PURPOSE To characterize central corneal thickness (CCT) in Latinos aged 40 or more years. METHODS A population-based cohort of Latinos from two census tracts in La Puente, California, underwent measurements of CCT and intraocular pressure (IOP). CCT was measured with an ultrasonic pachymeter, and IOP was measured by applanation tonometry. One eye of each of 1699 participants was included in t...

purpose: to evaluate the influence of different confounding factors on the effect of intravitreal triamcinolone acetonide injection for refractory diabetic macular edema. methods: in a prospective placebo-controlled randomized clinical trial, 88 eyes with refractory diabetic macular edema were randomly assigned into two groups including 45 in the treatment group (4 mg intravitreal triamcinolone...

PURPOSE To report the frequency of optical coherence tomography (OCT) scan artifacts and to compare macular thickness measurements, interscan reproducibility, and interdevice agreeability across 3 spectral-domain (SD) OCT (also known as Fourier domain; Cirrus HD-OCT, RTVue-100, and Topcon 3D-OCT 1000) devices and 1 time-domain (TD) OCT (Stratus OCT) device. DESIGN Prospective, noncomparative,...

Retinal and intra-retinal layer thicknesses are routinely generated from optical coherence tomography (OCT) images, but on-board software capabilities and image scaling assumptions are not consistent across devices. This study evaluates the device-independent Iowa Reference Algorithms (Iowa Institute for Biomedical Imaging) for automated intra-retinal layer segmentation and image scaling for th...

purpose: to determine the distribution of intraocular pressure (iop), central corneal thickness (cct), and vertical cup-to-disc ratio (vcdr) in a healthy iranian population. methods: this cross-sectional, epidemiologic study (yazd eye study, yes) was performed on iranian adults, aged 40 to 80 years, residing in yazd, iran between 2010 and 2011. eligible subjects were selected using cluster rand...

PURPOSE To evaluate changes in the multifocal electroretinogram (mfERG) in patients with neovascular age-related macular degeneration (nAMD) undergoing ranibizumab treatment. METHODS This was an observational, longitudinal, prospective study. Treatment-naive patients with nAMD who met the inclusion and exclusion criteria underwent a course of monthly injections of ranibizumab over 3 months. A...

PURPOSE The purpose of this study was to determine whether eyes with center-involved diabetic macular edema, treated with focal/grid photocoagulation, in which there is a reduction in central subfield thickness (CST) measured with optical coherence tomography after 16 weeks, will continue to improve if retreatment is deferred. METHODS This is a prospective, multicenter, observational, single-...

Abstract Purpose To evaluate the effectiveness of subthreshold micropulse laser as compared to intravitreal injection ranibizumab in treatment center involving diabetic macular oedema. Methods A total 76 eyes 62 patients with oedema were divided into two groups. Group received while group B rescue ranibizumab. The change from baseline best correscted visual acuity and central subfield thickness...
