Which of the following is a common childhood visual impairment?

Cortical visual impairment is the most common reason children have vision problems, and it occurs when the brain's processing of visual information is disrupted rather than the eyes themselves being diseased. The eyes often look normal and have normal pupil reactions, but vision is affected because the issue lies in the visual pathways or cortex. This type of impairment is frequently seen in kids who have had perinatal brain injury, hypoxic events, or other neurologic insults, making it a leading cause of visual impairment even when the ocular exam is intact. Clinically, CVI shows up with variability in responses, difficulty with complex or cluttered visual scenes, and a tendency to rely on motion, light, or highly familiar stimuli, with performance influenced by arousal and environmental factors. The other options describe structural eye or retinal problems (such as retinal issues from prematurity or congenital eye malformations like very small eyes or absence of the eye), which involve the eye itself and are not as commonly the primary cause of childhood visual impairment as CVI.
