BACKGROUND: Glaucoma is the second leading cause of blindness in the world. Angle closure glaucoma accounts for 25% of all glaucoma, with Asia having the highest rate. Angle closure is an anatomical variation, making the Inuit, Chinese, and other Asians more susceptible. Current treatments include medical, laser, and surgical modalities. PURPOSE: To identify the current treatment protocols for primary angle closure. DISCUSSION: The current general protocol to treat angle closure is to lower the intraocular pressure with medications and perform laser iridotomy...

Plateau iris configuration describes an anatomic abnormality in which large or anteriorly positioned pars plicata push the iris root forward, thereby narrowing the anterior chamber angle. Plateau iris syndrome (PIS) is diagnosed if the angle remains occludable, either spontaneously or pharmacologically, after iridotomy. PIS has traditionally been treated with chronic pilocarpine or laser peripheral iridoplasty. A series of 9 eyes of 6 patients with PIS, diagnosed by dark room provocative testing and ultrasound biomicroscopy (UBM) following iridotomy, underwent cataract extraction and endoscopic cyclophotocoagulation (ECP)...

BACKGROUND: We describe two cases of recurrent acute angle-closure attack in patients with plateau iris syndrome after cataract extraction. Argon laser peripheral iridoplasty and cataract extraction have been used to reduce the occurrence of acute angle-closure attack in plateau iris syndrome although the risk cannot be completely eliminated. There is no consensus on the long term management of plateau iris syndrome. This is, as far as we know, the first case report of recurrent acute angle-closure attack in plateau iris syndrome after cataract extraction...

Primary angle-closure glaucoma (PACG) is a progressive optic nerve degeneration and is defined as a glaucomatous optic neuropathy with associated characteristic enlargement of optic disc cupping and visual field loss that is secondary to ocular hypertension caused by closure of the drainage angle. Angle closure is caused by appositional approximation or adhesion between the iris and the trabecular meshwork. The main treatment strategy for PACG lies in the reduction of intraocular pressure, reopening of the closed angle, and possible prevention of further angle closure...

PURPOSE: To report on the safety and efficacy of Nd: YAG laser goniopuncture (LGP) for postsurgical intraocular pressure increase after deep sclerectomy (DS) in a consecutive cohort of open-angle glaucoma patients. METHODS: This case series included 56 eyes from 49 consecutive patients who underwent LGP between November 2008 and March 2015. Prior to LGP, patients had undergone DS augmented with mitomycin C and injectable cross-linked hyaluronic acid implant between October 2008 and May 2014...

PURPOSE: To determine the effectiveness of argon laser peripheral iridoplasty (ALPI) in primary angle closure (PAC) and primary angle-closure glaucoma (PACG). DESIGN: Randomized controlled trial. PARTICIPANTS: Eighty PAC or PACG subjects who underwent laser iridotomy (LI) and had at least 180° of persistent appositional angle closure and intraocular pressure (IOP) of more than 21 mmHg were enrolled. METHODS: Subjects were randomized to receive either 360° ALPI (Visulas 532s; Carl Zeiss Meditec, Jena, Germany) or medical therapy (Travoprost 0...

Primary angle-closure glaucoma is potentially a devastating disease, responsible for half of glaucoma-related blindness worldwide. Angle closure is characterized by appositional approximation or contact between the iris and trabecular meshwork. It tends to develop in eyes with shallow anterior chambers, anteriorly positioned or pushed lenses, and angle crowding. Risk of primary angle-closure glaucoma is high among women, the elderly and the hyperopic, and it is most prevalent in Asia. Investigation into genetic mechanisms of glaucoma inheritance is underway...

AIM: To investigate the efficacy and safety of krypton laser peripheral iridoplasty (LPIP) for Chinese patients with primary angle closure (PAC) or primary angle-closure glaucoma (PACG) status post laser iridotomy in reversing the positive results of the dark room provocative test (DRPT). METHODS: This study was prospective, noncomparative, interventional case series. Thirty-three patients (thirty-eight eyes) with PAC or PACG status post patent laser iridotomy and maintained normal intraocular pressure (IOP) but with positive DRPT results were enrolled...

CASE REPORT: We present a case of plateau iris and glaucoma due to multiple unilateral iridociliary cysts. The patient was treated with iridotomy Nd: YAG laser and 360° iridoplasty, without achieving pressure control. Phacoemulsification improved the hypertension. Dynamic gonioscopy and OCT of the anterior chamber was also performed before and after treatment. DISCUSSION: Iridociliary cysts are a benign condition that can cause iris plateau configuration, and can produce a difficult to treat ocular hypertension...

PURPOSE: To assess the prevalence and treatment outcomes of angle-closure mechanisms other than pupillary block in a population of Brazilian patients. METHODS: A retrospective chart review was conducted to evaluate patients who had undergone laser peripheral iridotomy (LPI) due to occludable angles at a single institution between July 2009 and April 2012. An occludable angle was defined as an eye in which the posterior trabecular meshwork was not visible for ≥180° on dark-room gonioscopy...

PURPOSE: To compare changes in the prelamina and lamina of patients with POAG and acute primary angle-closure (APAC) after IOP reduction. METHODS: We analyzed 20 patients with POAG who were scheduled to undergo glaucoma surgery and 17 patients with APAC scheduled for laser peripheral iridoplasty. Horizontal B-scans of the optic nerve head were obtained using Heidelberg Spectralis optical coherence tomography. The prelaminar position (PLP), laminar position (LP), and prelaminar thickness (PLT) were measured...

Plateau iris syndrome has been described as persistent angle narrowing or occlusion with intraocular pressure elevation after peripheral iridotomy due to the abnormal plateau iris configuration. Argon laser peripheral iridoplasty (ALPI) is an effective adjunct procedure to treat plateau iris syndrome. Classic theory suggests that the laser causes the contraction of the far peripheral iris stroma, "pulls" the iris away from the angle, and relieves the iris-angle apposition. We report a case of plateau iris syndrome that was successfully treated with ALPI...

PURPOSE: To analyze the anatomical and functional outcome of glued intra ocular lens (IOL) implantation technique and its modifications. DESIGN: Retrospective observational case series. METHODS: This is a retrospective analysis of the patients who underwent glued intra ocular lens implantation from December 2007 to August 2010.
