A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to enhance visual function in children with low vision through restorative visual rehabilitation techniques. It focuses on two primary objectives: first, to assess the impact of flickering black-and-white checkerboard patterns on visual development in children with mild to moderate low vision, and second, to create a tailored visual stimulation program for children with severe disabilities and visual impairments. The study will involve 200 children with various visual disorders and will utilize eye-tracking technology to validate new assessment methods. Interventions will include passive visual stimulation delivered through engaging visual materials to support visual learning.

Why it matters

Who can join: the full rules

Passive visual stimulation group

Inclusion Criteria:

1. Children aged less than or equal to 18 years old.
2. The causes of visual disorder in children are unlimited.
3. The acuity of the children's better eye was ≤ 0.2.
4. Children with multiple disabilities and visual disorders typically exhibit developmental levels ranging from moderate to severe or below.
5. The parents of these children exhibit a positive attitude and are willing to cooperate with visual learning programs.
6. Infants under 1 year old with low vision without other developmental issues , under or equal to moderate developmental issues.

Exclusion Criteria:

1. Significant refractive errors that affect acuity but are unable to cooperate with wearing corrective glasses in two training sessions.
2. Requires patching for monocular vision rehabilitation but is unable to cooperate with patching in two training sessions.
3. The individual is unable to adapt to the training environment and cooperate with visual learning in two sessions due to unstable emotions or difficulty adapting to the environment.

Perceptual learning group Inclusion Criteria

(1)Children aged less than or equal to 12 years old. (2)No restrictions on the causes of visual impairment in children. (3)The acuity of the children's better eye was ≤ 0.5 (4)If children have additional developmental issues, their disability severity should primarily be mild or moderate.

(5)The primary caregiver demonstrates a positive attitude and is willing to cooperate with the visual training program.

(6)The child is capable of completing calibration with an eye-tracking device. Exclusion Criteria

1. Significant refractive errors that severely affect vision, where the child cannot adapt to wearing corrective glasses within two training sessions.
2. Requires occlusion therapy for monocular visual rehabilitation but cannot cooperate with occlusion within two training sessions.
3. Inability to adapt to the training environment or cooperate with visual training due to emotional instability or difficulty adjusting within two training sessions.
4. Unstable physiological conditions (e.g., epilepsy, sleep disturbances) that prevent consistent participation in visual training.
