Strabismus

This study compares two treatments for a type of crossed eye (small-angle esotropia) that started recently. One group will do special eye exercises, and the other will wear prism glasses. The goal is to see which approach better straightens the eyes and improves 3D vision. About …

This trial compares two surgical procedures for treating large-angle exotropia, a condition where the eye turns outward. One technique is true muscle transplantation surgery, and the other is augmented semi hang back recession. The study will enroll 40 patients with exotropia gre…

This trial tests a 12-week home-based eye training program for children and young adults aged 6 to 25 with intermittent exotropia, a condition where one eye periodically turns outward. The training uses a computer or tablet game with 3D glasses to strengthen near vision control, …

This study tests whether watching custom dichoptic videos for 8 weeks can improve eye alignment control in children with intermittent exotropia (a type of eye misalignment). Forty children will be assigned to watch either dichoptic or standard videos. The goal is to see if this n…

This study tests two surgical methods to correct large-angle exotropia (a type of crossed eyes) using only one eye. One method moves a piece of muscle to the side, the other splits the muscle in a Y-shape. Researchers will measure how straight the eyes become and check for any si…

This study tests whether a nasal spray of dexmedetomidine can reduce agitation in children aged 3-6 after strabismus (eye muscle) surgery. 120 children will receive either 2 or 3 micrograms per kilogram of the medicine. The goal is to find the best dose to help children wake up c…

This study tests whether doing eye exercises in virtual reality can help people with certain eye nerve palsies move their eyes more. The VR scene moves with the person's head while they do visual tasks. The goal is to see if this improves eye movement range. The study involves 40…

This study is testing whether playing video games and doing special vision exercises can improve eyesight in both children and adults with amblyopia (lazy eye). Researchers will measure changes in visual acuity, depth perception, and contrast sensitivity before and after the trai…

This study looks at a new way to provide eye care to children in rural China. It will involve about 20,000 kids aged 3 to 18 from schools in several counties. The goal is to see if a coordinated program across local health centers and schools can improve eye screening rates and h…

This study looks at how well people with amblyopia (lazy eye) or strabismus (crossed eyes) see before, during, and after common treatments like patching, glasses, or surgery. Researchers will measure things like sharpness, contrast, and reading ability. The goal is to better unde…

This study looks at eye problems in people with craniosynostosis, a condition where skull bones close too early. Researchers will check for issues like crossed eyes, lazy eye, and pressure inside the head. The goal is to better understand these eye problems to help improve care.

This study aims to find genes that cause eye misalignment (strabismus) and related conditions involving the cranial nerves and brainstem. Researchers will analyze DNA from up to 20,000 participants with these disorders. The goal is to better understand the genetic causes, which c…

This study aims to find genetic variants linked to strabismus (crossed eyes) and nystagmus (involuntary eye movements). Researchers will analyze DNA from families with at least three members who have strabismus, or families with infantile esotropia or nystagmus. By comparing affe…

This study tests a special microscope that takes live 3D images inside the eye during surgery. It aims to help surgeons see better when treating conditions like retinal detachment, macular holes, and cataracts. About 262 people will take part, including healthy volunteers and sur…
