study type: Interventional

The study will evaluate the effect of Reviview™, a dichoptic video display device for administrating a novel treatment protocol for Amblyopia (lazy eye) in kids. The effect of the treatment will be measured by the change from baseline in Visual acuity and in Stereoscopic Vision; and to assess the ease of use of and compliance by the patients.

NCT ID: NCT01832883 Completed - Amblyopia Clinical Trials

Amblyopia and Strabismus Detection Using a Pediatric Vision Scanner

Start date: December 2010
Phase:
Study type: Observational

The purpose of this project is to compare the performance of the Pediatric Vision Scanner (PVS) with the Gold Standard Examination to determine the effectiveness of the PVS at detecting amblyopia and strabismus.

NCT ID: NCT01791946 Completed - Amblyopia Clinical Trials

Binocular Treatment of Amblyopia Before and After Strabismus Surgery

Start date: January 2013
Phase: N/A
Study type: Interventional

The primary objective of this study is to assess the effectiveness of an investigational binocular treatment in improving vision in strabismic amblyopes (i.e., patients with lazy eye, or poor vision in one eye due to a present or former eye misalignment). Patients will be randomized to receive the study treatment either before or after strabismus surgery (i.e., corrective eye alignment surgery) or sham treatment before surgery. The study hypothesis is that there will be no significant change in vision in neither the pre nor post-surgery groups and no significant change in vision in neither the sham nor actual treatment groups.
