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 ...
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 ...
Increased intraocular pressure (IOP) is the main and only modifiable risk factor, attributed to the progression of the disease. During the last 25 years, glaucoma management has been based in the use of pharmaceutical therapies and incisional surgery. [5]
Poor compliance with medications and follow-up visits is a major reason for treatment failure and disease progression in glaucoma patients. Poor adherence could lead to increased complication rates, thus increasing the need of non-pharmacological interventions including surgery.
In acute angle-closure glaucoma cases, surgical iridectomy has been superseded by Nd:YAG laser iridotomy, because the laser procedure is much safer. Opening the globe for a surgical iridectomy in a patient with high intraocular pressure greatly increases the risk of suprachoroidal hemorrhage , with potential for associated expulsive hemorrhage .
Cyclodestruction or cycloablation is a surgical procedure done in management of glaucoma. Cyclodestruction reduces intraocular pressure (IOP) of the eye by decreasing production of aqueous humor by the destruction of ciliary body. Until the development of safer and less destructive techniques like micropulse diode cyclophotocoagulation and ...
