Encyclopedia

From Wikipedia, the free encyclopedia

Photopsia is the presence of perceived flashes of light. It is most commonly associated with posterior vitreous detachment, migraine with aura, migraine aura without headache, retinal break or detachment, occipital lobe infarction and sensory deprivation (so called ophthalmopathic hallucinations). This condition has also been identified as a common initial symptom of Punctate Inner Choroiditis (PIC). PIC is a rare retinal autoimmune disease, believed to be caused by the immune system mistakenly attacking and destroying the retina.
