CASEOUS CATARACT Meaning and
Definition
-
Caseous cataract is a medical term referring to a specific type of cataract that affects the lens of the eye. A cataract is a condition characterized by a clouding or opacity of the lens, which can impair vision. Caseous cataract is particularly distinguished by a specific appearance and texture of the opacity.
The term "caseous" is derived from the Latin word "caseus," meaning cheese. In this context, "caseous" refers to the consistency and appearance of the cataract, which resembles the texture of cheese. The opacity appears as a solid, opaque, and whitish-yellowish mass within the lens.
Caseous cataracts usually develop as a result of certain underlying conditions or diseases, such as tuberculosis or toxoplasmosis. These underlying conditions lead to the accumulation of proteinaceous material within the lens, causing it to become thickened and opaque.
The symptoms of caseous cataract include gradual vision loss, blurred or distorted vision, and increased sensitivity to light. Treatment typically involves surgical intervention to remove the cloudy lens and replace it with an artificial intraocular lens.
It is worth noting that while caseous cataracts are a distinct type of cataract, there are several other types that can also occur, including nuclear, cortical, and posterior subcapsular cataracts. Each type differs in terms of their location within the lens or the specific changes they cause.
