Excimer laser trabeculostomy
Excimer Laser Trabeculostomy (pronunciation: eks-uh-mer lay-zer tra-byoo-luh-stoh-mee) is a medical procedure used in the treatment of Glaucoma, a condition that damages the eye's optic nerve and can result in vision loss and blindness.
Etymology
The term "Excimer Laser Trabeculostomy" is derived from three words. "Excimer" is a portmanteau of "excited" and "dimer", referring to the type of laser used in the procedure. "Trabeculostomy" is derived from "trabeculum", a part of the eye's drainage system, and "-stomy", a suffix in medical terminology meaning "creating an opening".
Procedure
In an Excimer Laser Trabeculostomy, an Excimer Laser is used to create an opening in the Trabecular Meshwork, a part of the eye's drainage system. This allows fluid to drain more effectively from the eye, reducing intraocular pressure and helping to prevent damage to the optic nerve.
