The early visual screening of children plays a critical role in promoting visual development, especially for those with visual impairments. Among various approaches, eye-tracking based visual assessment has emerged as a promising tool, particularly for infants, toddlers, and children with developmental disabilities who are unable to complete traditional vision tests. The object of this study is to design and investigate the effectiveness of using a deep learning based, individualized eye-tracking system to assess visual function, specifically visual acuity and visual field, in typical preschool children and infants under the age of three. This study aims to establish a reliable, noninvasive visual screening method that accommodates the diverse needs and abilities of young children.
NCT06585657
The goal of this clinical trial is to investigate whether brain visual perception training can effectively prevent myopia in children with pre myopia. It will also learn about the safety of brain visual perception training. The main questions it aims to answer are: Does brain visual perception training slow down the growth of axial length? What medical issues may participants encounter when using the brain visual perception training system? Researchers will compare participants who receive brain visual perception training with a control group to see if the training group can delay the onset of pre myopia in children Participants will: The training group will receive 20 minutes of brain visual perception training once a day for a period of one year. Follow up check ups at the hospital every 3 months. Keep a diary of the values of axial length and refractive diopter.
NCT06122519
This study mainly investigated the incidence of eye diseases in children with autism spectrum disorder(ASD) in Tianjin area, and analyzed related risk factors, so as to raise attention to eye diseases in children with ASD. To evaluate the impact of ophthalmic treatment on the quality of life of children with autism and their primary caregivers.
NCT05468775
The study used children aged 6-18 as subjects to evaluate the efficacy and safety of naked eye 3D vision training for the prevention and control of myopia in adolescents. A total of 250 subjects were recruited from Zhongshan Ophthalmology Center of Sun Yat-sen University, Shenzhen People's Hospital and Foshan Women's and Children's Hospital, with 1:1 as intervention group and control group. The study assumes that daily naked eye 3D vision training can effectively control the speed of axial elongation and the progression of myopia. The main indicators were the use of optical biometrics to detect the subjects' initial axial length and the axial length after 1 month, 3 months and 6 months of intervention. Secondary indicators were refraction, uncorrected visual acuity, best corrected visual acuity, choroidal thickness, and binocular vision.

EyeSwift Pro assessment of visual function parameters as measured by psychophysics
NCT02821403
Working Hypothesis: The blue-light blocking lens has no effect on the contrast sensitivity, accommodative response, color vision, and subjective grading of the quality of life and vision. Purpose: To determine and compare the visual performances after wearing the blue-light blocking lenses in participants with and without presbyopia. Methods: One hundred and sixty computer users (computer usage \>2 hours/day) with (n=120, aged \>40years) and without presbyopia (n=40, aged 18-35 years) will be recruited. Three pairs of ophthalmic lenses will be prescribed for the participants, in which one pair of them will be the blue-light blocking lenses (StressFree, Swisscoat, HK). The lenses will be used for intermediate vision (i.e., computer usage) in presbyopic group, and for distant vision in non-presbyopic group. The adaptation period for each pair of lenses will be 1 month. The pre- and post-treatment contrast sensitivity, accommodative response and color vision will be measured. The participants will also be asked to complete questionnaires about their quality of life and vision, and the performances of these ophthalmic lenses. Significance: The blue-light blocking lens reflects the short-wavelength lights and protects the retina from "blue-light hazards"; however, blue lights are essential for various visual function and circadian rhythms. This study will evaluate the impact of the blue-light blocking lenses on visual function and quality of life, and determine whether the blue-light blocking lenses are good choices for extra ocular protection.

It is the purpose of this study to attempt to determine if there is an immediate, measurable change in visual function as a direct result following a session of cranial osteopathic manipulation.
