Performed either with standard surgical instruments or a laser, it is typically used to decrease intraocular pressure in patients with angle-closure glaucoma. A laser peripheral iridotomy (LPI) is the application of a laser beam to selectively burn a hole through the iris near its base.
Trabeculoplasty is a laser treatment for glaucoma. It is done on an argon laser equipped slit lamp, using a Goldmann gonioscope lens mirror. Specifically, an argon laser is used to improve drainage through the eye's trabecular meshwork, from which the aqueous humour drains.
Both laser and conventional surgeries are performed to treat glaucoma. Surgery is the primary therapy for those with congenital glaucoma. Generally, these operations are a temporary solution, as there is not yet a cure for glaucoma. Canaloplasty. Canaloplasty is a nonpenetrating procedure using microcatheter technology.
Trabeculectomy is a surgical procedure used in the treatment of glaucoma to relieve intraocular pressure by removing part of the eye's trabecular meshwork and adjacent structures. It is the most common glaucoma surgery performed and allows drainage of aqueous humor from within the eye to underneath the conjunctiva where it is absorbed.
Micro-invasive glaucoma surgery (MIGS) is the latest advance in surgical treatment for glaucoma, which aims to reduce intraocular pressure by either increasing outflow of aqueous humor or reducing its production. MIGS comprises a group of surgical procedures which share common features.
Surgical iridectomy is commonly indicated and performed in the following cases: [citation needed] Cataract surgery in a glaucoma patient. Combined procedure for cataract and glaucoma. Acute closed-angle glaucoma. Posterior capsular tears with vitreous loss. Implantation of anterior chamber IOL.
Particularly, these include operations done on ciliary body in an attempt to control glaucoma, since highly safer surgeries for glaucoma, including lasers, nonpenetrating surgery, guarded filtration surgery, and seton valve implants have been invented.
Treatment, by lowering the intraocular pressure, may help decrease the risk of vision loss and damage to the eye from glaucoma. Treatment options include pressure-lowering 'antiglaucomatous' eye drops, surgery, and/or laser eye surgery.
The procedure is safe and effective for treating indicated retinal disorders, such as tears and glaucoma. It is typically an outpatient procedure lasting 15 to 20 minutes. The procedure is not entirely without risk. Damage will occur to light sensitive cells of the retina cauterised by the laser which will result in some loss of vision.
Among different laser therapies, laser peripheral iridotomy and laser trabeculoplasty are the most common procedures for secondary glaucoma. Both methods involve creating new outlets for the aqueous humour to flow out of, effectively reducing the IOP.
