PURPOSE: Klotho is a newly discovered protein that presumably has an important role in the aging process. The goal of this research is to compare the levels of Klotho and Endothelin-1 (ET-1) in the serum and aqueous humor of patients with pseudoexfoliation syndrome (PES) and pseudoexfoliative glaucoma (PEG). PATIENTS AND METHODS: Aqueous humor and serum samples were obtained at the time of cataract surgery from 15 patients with PES, 15 patients with PEG, and 15 control patients...

PURPOSE: To investigate the genetic association of lysyl oxidase-like 1 (LOXL1) gene polymorphisms in patients with pseudoexfoliation (PEX) syndrome and PEX glaucoma of Turkish descent. METHODS: Three LOXL1 single nucleotide polymorphisms (SNPs) (rs1048661, rs3825942, and rs2165241) were analyzed in 109 Turkish patients (44 patients with PEX syndrome, 65 patients with PEX glaucoma) and 47 healthy subjects. RESULTS: "A" allele of SNP rs3825942 was underrepresented in control group compared with the glaucoma [odds ratio (OR)=4...

INTRODUCTION: Corneal endothelial damage following phacoemulsification is still one of the major concerns of modern day cataract surgery. Although many techniques have been proposed, the risks of posterior capsular rupture and corneal endothelium damage persist. In theory, damage to the corneal endothelium is minimised by delivering the lowest phaco energy only in the direction necessary to emulsify the lens nucleus. Hence, it is believed that the bevel of the needle should be turned towards the nucleus or the nuclear fragment (ie, bevel-down...

PURPOSE: The aim of this study was to investigate the factors associated with decreases in corneal endothelial cell density (ECD) resulting from cataract surgery in eyes with pseudoexfoliation syndrome (PEX). METHODS: The clinical records of 78 eyes of 78 patients with PEX who had undergone cataract surgery were reviewed. ECD was measured preoperatively and at 3 months postoperatively with specular microscopy. Multiple regression analysis was used to assess the factors that were significantly related to the rate of ECD loss...

OBJECTIVES: To study the predisposition factors for dislocation of the intraocular lens (IOL)-capsular bag complex and analyze the results of subsequent reimplantation surgery. METHODS: The exclusion criteria were complicated cataract surgery and minor dislocations that appeared in the first year after cataract surgery. Thirty-six months of monitoring of the reimplantation surgery was required. The primary measurements of results were factors concerning dislocation, the interval between cataract surgery and dislocation, and postoperative complications...

PURPOSE OF THE STUDY: The purpose of the study was to determine whether there are different patterns of retinal nerve fiber layer (RNFL) thinning as measured by spectral domain optical coherence tomography (SD-OCT) for 4 subtypes of open angle glaucoma (OAG): primary OAG (POAG), normal tension glaucoma (NTG), pseudoexfoliation glaucoma (PXG), and pigmentary glaucoma (PDG) and to compare them with normal controls. MATERIALS AND METHODS: SD-OCT RNFL thickness values were measured for 4 quadrants and for 4 sectors (ie, superior-nasal, superior-temporal, inferior-nasal, and inferior-temporal)...

AIM: To establish the role of nitric oxide (NO), ascorbic acid and tumour necrosis factor-α (TNF-α) in the pathogenesis of pseudoexfoliation glaucoma (XFG). METHODS: Our study included 120 patients who were referred for cataract surgery. All patients were divided into four groups according to clinical findings: XFG, early and late pseudoexfoliation syndrome (XFS), and cataract (without pseudoexfoliation). Serum and aqueous humour levels of the ascorbic acid, NO and TNF-α were measured...

AIM: To evaluate the possible relationship of optic disc area with retina nerve fiber layer in different glaucoma subtypes. METHODS: One eye each was chosen from 45 patients with ocular hypertension, 45 patients with primary open angle glaucoma, 45 patients with pseudoexfoliation glaucoma and 45 healthy controls followed in our hospital. The records of the patients were reviewed retrospectively. Optic disc area and circumpapillary retina nerve fiber layer measurements were obtained using optical coherence tomography...

BACKGROUND: Reports of central corneal thickness (CCT) among glaucoma patients, particularly for pseudoexfoliative glaucoma (PXG) and Primary Angle Closure Glaucoma (PACG) are scarce in the Sub-Saharan African (SSA) population. The aim of this study is to evaluate CCT in black patients with newly diagnosed glaucoma and ocular hypertension (OHT) in South West Ethiopia. METHODS: This was a prospective study undertaken with an ultrasonic pachymeter from June 2014 to February 2015 in Jimma University Specialized Hospital...

PURPOSE: To evaluate the impact of pseudoexfoliation syndrome on intraocular lens (IOL) dislocation after phacoemulsification cataract surgery and explore possible associations related to surgical technique. METHODS: We systematically searched the MEDLINE, Embase, Web of Science, Cochrane, and Lilacs databases and grey literature sources and identified (on March 1, 2016) 14 cohort and case-control studies comparing IOL dislocation in patients with and without pseudoexfoliation syndrome who had undergone phacoemulsification...

We report a case of an explanted stainless steel miniature glaucoma drainage device (EX-PRESS) implanted under a scleral flap for pseudoexfoliation open-angle glaucoma surgical treatment. The glaucoma shunt was implanted in a 75-year-old white man with medically refractive glaucoma. Cataract surgery was performed simultaneously. After 2 years, the shunt extruded through the scleral flap and the conjunctiva and it was, therefore, explanted. Scanning electron microscopy images of the EX-PRESS mini glaucoma shunt were acquired to verify the patency of the device lumen and the presence of fibrosis or cellular adhesion on the device...

PURPOSE: To evaluate the corneal clarity quantitatively by using corneal densitometry in patients with pseudoexfoliation syndrome (PES) and to compare the results with those of healthy control subjects. MATERIALS AND METHODS: Corneal densitometry measurement of patients with bilateral PES and healthy control subjects was carried out by Scheimpflug corneal topography (PentacamHR). For densitometry analysis, the 12-mm diameter area of the cornea was subdivided into 4 concentric radial zones (0 to 2, 2 to 6, 6 to 10, 10 to 12 mm) and also into anterior, central, and posterior layers based on corneal depth...

PURPOSE: Uncontrolled intraocular pressure (IOP) after glaucoma filtration surgery is a challenging problem in the management of glaucoma patients. The Trabectome is a device for selective electroablation of the trabecular meshwork through a clear cornea incision without affecting the conjunctiva. Minimally invasive glaucoma surgery using the Trabectome is safe and effective as primary glaucoma surgery. Here we investigate the results of ab interno trabeculectomy with the Trabectome for IOP control in patients with a failed filtering bleb...
