10 Symptoms of Measles
Symptom #10: Photophobia
Photophobia is sensitivity to light. Photophobia can be caused by conditions that are either localized to the eyes such as irritation of the iris (also called iritis) or conditions that affect the body as a whole such as measles.
Measles can cause photophobia such that the patient is unable to tolerate light. As a result, the person with measles will tend to squint or close their eyes in order to reduce or cut out the light entering the eyes. Additionally, the patient may also experience nausea or headache. These symptoms worsen with increased brightness of the light. Photophobia is more common in individuals whose eyes are light colored than those with dark colored eyes.
