PHOTOPHOBIA:
DIAGNOSTIC WORKUP
(Algorithmic Diagnosis of Symptoms and Signs)
A careful eye examination including tonometry and slit lamp examination should be done. A referral to an ophthalmologist may be necessary to accomplish this. If there is nuchal rigidity, a CT scan followed by a spinal tap should be done in conjunction with a neurologic consultation. If there is fever without nuchal rigidity, the workup can proceed as outlined on
page 168
. A histamine test may be helpful in diagnosing migraine.

Photophobia:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
If the patient reports photophobia, find out when it began and how severe it is. Did it follow eye trauma, a chemical splash, or exposure to the rays of a sun lamp? If photophobia results from trauma, avoid manipulating the eyes. Ask the patient about eye pain and have him describe its location, duration, and intensity. Does he have a sensation of a foreign body in his eye? Does he have other signs and symptoms, such as increased tearing and vision changes?
Next, take the patient’s vital signs and assess his neurologic status. Assess visual activity, unless the cause is a chemical burn. Follow this with a careful eye examination, inspecting the eyes’external structures for abnormalities. Examine the conjunctiva and sclera, noting their color. Characterize the amount and consistency of any discharge. Then check pupillary reaction to light. Evaluate extraocular muscle function by testing the six cardinal fields of gaze, and test visual acuity in both eyes.
During your assessment, keep in mind that although photophobia can accompany life-threatening meningitis, it isn’t a cardinal sign of meningeal irritation.

Photophobia:
Physical assessment
(Signs & Symptoms: A 2-in-1 Reference for Nurses)
Take the patient’s vital signs and assess neurologic status. Assess visual activity, unless the cause is a chemical burn. Follow this with a careful eye examination, inspecting the eyes’external structures for abnormalities. Examine the conjunctiva and sclera, noting their color. Characterize the amount and consistency of any discharge. Then check pupillary reaction to light. Evaluate extraocular muscle function by testing the six cardinal positions of gaze, and test visual acuity in both eyes. (See Testing the six cardinal positions of gaze, page 464.)
