Selective Laser Trabeculoplasty helps preserve sight in people with open-angle glaucoma by producing a change in the biological drainage function of the trabecular meshwork of the eye, typically resulting in a reduction of the raised IOP. The SLT procedure is quick and typically painless, and can be performed as an outpatient procedure. Selective laser trabeculoplasty (SLT) is an advanced surgical treatment for open-angle glaucoma, one of the many types of glaucoma. This procedure results in a biological response that: Increases fluid drainage.   To analyze the results of repeat selective laser trabeculoplasty (SLT). Inclusion criteria: participants with primary or secondary open-angle glaucoma (excluding uveitic) who had undergone SLT ° (SLT 1) with diminution of response over time followed by repeat SLT ° (SLT 2). Six months of follow-up were required and at least 6 months in between SLT 1 and by:   Juzych MS, Chopra V, Banitt MR, et al.

This laser-mediated treatment of the peripheral iris is a valuable tool for opening the chamber angle. Iridoplasty is useful as a stand-alone procedure for the treatment of nonpupillary block angle closure. It may also be used adjunctively for pupillary block angle closure and for open-angle glaucoma in the presence of narrow angles.   The most common treatment paradigm for open-angle glaucoma (OAG) starts with medications to lower intraocular pressure (IOP) and, if unsuccessful, moves on to laser trabeculoplasty followed by.

Selective Laser Trabeculoplasty, or SLT, is a form of laser surgery that is used to lower intraocular pressure in glaucoma. It is used when eye drop medications are not lowering the eye pressure enough or are causing significant side effects.

It can also be used as initial treatment in glaucoma. SLT has been in use for more than 25 years in the. The eye doctor then holds a special lens to the eye. The laser beam is aimed into the eye, and there is a bright light, like a camera flash.

The following are the most common laser surgeries to treat glaucoma. Selective Laser Trabeculoplasty (SLT) For the treatment of primary open-angle glaucoma (POAG). SLT uses a laser that works at very low.

Laser trabeculoplasty (ALT or SLT) is an office based procedure performed to lower eye pressure in patients with open angle glaucoma. Patients whose eye pressure is still too high even though they are already on 1 or more eye medications or are intolerant to some of the eye drops due to allergy or other side-effects are good candidates for.

In conclusion, selective laser trabeculoplasty is successful in the initial and repeat treatment of open-angle glaucomas. This scenario has included patients who have had an initial successful treatment with degree SLT lasting at least 6 months, with the effect wearing off over by: Laser treatment for open-angle glaucoma is called trabeculoplasty and its purpose is to improve the drainage of the aqueous humor out of the eye, which in most cases will lead to an additional decline in pressure.

This laser treatment has both advantages and disadvantages. Selective Laser Trabeculoplasty (SLT) SLT is one of the safest and a very effective treatment for open-angle glaucoma.

This is a pain-free minute procedure that can lower eye pressure up to. Get this from a library. Laser trabeculoplasty for open-angle glaucoma. [Feigenbaum, Ernest.; National Center for Health Services Research and Health Care Technology Assessment (U.S.).

Office of Health Technology Assessment.]. CONCLUSIONS: Selective laser trabeculoplasty was found to be equally efficacious as latanoprost in reducing intraocular pressure in newly diagnosed open-angle glaucoma and ocular hypertension over 12 months, independent of angle pigmentation.

Nonsteroidal antiinflammatory therapy had similar efficacy to steroids after laser by: Albert S Khouri, Robert D Fechtner, in Glaucoma (Second Edition), Laser and Incisional Surgery.

Laser trabeculoplasty may be considered as a first-line intervention for open-angle glaucoma in patients unable or unwilling to use medications, or in certain conditions like pseudoexfoliation or pigmentary glaucoma where it can be very effective.

Laser. Laser trabeculoplasty for open angle glaucoma Glaucoma is a chronic progressive disease of the optic nerve which, if not treated, leads to visual field decay and blindness at end stages.

Intraocular pressure (IOP) decreasing is shown to diminish the progression of the disease, and could be achieved by the chronic use of hypotensive eyedrops. Glaucoma is a group of eye diseases which result in damage to the optic nerve and cause vision loss.

The most common type is open-angle glaucoma, in which the drainage angle for fluid within the eye remains open, with less common types including closed-angle glaucoma and normal-tension glaucoma. Open-angle glaucoma develops slowly over time and there is no factors: Increased pressure in the eye.

The Glaucoma Book is both a comprehensive academic work with evidence-based science and exhaustive bibliographies, and an everyday, pragmatic guide for general ophthalmologists, optometrists, and resident physicians who need immediate answers while examining patients.

Its 92 chapters and 38 sidebar essays range from conventional topics (e.g., open angle 3/5(3). Here are some types of laser surgery for glaucoma: Argon laser trabeculoplasty (ALT): This opens clogs in your eye so fluid can drain out.

Your doctor may treat half of the clogs first, see how Author: Susan Bernstein. Laser Treatment for Open-Angle Glaucoma. A recent, randomized clinical trial demonstrated that laser therapy (the LiGHT trial), specifically selective laser trabeculoplasty (SLT), is an appropriate and effective first-line treatment for open-angle glaucoma.

Indeed, in this study, 74 percent of patients who underwent SLT did not require. Trabeculoplasty. This surgery is for people who have open-angle glaucoma. The eye surgeon uses a laser to make the drainage angle work better.

That way fluid flows out properly and eye pressure is reduced. Iridotomy. This is for people who have angle-closure glaucoma. The ophthalmologist uses a laser to create a tiny hole in the iris. This hole. To evaluate the efficacy of selective laser trabeculoplasty (SLT) in the adjunctive treatment of medically diagnosed open-angle glaucoma and to compare the.

Laser trabeculoplasty To treat open-angle glaucoma, a surgery called laser trabeculoplasty is often used. During trabeculoplasty, a laser makes tiny, evenly spaced burns in the trabecular meshwork. The laser does not create new drainage openings but make the drainage angle work more efficiently.

Laser surgery has become increasingly popular as an intermediate step between drugs and traditional glaucoma surgery. The most common type of laser surgery performed for open-angle glaucoma is called Argon Laser Trabeculoplasty (ALT).

The objective of the surgery is to help fluids drain out of the eye, reducing intra-ocular pressure that can cause damage to the optic. Laser surgery for glaucoma is used to open your eye drainage system, or create a new drainage system.

Glaucoma is caused by fluid buildup behind the eye. This surgery helps decrease eye pressure and slow or prevent further damage and vision loss. You may need surgery on one or both eyes. treatment in open angle glaucoma management.

KEYWORDS: selective laser trabeculoplasty, glaucoma, laser surgery INTRODUCTION Glaucoma can be defined as a group of diseases that features a progressive optic neuropathy accompanied by characteris-tic visual field changes, with or without increased intraoc-ular Size: KB.

Glaucoma refers to a group of disorders related to damage to the optic nerve and elevated pressure in the eye. Glaucoma is divided into open (normal) angle or angle closure.

In open angle (left) the fluid can pass through the pupil and reach the drainage pathway of the eye. Purchase Glaucoma - 2nd Edition. Print Book & E-Book.

Risk factors for the development or. Laser trabeculoplasty effectively reduces intraocular pressure (IOP) in primary open angle glaucoma, with argon laser trabeculoplasty (ALT) and selective laser trabeculoplasty (SLT) showing equivalent outcomes. However, it is unclear which laser modality is more effective in pseudoexfoliation (PXE) glaucoma.

Glaucoma is not just one eye disease, but a group of eye conditions resulting in optic nerve damage, which causes loss of vision. Abnormally high pressure inside your eye (intraocular pressure) is in most cases the cause of this damage.

Glaucoma is the second leading cause of blindness and can damage your vision so gradually you may not notice any loss of vision until. Objective: To compare the outcomes of selective laser trabeculoplasty (SLT) on treatmentnaive, primary open-angle glaucoma (POAG) patients with those of SLT on patients previously treated medically and/or surgically.
