PYRAMIDAL CATARACT Meaning and
Definition
-
A pyramidal cataract is a specific type of cataract that affects the lens of the eye, resulting in a distinct pyramidal or cone-shaped opacity. Cataract refers to the clouding of the normally clear lens of the eye, leading to blurry or impaired vision.
The term "pyramidal" is used to describe the shape of the opacity that develops within the lens. It refers to a formation resembling a pyramid or cone, where the opacity gradually narrows to a point. This distinguishing shape differentiates pyramidal cataract from other types of cataracts.
Pyramidal cataracts can be congenital, meaning they are present at birth, or they may develop later in life due to various factors such as genetic abnormalities, metabolic disorders, or trauma to the eye. Congenital pyramidal cataracts are usually caused by genetic mutations that affect the development of lens fibers.
Symptoms of pyramidal cataract may include reduced visual acuity, blurred or distorted vision, sensitivity to light, and difficulty with color discrimination. Treatment typically involves surgical removal of the cloudy lens and replacement with an artificial intraocular lens (IOL). The surgery aims to restore clear vision and improve the patient's quality of life.
In summary, a pyramidal cataract is a type of cataract characterized by a cone-shaped opacity within the lens of the eye. It can be present at birth or acquired later in life and requires surgical intervention for visual restoration.
