Abstract
This study evaluated the clinical characteristics and functional vision examination results in infantile cerebral palsy (CP) cases with cerebral visual impairment (CVI). Thirty-one infantile CP cases with CVI were retrospectively analyzed. Nystagmus, strabismus, hyperopia astigmatism, and optic atrophy were present in 6%, 74%, 51%, and 23% of cases, respectively. The mean fixation time was 3.87 ± 2.97 s. Object tracking was absent in 29% and poor in 19%. Difficulty in visual complexity, novelty, and latency were reported in 77%, 74%, and 68% of cases, respectively. CVI severity was classified as phase 1 in 55%, phase 2 in 29%, and phase 3 in 16%. In phases 1 and 2, 50% showed a color preference, and 54% had a visual field preference. Infantile CP cases with CVI often exhibit short fixation times and CVI-specific visual responses. Functional vision assessment is valuable for early diagnosis and visual rehabilitation support.
