Diagnostic tests for Photophobia:

Various tests are used in the diagnosis of Photophobia. Some of these are listed below :

  • Eye examination
    • Inspect the eye noting the nature of redness, if present. This will help delineate conjunctivitis, keratitis, iritis, uveitis, glaucoma and corneal ulceration
    • Inspect under the upper eyelid for foreign bodies, fine follicles (which indicate a viral infection) or for a cobblestone appearance (which indicates allergic conjunctivitis)
    • Fluorescein and Rose Bengal staining of the surface of the eye may show small defects in the cornea suggesting corneal ulceration. Branch like ulceration is diagnostic of herpes simplex infection of the eye
    • Visual acuity - in both eyes with and without glasses (if worn) to determine any refractive error. Reduced visual acuity may suggest herpes simplex infection, corneal ulcer, acute iritis or acute glaucoma (haloes around lights).
    • Examination of pupils and the pupil reflexes. A dilated pupil would suggest glaucoma, a small constricted pupil may suggest acute iritis
    • Ophthalmoscopy and slit lamp examination - to examine the optic nerve, macula and retina.
