Definition

Noun: - Adhesion between the iris and the lens: A medical condition where the iris (the colored part of the eye) becomes abnormally stuck to the lens of the eye. This adhesion can interfere with the normal flow of fluid within the eye and is often a complication of inflammation.

Usage

Advanced Usage
