Photophobia, or light sensitivity, is one of the common symptoms that is associated with visual snow. It is an intolerance of light. Headlights, sunlight, fluorescent bulbs, incandescent light, and camera flashes can all be very bothersome to the eye. You may need to squint or close your eyes to escape it, and are often left with a persistent after-image.
While photophobia is a symptom of visual snow and PMA it can also be caused by another underlying problem, such as a corneal abrasion, uveitis or a central nervous system disorder. It may also be caused by a retinal detachment, contact lens irritation, LASIK, albinism, total color deficiency, botulism, rabies, mercury poisoning, conjunctivitis, keratitis, iritis, keratosis follicularis spinulosa or decalvans (KFSD). Some medications may cause photophobia as a side effect, including belladonna, furosemide, quinine, tetracycline and doxycycline. |
