BACKGROUND To investigate the reproducibility of macular ganglion cell-inner plexiform layer (GCIPL) thickness measurement in normal eyes determined by different operators and two different raster scanning protocols of Cirrus high-definition optical coherence tomography (HD-OCT). METHODS One hundred and two eyes of 102 normal subjects were scanned three times using Cirrus HD-OCT with Macular ...

BACKGROUND It is unclear how retinal ischemia influences the changes of visual acuity, macular sensitivity, macular thickness, and macular volume after the performance of pars plana vitrectomy (PPV) for macular edema in patients with central retinal vein occlusion (CRVO). METHODS Ten patients (10 eyes) with CRVO and macular edema underwent PPV. Retinal ischemia was evaluated from the area of ...

purpose: to determine if intravitreal injection of triamcinolone acetonide is safe and effective in the treatment of diabetic macular edema unresponsive to prior laser photocoagulation. methods: fifty-four eyes of 38 patients with clinically significant macular edema which had received at least two sessions of laser photocoagulation according to early treatment diabetic retinopathy study guidel...

Objective: Remote Ischemic Preconditioning (RIPC) as the transient ischemia and reperfusion of the arm is a promising method for protecting different tissue from future ischemia. These effects might be mediated through vascular and endothelial growth factor (VEGF) pathway. We investigated the influence of RIPC on diabetic macular edema (DME) as a chronic ischemic condition in patients who were ...

Purpose. The aim of this study is to examine the influence of capsulotomy size on, spherical equivalent (SE), intraocular pressure (IOP), and macular thickness. Materials and Methods. Sixty-eight patients were examined preoperatively and 1, 4, and 12 weeks after Nd:YAG capsulotomy. Patients were divided into two groups based on the postoperative capsulotomy size. Changes in SE, IOP, and macular...

BACKGROUND The aim of this study was to compare the efficacy of spectral-domain optical coherence tomography (SD-OCT) and fluorescein angiography (FA) in the guidance of macular laser photocoagulation for diabetic macular edema. METHODS This was a prospective interventional clinical comparative pilot study. Forty eyes from 24 consecutive patients with diabetic macular edema were allocated to ...

PURPOSE To compare macular thickness in children with functional amblyopia and those without amblyopia using optical coherence tomography (OCT). METHODS This case-control study was conducted on 93 children aged 3-10 years including 44 cases with unilateral amblyopia and 49 subjects without amblyopia. Amblyopic eyes were considered as the case group and their fellow eyes as internal controls; ...

SD-OCT has become an essential tool for evaluating macular pathology; however several aspects of data collection and analysis affect the accuracy of retinal thickness measurements. Here we evaluated sampling density, scan centering, and axial length compensation as factors affecting the accuracy of macular thickness maps. Forty-three patients with various retinal pathologies and 113 normal subj...

PURPOSE To estimate genetic influences accounting for macular thickness in the Korean population. METHODS Study subjects were 830 healthy Korean adults (117 monozygotic twin pairs and 523 family members) from the Healthy Twin study. Macular thickness was measured with optical coherence tomography for nine subfields including the fovea, four inner quadrants (within 1 to 3 mm of the center), an...

OBJECTIVE To determine the pattern of functional and anatomical responses after intravitreal triamcinolone (IVTA) for macular edema in diabetic retinopathy, retinal vein occlusion, uveitis, and macular telangiectasia. MATERIAL AND METHOD A Retrospective interventional study was carried out between January 2004 and July 2006. Thirty-eight eyes from 36 patients who had undergone an IVTA injecti...
