Anterior chamber cells

What it means

Tiny deposits corresponding to cells floating in the anterior chamber of the eye. This appearance is typically associated with intraocular inflammation leading to breakdown of the blood-aqueous barrier and resulting in an increase in the number of cells and in the aqueous humor. Grading (SUN Working Group) is performed by estimating the number of cells in a 1 mm by 1 mm slit beam field, employing adequate light intensity and magnification on a slit lamp.
