Introduction Photophobia, which is commonly referred to as "glare" or "Beiguang", is caused by the sensory nerves in the eye being stimulated, causing abnormalities in the eyes. It is very glaring to the daily light, and even serious Blinking, more common in corneal foreign body, keratitis and corneal trauma, iritis, conjunctivitis can also cause photophobia. It is worth noting that when infants and young children appear photophobia, pay attention to whether there is congenital glaucoma. In addition, the expansion will also cause photophobia, and it will be better after the pupil is reduced.

Diagnosis of photophobia:

Diagnosis First, pay attention to whether it exists alone or both, the duration of onset, the history of infinite trauma or eye surgery, the history of local or systemic medication, and whether there are migraine, cluster headache, acute infection or other systemic diseases. If both photophobia and tears coexist, attention should be paid to inflammation or trauma to the front of the eye. The application of mydriatic medicine can cause photophobia, but there is little tearing.

If the patient finds that the patient has a large dilated pupil or an iris defect, there will naturally be photophobia. If accompanied by a sudden unilateral pupil dilated, it is mostly caused by trauma or drug. When there is inflammation of the cornea or iris or trauma, the boat must have photophobia and tears.

Differential diagnosis

Photophobia should be differentiated from the following symptoms:

Tears: visible in chronic lacrimal gland inflammation, Mikldiez syndrome, external punctum, obstruction of lacrimal duct, tears and tears, bronchial asthma, acute rhinitis, cluster headache, drug-induced irritation. Photophobia and tears coexist: seen in corneal epithelial damage, inflammation and foreign body, conjunctivitis, iris eyelashes, internal eye surgery, measles, whooping cough, influenza and so on.
