Photophobia may be due to diseases such as keratitis, acute iridocyclitis and uveitis, intermittent strabismus, glaucoma, and inverted eyelashes.
1. Keratitis: Keratitis can cause photophobia due to inflammatory irritation, corneal epithelial defects, and exposure of nerve endings.
2. Acute iridocyclitis and uveitis: iridocyclitis causes pupil constriction and slow reaction to light, resulting in photophobia.
3. Intermittent exotropia: Patients with intermittent exotropia can easily close one eye when encountering bright light to overcome the diplopia interference caused by bright light.
4. Glaucoma: Glaucoma is a common disease in ophthalmology, usually caused by elevated intraocular pressure, which usually manifests itself as tearing, photophobia, foreign body sensation, vision loss of varying degrees, and in more severe cases, swelling and pain in the eyes.
5. Inverted eyelashes: As the eyelashes of patients with inverted eyelashes will bruise the cornea causing corneal epithelial incompleteness, punctate and diffuse corneal epithelial damage, in which case photophobia occurs, so it can be observed that many inverted eyelashes in the child afraid of the sun, see the light and bow his head, take pictures with a flash and then close his eyes.
Patients with symptoms of photophobia should go to the hospital in time for examination and active treatment under the guidance of the doctor. Usually pay attention to eye hygiene, avoid bright light stimulation.
