What is another name for a trabeculectomy?

A trabeculectomy is a surgical procedure primarily performed to treat glaucoma by creating a new drainage pathway for the aqueous humor. This helps lower intraocular pressure by facilitating the outflow of fluid from the eye. The operation results in the formation of a 'filtering bleb', which is a dome-shaped elevation on the surface of the eye, where the filtered fluid collects. This bleb is essential for the effectiveness of the procedure, as it is through this structure that the fluid drains out of the eye.

The other options refer to entirely different procedures. Lens replacement involves substituting a damaged or cataracted lens with an artificial one, while a corneal graft is a procedure to replace a damaged or diseased cornea. Retinal detachment repair focuses on reattaching the retina to its underlying tissue. Each of these procedures addresses distinct ophthalmic conditions but does not relate directly to the concept of a trabeculectomy or the formation of the filtering bleb.
