What is Aqueous Flare?

Aqueous flare is a health term used in ophthalmology to describe the visibility of protein in the aqueous humor, the clear fluid that fills the front part of the eye between the lens and the cornea. The term is often associated with inflammation within the eye.

The aqueous humor normally contains a small amount of protein, but when there is inflammation in the eye, the protein concentration may increase, leading to a cloudy appearance of the aqueous humor. This increased protein concentration results in the phenomenon known as aqueous flare.

Ophthalmologists may assess aqueous flare as part of a comprehensive eye examination. It is often measured using a technique called laser flare photometry. Elevated levels of aqueous flare can be indicative of various eye conditions, including uveitis (inflammation of the uvea, the middle layer of the eye), iritis, or other inflammatory eye diseases.

Monitoring aqueous flare is important for diagnosing and managing ocular inflammation, as it can help guide treatment decisions and assess the effectiveness of interventions. If you have concerns about your eye health or experience symptoms such as eye redness, pain, or vision changes, it is crucial to seek prompt evaluation by an eye care professional.
