PURPOSE OF REVIEW: Angle closure glaucoma is a prominent burden for the worldwide health system. Because this disorder is commonly asymptomatic, and can lead to irreversible blindness, the proper screening and early management of this disease can be critical. The definitions of angle closure and consequently its treatment guidelines have been dynamically modified and updated in the past decades. Surgical and laser techniques have been adapted to address the different mechanisms involved in the manifestation of the disease and properly prevent its progression in different stages...

PURPOSE: The efficacy and sufficiency of a healthcare system is directly related to the knowledge and skills of graduates working in the system. In this regard, many different assessment methods have been proposed to evaluate various skills of the learners. Video Observation of Procedural Skills (VOPS) is one newly-proposed method. In this study we aimed to compare the results of the VOPS method with the more commonly used Direct Observation of Procedural Skills (DOPS). METHODS: In this prospective study conducted in 2012, all 10 ophthalmology residents of post graduate year 4 were selected for participation...

AIM: To evaluate anterior chamber biometric factors and intraoperative metrics associated with the intraocular pressure (IOP) reduction after phacoemulsification in non-glaucomatous pseudoexfoliative syndrome (PXS) eyes. METHOD: Thirty-three patients were enrolled in this prospective interventional study. Images were excluded if they had poor quality, poor perpendicularity or inability to locate sclera spurs. Anterior chamber depth (ACD), anterior chamber area (ACA), iris thickness, iris area, iris curvature, lens vault, angle opening distance (AOD500, AOD750) and trabecular iris space area (TISA500, TISA750) were measured in qualified images using the Zhongshan Angle Assessment Program and compared preoperatively and 3 months postoperatively...

PURPOSE: To compare long term efficacy of phacoemulsification in the early management of acute primary angle closure (APAC) after aborting an acute attack and performing laser peripheral iridotomy (LPI). METHODS: In this nonrandomized comparative prospective study, we included 35 subjects presenting with APAC who had responded to medical treatment and LPI with intraocular pressure (IOP) less than 25 mmHg. Twenty patients with visually significant cataract with visual acuity of <20/30 were assigned to the "Phaco/LPI" group and underwent phacoemulsification within 6 weeks of the attack...

PURPOSE: To evaluate the relationship between lens position parameters and intraocular pressure (IOP) reduction after cataract surgery in patients with primary open-angle glaucoma (POAG) and in nonglaucomatous patients. METHODS: The main outcomes of this prospective study were percent and absolute IOP change, which were calculated using the preoperative IOP and the IOP 4 months after cataract surgery in POAG and nonglaucomatous eyes. Lens position (LP), defined as anterior chamber depth (ACD) + one-half lens thickness (LT), was assessed preoperatively using parameters from optical biometry...

PURPOSE: To evaluate the safety and efficacy of phacoemulsification for management of post-filtering ocular hypotony. METHODS: This prospective interventional case series study recruited 21 consecutive patients with an established diagnosis of ocular hypotony with or without maculopathy. Clear corneal incision phacoemulsification was done for all patients. Nineteen cases that completed a follow-up of at least 6 months were considered for final analysis. RESULTS: Mean baseline intraocular pressure (IOP) was 2...

PURPOSE: To compare choroidal thickness (CT) and retinal thickness (RT) between eyes with proliferative diabetic retinopathy treated with panretinal photocoagulation (PRP) or PRP with intravitreal bevacizumab (PRP + IVB). METHODS: Thirty-three patients with proliferative diabetic retinopathy were randomized to have one eye treated with PRP and the other with PRP + IVB. Change in CT was compared with baseline using enhanced depth imaging-optical coherence tomography at baseline and Months 1, 3, 6, and 10 after treatment...

BACKGROUND: Loss of retinal ganglion cell-inner plexiform layer (GCIPL) thickness has been shown in different optic neuropathies. In this study, we evaluated the capability of GCIPL analysis by optical coherence tomography (OCT) to detect early neuronal loss during the time course of nonarteritic anterior ischemic optic neuropathy (NAION). METHODS: Twenty-four patients with unilateral NAION participated in this prospective, comparative study. Affected and unaffected eyes underwent spectral domain OCT measurement of the retinal nerve fiber layer (RNFL), total macula, and GCIPL thicknesses...

PURPOSE: The purpose of this study is to compare anterior segment-optical coherence tomography (AS-OCT) parameters in phacomorphic angle closure and acute primary angle closure (APAC) eyes. METHODS: In this cross-sectional case series, a total of 134 patients with phacomorphic angle closure (28 eyes) or APAC (54 eyes), as well as normal control subjects (52 eyes), were enrolled. Patients underwent AS-OCT imaging and A-scan biometry of both eyes. Anterior chamber depth (ACD), anterior chamber area (ACA), iris thickness (IT), iris curvature, lens vault (LV), anterior vault (AV), and angle parameters including angle opening distance (AOD 500 and AOD750) and trabecular iris space area (TISA500 and TISA750) were measured in qualified images using the Zhongshan Angle Assessment Program and compared among eyes with phacomorphic angle closure, APAC, and normal control subjects...
