Adherent leucoma, also known as corneal scar, is a condition that affects the cornea, resulting in a white, opaque area on the eye's surface. Synonyms for this condition include corneal opacity, corneal haze, and corneal clouding. These terms describe the same phenomenon, wherein the cornea becomes damaged or scarred, leading to a loss of transparency. Adherent leucomas can occur due to trauma, infection, or inflammation. Regardless of the term used, the underlying issue remains the same, with visual impairment often accompanying this condition. Treatment options may involve surgery, such as corneal transplantation, or the use of contact lenses to improve vision.
