What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to test a home treatment for individuals with amblyopia, commonly known as "lazy eye." Participants will use the CureSight device to improve vision by wearing it for 1.5 hours a day, six days a week, over three to six months. The trial seeks individuals with amblyopia who do not fit the usual categories of previous studies. It is not suitable for those without home WiFi or with conditions that prevent vision improvement. As an unphased trial, this study offers a unique opportunity to explore innovative treatment options for amblyopia in the comfort of one's home.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that the CureSight device is safe for treating amblyopia?

Research has shown that the CureSight treatment for amblyopia, or "lazy eye," is safe for patients. Earlier studies found no serious side effects. Any minor side effects were temporary and resolved on their own. The FDA has approved this treatment for children aged 4 to under 9 years, indicating it has been carefully tested for safety in that age group. Although this trial includes older participants, existing research provides a good indication of its safety. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Unlike the standard treatments for lazy eye, which often involve patching the stronger eye or using atropine drops to blur it, SureSight offers a novel approach by using a digital therapeutic method. This innovative treatment works through a specialized device that provides visual stimuli to improve the weaker eye. Researchers are excited because SureSight has the potential to be a non-invasive, user-friendly alternative that could enhance compliance and effectiveness, especially for those who fall outside the typical FDA treatment ranges for amblyopia.

What evidence suggests that the CureSight device is effective for treating amblyopia?

Research has shown that the CureSight system, which participants in this trial will use, effectively treats amblyopia, also known as lazy eye. Studies have found that patients using CureSight improved their vision sharpness significantly more than those using only glasses. Specifically, patients experienced an improvement of 1.8 logMAR with CureSight, compared to just 0.8 logMAR with glasses alone. Additionally, 93% of parents reported satisfaction with the treatment results. The CureSight device employs a new method with eye-tracking technology to help train the eyes, making it a promising option for those who may not benefit from traditional treatments. ^{1 4 6 7 8}

Amblyopia, or 'lazy eye,' affects about 2-3% of the population and is most effectively treated during infancy or early childhood.

The primary treatment involves patching the stronger eye to force the weaker eye to develop better vision, as simply addressing the underlying cause is not sufficient for improvement.

A new treatment method for children with accommodation cramp and progressive myopia involves alternating their focus between a close TV screen and a far one, which has shown promising results.

In a study of 65 children, this method improved their relative accommodation and significantly reduced the progression of myopia to only 0.045 diopters over a year, compared to 0.5 diopters in the control group.

Traditionally, patching the good eye has been the primary treatment for amblyopia (lazy eye) for over a century.

Recent research indicates that spending time in complete darkness may lead to a rapid improvement in vision for individuals with amblyopia, suggesting a new potential treatment approach.

In a study of 99 patients who underwent surgery for esotropia, 70.7% achieved excellent outcomes shortly after surgery, although this number decreased to 57.6% at the final follow-up, indicating that while initial results are promising, long-term success may vary.

Risk factors for poorer surgical outcomes included simultaneous vertical muscle surgery and superior oblique muscle palsy, highlighting the importance of considering these factors during preoperative counseling.

Office-based vergence/accommodative therapy significantly improved accommodative amplitude by an average of 8.6 diopters in children with convergence insufficiency, compared to a 5.2 diopter improvement in the placebo group, indicating a meaningful therapeutic effect.

The therapy also enhanced accommodative facility, with an average increase of 13.5 cycles per minute in the treatment group versus 7.6 in the placebo group, and a higher percentage of participants achieving normal function (85% vs. 49%), demonstrating its efficacy in addressing these visual dysfunctions.

A randomized clinical trial involving 75 children aged 4 to 8 years with amblyopia is testing the effectiveness of a novel treatment called I-BiT™, which uses 3D technology and computer games, compared to traditional methods.

The trial will assess changes in visual acuity over 6 weeks of treatment, aiming to improve compliance and outcomes in amblyopia treatment, which traditionally suffers from low adherence to patching therapy.

In a study of 216 Honduran children, both the SureSight autorefractor and the plusoptiX A09 photoscreener were effective in detecting amblyopia risk factors, with the plusoptiX showing higher specificity (80%) compared to SureSight (71%).

Both screening devices demonstrated high sensitivity (89%) for identifying amblyopia risk factors, making them reliable options for vision screening in rural settings.

The Welch Allyn SureSight vision screening tool was used effectively on over 15,000 preschool children, achieving reliable results in more than 99% of cases, indicating its high efficacy for large-scale screenings.

Adjusting referral criteria improved the positive predictive value (PPV) of the screenings, reaching about 64% at a 4% referral rate, but further adjustments did not enhance PPV and risked reducing sensitivity, highlighting a balance needed in screening practices.

Patient compliance with amblyopia treatments, such as eye patching and atropine drops, is often lower than prescribed, which negatively impacts visual acuity outcomes.

The implementation of the Inside Out Care online platform has successfully improved monitoring of patient compliance with amblyopia therapies and enhanced communication between doctors and patients.

The novel binocular eye-tracking treatment, CureSight, demonstrated noninferior visual acuity improvement compared to traditional patching in children with amblyopia, with both groups showing significant gains in visual function after 16 weeks of treatment.

CureSight treatment had higher adherence rates (91%) compared to patching (83%), suggesting it may be a more acceptable alternative for young children undergoing amblyopia treatment, with no serious adverse events reported.
