Sensorineural hearing loss is caused by damage to the cochlea in the inner ear or damage to the nerve pathways from the inner ear to the brain. Sensorineural hearing loss is the most common type of permanent hearing loss.
We donât really know why migraines cause light sensitivity, but itâs clear nearly everyone with migraine will tell you that they have sensitivity to light during an attack and many patients with migraine will tell you that certain kinds of light can trigger an attack (particularly those found in big box stores such as Target and Walmart).
Light Sensitivity. Light sensitivity is a hypersensitivity to light. A sudden onset of substantial or even painful light sensitivity (photophobia) may be caused by inflammation in the eye. This may be due to a foreign body in the eye, eye allergy, an infection of the cornea or an inflammation of the iris or uvea. This may also occur after having LASIK or cataract surgery. A gradual onset of less severe sensitivity to light may be associated with cataract or tear film abnormalities such as dry eyes.
