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. These are ...
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 that lower IOP by decreasing the production of ...
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. [1]
Uveitis–glaucoma–hyphaema (UGH) syndrome, also known as Ellingson syndrome, is a complication of cataract surgery, caused by intraocular lens subluxation or dislocation. The chafing of mispositioned intraocular lens over iris , ciliary body or iridocorneal angle cause elevated intraocular pressure (IOP) anterior uveitis and hyphema .
Reoperation after failed trabeculectomy or tube shunt is very challenging. Trabectome surgery is a minimally invasive alternative to a repeat filter or shunt. Studies of patients undergoing trabectome surgery after a failed tube shunt have shown a statistically significant reduction in intraocular pressure after one year [42].
Trabeculectomy is the most common invasive glaucoma surgery. It is highly effective in the treatment of advanced glaucoma as demonstrated in major glaucoma studies. [citation needed] Even if a prior trabeculectomy has failed a second trabeculectomy can be performed at a different site. If scarring is the main reason, anti-fibrotic and anti ...
Primary congenital glaucoma is classified into three subtypes: [4] true congenital glaucoma, which causes signs of increased intraocular pressure within the first month of life, infantile glaucoma, which presents between one month and three years, and; juvenile glaucoma, which becomes clinically apparent after three years of age and before age 40.
Aphakic and pseudophakic glaucoma: Aphakic glaucoma is a common side-effect of cataract surgery which causes an increase in IOP. [ 2 ] Corticosteroid -induced glaucoma: Corticosteroids is a risk factor for the development of secondary glaucoma, as there had been increased IOP observed as a drug side-effect.
