Photophobia, or intolerance of light, is not completely understood as a symptom. It has been divided into ocular and central types. This study shows that persistent, usually mild, photophobia occurs in about one-third of children with cortical visual impairment (CVI). When the CVI is congenital the photophobia is present from birth, and when it is acquired the sensitivity to light appears immediately after the brain insult. The intensity of photophobia tends to diminish with time and occasionally it may even disappear. The pathophysiology is unclear, as in all other neurological disorders associated with photophobia.
畏光，即对光线不耐受，作为一种症状尚未被完全理解。它已被分为眼部型和中枢型。本研究表明，持续性（通常为轻度）畏光发生在约三分之一的皮质视觉障碍（CVI）儿童中。当CVI为先天性时，畏光自出生就存在；当为后天获得性时，对光的敏感性在脑损伤后立即出现。畏光的强度往往会随着时间减弱，偶尔甚至可能消失。与所有其他伴有畏光的神经疾病一样，其病理生理学尚不清楚。
