TRABECULOPLASTIES Meaning and
Definition
-
Trabeculoplasties is a medical term that refers to a procedure used to treat glaucoma, a condition characterized by increased intraocular pressure in the eye. The word is derived from the combination of two parts: "trabeculae," which are small, beam-like structures that provide support and structure within the eye, and "plasties," which refers to the surgical procedure of reshaping or altering a part of the body.
In the context of ophthalmology, trabeculoplasties specifically involves the use of laser therapy to modify the trabecular meshwork, a network of tissue responsible for draining fluid from the eye. By carefully applying laser energy, the trabecular meshwork is stimulated, resulting in an opening up of the drainage channels and improved fluid outflow. This reduction in intraocular pressure helps alleviate the symptoms associated with glaucoma and prevents further optic nerve damage.
The trabeculoplasties procedure can be performed using two different techniques: argon laser trabeculoplasty (ALT) and selective laser trabeculoplasty (SLT). ALT utilizes a high-energy laser to treat approximately 100 spots on the trabecular meshwork, while SLT employs a lower-energy laser to selectively target specific cells in the meshwork, leaving the surrounding tissue unaffected.
Trabeculoplasties is often considered as an alternative treatment option for glaucoma patients who have not achieved satisfactory results with medication or who have difficulty complying with the prescribed eye drop regimen. It is a relatively quick and safe procedure, performed on an outpatient basis, and generally leads to a reduction in intraocular pressure, thereby preventing the progression of glaucoma and preserving the patient's vision.

Etymology of TRABECULOPLASTIES
The etymology of the word "Trabeculoplasties" is as follows:
The term "trabeculoplasties" is a combination of two root words: "trabeculo" and "plasty".
1. "Trabeculo" is derived from the Latin word "trabecula", which means "small beam" or "crossbeam". In medical terminology, the trabecular meshwork (TM) refers to a web-like structure in the eye that helps drain aqueous humor, hence playing an important role in regulating the intraocular pressure. Hence, "trabeculo" in this context refers to the trabecular meshwork.
2. "Plasty" comes from the Greek word "plastikos", which means "fit for molding" or "shaping".
