aqueous flare


Also found in: Dictionary, Thesaurus, Encyclopedia.

a·que·ous flare

Tyndall phenomenon observed in the fluid of the anterior chamber of the eye.

aqueous flare

During slit lamp examination of the eye, an abnormal appearance of the beam of light as it travels through the anterior chamber. The flare is caused by light reflecting off proteins in the aqueous humor. It is found in patients with inflammation in the anterior chamber.

flare, aqueous

Scattering of light seen when a slit-lamp beam is directed, obliquely to the plane of the iris, into the anterior chamber. It occurs as a result of increased protein content, and usually inflammatory cells, in the aqueous humour. Visual impairment depends on the intensity of the flare. It is a sign of intraocular inflammation. See Tyndall effect; iritis; uveitis.

Furthermore, further histological or biochemical analysis to determine whether the source of increased aqueous flare values resulted from the breakdown of the BAB itself or simply from proteins diffusing from the posterior segment caused by the breakdown of the blood-retinal barrier.

On the 14th post-operative day, AC cells were present in 4(7.4%) eyes in Group A and in 3(5.55%) eyes in Group B (p>0.999), while aqueous flare was present in 5(9.25%) eyes in Group A and 9(16.66%) eyes in Group B (p=0.391) (Table-3)
