Purpose To understand the clinical presentation and possible mechanism of photophobia in neuro‐ophthalmological conditions. migraine and meningitis and lesions along the anterior visual pathway. Methods case studies, literature review Results Photophobia is a symptom that commonly accompanies migraine and meningitis. It occurs occasionally with lesions along the anterior visual pathway and in particular with suprasellar mass lesions, even if there is no evidence of chiasmal dysfunction. Such patients complain of a variety of symptoms related to excessive light perception. These take the form of photopsias, glare, dazzle, light aversion and photooculodynia. Conclusion Recent evidence and new physiologic concepts related to centrally‐mediated light sensitivity and intolerance point to the thalamus as an integrating center for light and nociceptive signals. We will review these "photophobia circuits" and examine their application in clinical neuroophthalmologyCommercial interest
