Doctor's Notes on Eye Pain
Eye pain is pain or discomfort that originates within the structures of the eye or the surrounding structures, including the eyelids, conjunctival membranes, cornea, or muscles and nerves that control the eye. There are a number of different causes of eye pain, which can include corneal infections, corneal abrasions, conjunctivitis (pink eye), blepharitis (inflammation of the eyelids), glaucoma, optic neuritis, and sinusitis, among others. A foreign object in the eye is also a source of eye pain, along with trauma or injury to the eye area. Signs and symptoms associated with eye pain vary depending on the exact cause of the pain. These can include redness, swelling, bleeding, excessive tearing, vision disturbances, headache, nausea, and vomiting. Other associated symptoms can include the sensation of something in the eye, such as a gritty or irritated feeling.
