LAMELLAR CATARACT Meaning and Definition

1. A lamellar cataract is a type of cataract that affects the lens of the eye, resulting in a specific pattern of opacity or cloudiness. The term "lamellar" refers to the layered appearance of this type of cataract, as it is characterized by the presence of distinct layers of opacity within the lens.

   Typically, a lamellar cataract affects only a portion of the lens, allowing some areas to remain clear. This creates a unique appearance resembling the rings of a tree, with concentric layers of cloudiness surrounding a central clear zone. The opacity may vary in intensity and density, leading to gradual vision impairment.

   The development of a lamellar cataract can be attributed to various factors, including genetic mutations, metabolic disorders, trauma, or certain systemic diseases. It may be present at birth or develop later in life.

   Symptoms of lamellar cataract can include blurred or cloudy vision, difficulty seeing in dim light, increased sensitivity to glare, and color vision abnormalities. If left untreated, lamellar cataracts can lead to significant vision loss and impact daily activities.

   Treatment for lamellar cataract generally involves surgical intervention. Cataract surgery aims to remove the cloudy lens and replace it with an artificial intraocular lens (IOL) to restore clear vision. The specific surgical approach and techniques may vary depending on the severity and location of the cataract.

   Regular eye examinations and early detection are crucial for timely intervention and optimal visual outcomes for individuals with lamellar cataracts.

2. One in which the opacity is limited to certain of the layers of the lens external to the nucleus.

Etymology of LAMELLAR CATARACT

The word "lamellar" originates from the Latin word "lamella", which means a thin plate or sheet. In the context of cataracts, the term "lamellar" refers to the layered or lamellar appearance of the opacities in the lens of the eye. "Cataract" comes from the Latin word "cataracta", which means a waterfall or a portcullis. This term was likely used to describe the clouding or opaque appearance of the lens, resembling the flowing water or descending gate-like structure of a waterfall. Thus, "lamellar cataract" describes a specific type of cataract where the opacities in the lens occur in a layered or lamellar pattern.
