The first glaucoma drainage implant was developed in 1966. [2] Following on the success of the Molteno implant, several varieties of device have been developed from the original, the Baerveldt tube shunt, or the valved implants, such as the Ahmed glaucoma valve implant and the later generation pressure ridge Molteno implants.
Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized by raised intraocular pressure (IOP). There are many glaucoma surgeries, and variations or combinations of those surgeries, that facilitate the escape of excess aqueous humor from the eye to lower intraocular pressure, and a few ...
Trabectome surgery has also proven to be a valuable adjuvant at the point of both valved and non-valved tube shunt implantation. When comparing patients undergoing Baerveldt tube implantation alone with those undergoing the same procedure combined with trabectome surgery, both groups showed similar intraocular pressure and visual acuities after ...
During the last 25 years, glaucoma management has been based in the use of pharmaceutical therapies and incisional surgery. [5] MIGS procedures can provide the patient sustained IOP reduction while minimizing the risk and complications associated with glaucoma interventions and decrease the dependence of glaucoma medications.

Secondary glaucoma indicated after congenital cataract surgery is found between 6 and 24% of the cases noted, whereas, secondary glaucoma caused by primary IOL implantation was observed as 9.5%. [5] Additionally, for patients with aphakia and secondary IOL implantation, 15.1% of the cases were determined. [ 5 ]
Symptoms. Atherosclerosis is often referred to as a silent killer, since symptoms often don’t appear or are minimal until it causes severe cardiovascular disease or other complications.
Over many years, glaucoma has been defined by an intraocular pressure of more than 20 mm Hg. Incompatible with this (now obsolete) definition of glaucoma was the ever larger number of cases that have been reported in medical literature in the 1980s and 1990s who had the typical signs of glaucomatous damage, like optic nerve head excavation and thinning of the retinal nerve fiber layer, while ...
