Relationship between sleep position and glaucoma progression.

Curr Opin Ophthalmol 2019 Nov;30(6):484-490

Department of Ophthalmology, Stony Brook University, Stony Brook, New York, New York, USA.

Purpose Of Review: As humans spend a considerable portion of life in the horizontal position, it is vital to better understand the effect of sleep position on glaucoma.

Recent Findings: The mean positional increase from the supine position to the lateral decubitus position (LDP) in recent literature is less than 2 mmHg for each eye in its dependent position and less than 1 mmHg in the nondependent position. The right LDP is most commonly favored sleeping position. Read More

[Diode and argon trabeculoplasty in primary open-angle glaucoma treatment].

Vestn Oftalmol 2019 ;135(4):103-107

Research Institute of Eye Diseases, 11A Rossolimo St., Moscow, Russian Federation, 119021.

Laser trabeculoplasty is one of the methods used to decrease intraocular pressure (IOP) as part of comprehensive glaucoma treatment. Argon laser trabeculoplasty (ALT) and diode laser trabeculoplasty (DLT) are two of the most widely used laser trabeculoplasty techniques. The mechanism of its hypotensive action is based on the effect that laser emission photocoagulate has on trabecular meshwork and subsequent outflow facilitation, but the difference in wavelength and emission energy determine the difference in direct laser action and the features of postoperative clinical appearance.

[Perioperative Anti-inflammatory Treatment in Glaucoma Surgery].

Klin Monbl Augenheilkd 2019 May 16;236(5):647-652. Epub 2019 May 16.

Augenklinik, Universitätsmedizin Mainz.

Many clinical studies have demonstrated the benefit of topical anti-inflammatory medication before and after glaucoma surgery, especially for trabeculectomy, and that they improve the long term outcome. Pre- and postoperative topical steroids improve the outcome of trabeculectomy, but duration and intensity of treatment should be adapted individually. Systemic steroid or oral immunomodulation have significant impact on the outcome in uveitic glaucoma, but not in other glaucoma subtypes. Read More

Acute primary angle closure-treatment strategies, evidences and economical considerations.

Eye (Lond) 2019 01 22;33(1):110-119. Epub 2018 Nov 22.

Department of Ophthalmology & Visual Sciences, The Chinese University of Hong Kong, Hong Kong SAR, People's Republic of China.

Acute primary angle closure requires emergency management that involves a rapid lowering of the intraocular pressure and resolution of relative pupil block - the most common mechanism of angle closure. Emergency strategies for lowering intraocular pressure include medical treatment and argon laser peripheral iridoplasty. Anterior chamber paracentesis and diode laser transcleral cyclophotocoagulation may be considered in special situations. Read More

A Review of the Clinical Usefulness of Selective Laser Trabeculoplasty in Exfoliative Glaucoma.

Adv Ther 2018 05 11;35(5):619-630. Epub 2018 Apr 11.

Department of Ophthalmology, Hospital Universitario "Principe de Asturias," Universidad de Alcalá, Alcalá de Henares, Spain.

In the last decade, selective laser trabeculoplasty (SLT) has been commonly used in the management of several different types of glaucoma, as either primary or adjunct therapy. The technique has an excellent safety profile and is at least as effective as argon laser trabeculoplasty. Although the actual mechanism of action of SLT remains unclear, evidence has shown that it does not induce morphologically evident trabecular meshwork alterations. Read More

Evaluating selective laser trabeculoplasty versus argon laser trabeculoplasty in pseudoexfoliation glaucoma patients.

Can J Ophthalmol 2018 02 27;53(1):70-75. Epub 2017 Sep 27.

Department of Ophthalmology & Visual Sciences, Dalhousie University, Halifax, N.S.

Objective: 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. This study aims to compare the effectiveness of ALT and SLT in PXE glaucoma. Read More

Laser Management of Glaucoma in Exfoliation Syndrome.

J Glaucoma 2018 07;27 Suppl 1:S91-S94

Department of Ophthalmology and Visual Sciences, University of Alberta, Edmonton, AB, Canada.

Argon laser trabeculoplasty as well as selective laser trabeculoplasty can be used in patients with exfoliation syndrome with similar safety and efficacy. However, treatment effect may abruptly reverse and patients need to be followed regularly to monitor intraocular pressure control. Newer laser treatment modalities including micropulse laser trabeculoplasty, titanium sapphire laser trabeculoplasty and pattern scanning trabeculoplasty show promising results but need to be studied in exfoliation patients.

Selective laser trabeculoplasty: past, present, and future.

A Garg G Gazzard

Eye (Lond) 2018 05 5;32(5):863-876. Epub 2018 Jan 5.

Department of Glaucoma, Moorfields Eye Hospital, London, UK.

Over the past two decades, selective laser trabeculoplasty (SLT) has increasingly become an established laser treatment used to lower intraocular pressure in open-angle glaucoma and ocular hypertensive patients. In this review we trace the origins of SLT from previous argon laser trabeculoplasty and review the current role it has in clinical practice. We outline future directions of SLT research and introduce emerging technologies that are further developing this intervention in the treatment paradigm of glaucoma. Read More

Perioperative medications for preventing temporarily increased intraocular pressure after laser trabeculoplasty.

Cochrane Database Syst Rev 2017 02 23;2:CD010746. Epub 2017 Feb 23.

Ophthalmology and Visual Sciences, Kellogg Eye Center, University of Michigan, 1000 Wall Street, Ann Arbor, Michigan, USA, 48105.

Background: Glaucoma is the international leading cause of irreversible blindness. Intraocular pressure (IOP) is the only currently known modifiable risk factor; it can be reduced by medications, incisional surgery, or laser trabeculoplasty (LTP). LTP reduces IOP by 25% to 30% from baseline, but early acute IOP elevation after LTP is a common adverse effect. Read More
