Rapid visual development in infants is concentrated in the first few months of life; therefore, special attention should be given to visual function during this period, and it is important to intervene early if abnormalities in visual function are detected. When a baby is found to be unable to gaze at or track faces, or to respond only to bright light stimuli, a thorough ophthalmologic examination and visual testing should be performed. If it is determined that there are no abnormalities in the fundus opticus and that the problem may be a disorder in the higher visual pathways, rehabilitation intervention should begin immediately. To enable maximum visual development, in our experience, the earlier the intervention, the better the results. Visual stimulation methods are as follows: 1. Light reflex stimulation In a dark room, with the child lying on his back, use a flashlight to irradiate the child’s left eye, right eye, below the right eye, below the left eye (or right first, then left), under the eye is to have a gap time, each point of irradiation time to maintain 1 second, 5 times in a row as a group, 20-30 groups / day (in the child to find the light source, chasing the red light does not respond and weak response 2. Red light stimulation In a dark room, with the child lying on his back, place a flashlight wrapped in red cloth about 20 cm above the child’s eyes, that is, irradiate the child’s eyes with red light to attract the child’s attention to the red light, and then move the flashlight horizontally to allow the child to look after it. Repeat for 1 minute each time, 10-20 times/day. (This method is used when the child’s response to finding a light source is weak and does not respond to red light chasing) 3. black and white pictures, toys stimulation In a well-lit room, the child lies on his back, with black and white pictures, red balls, toys, etc. placed 20 cm above the child’s eyes, you can slightly adjust the picture distance, so that the child look at the picture, and then move the picture horizontally, so that the child chasing. The size of the pictures and toys can be adjusted according to the child’s gaze and chasing. (This method is used when the child can find the light source and chase the red light but has poor gaze and chasing of pictures and toys). 4. Bio-visual stimulation: 1) Look at the speaker’s face, the tester makes a soft and beautiful voice and exaggerates the smile to attract the child’s attention. The child is prompted to look at the face for a longer period of time through eye contact and voice communication, repeated for 1 minute each time, 10-20 times/day. 2) Follow the face of the speaker, make a beautiful sound to attract the child’s attention, and move the speaker’s face while attracting the child’s eyes to follow the face to improve the child’s perception of visual multi-directional stimulation, repeat for 1 minute each time, 10-20 times/day. Important note! The specific operation should be carried out by a professional rehabilitation staff for an appropriate time of visual stimulation every day, so that the quality can be guaranteed. Parents should be instructed to do it repeatedly during their baby’s waking hours. Active parental efforts in visual stimulation play a decisive role in restoring vision because parents have the longest contact time with their baby and can use any waking hours of their baby to do visual stimulation, which can maximize the effect of visual recovery.
