In Brief Purpose: To compare choroidal thicknesses among eyes with early age-related maculopathy (ARM), neovascular macular degeneration, polypoidal vasculopathy, and central serous chorioretinopathy. Methods: Patients (37 eyes), degeneration (24 vasculopathy (12 chorioretinopathy (31 eyes) underwent spectral-domain optical coherence tomography evaluations using a choroid scanning protocol. A horizontal linear section comprising 50 averaged scans was obtained of each macula. The thickness...
Purpose.: To evaluate photoreceptor inner/outer segment (IS/OS) defect parameters by using spectral domain-optical coherence tomography (SD-OCT) for correlation with visual outcomes in macular hole surgery (MHS). Methods.: This study was an interventional, retrospective case series. Twenty-three eyes (23 patients) were examined SD-OCT before and after (median, 2.3 months) anatomically successful MHS. Two formats of OCT analyzed: linear (raster) composite (partial fundus image). Factors that...
Purpose: To determine the relationship between aqueous concentrations of inflammatory and angiogenic factors severity diabetic retinopathy macular edema.Methods: Aqueous samples were obtained from 50 eyes patients 28 nondiabetic subjects. The levels factors, including IL-1β, TNF-α, MCP-1, IP-10, IL-8, IL-6, VEGF measured with multiplex bead array assays. cytokines investigated according to edema by optical coherence tomography.Results: higher in than MCP-1 IP-10 elevated severe NPDR PDR...
To identify the clinical features, treatment outcomes, and prognostic factors of endogenous endophthalmitis in multiple tertiary referral centers South Korea over a 6-year period.The authors conducted retrospective review medical records 57 eyes 43 patients diagnosed with from January 2005 to December 2011, which was referred centers.Fifty-seven cases were followed for mean 18.7 months (range, 0.5-50 months). The common underlying diseases diabetes mellitus (46.5%) liver cirrhosis (20.93%)....
To investigate systemic factors associated with central serous chorioretinopathy (CSC).We retrospectively reviewed the medical records of 113 Korean patients who were diagnosed CSC and underwent history taking a specialized questionnaire for CSC. They matched age gender at ratio 1 : 3 to 339 normal controls. Normal controls consecutively selected from database Health Promotion Center. General characteristics histories compared between two groups. The statistical analyses used included...
Abstract We sought to compare the retinal thickness measurements collected using different optical coherence tomography (OCT) devices. This prospective study included 21 healthy cases, and was measured PLEX Elite (Carl Zeiss Meditec, Dublin, California, USA), DRI OCT-1 Atlantis (Topcon Corp, Tokyo, Japan), Cirrus 5000 HD-OCT Meditec), Spectralis OCT (Heidelberg Engineering, Heidelberg, Germany), respectively. The mean central (CRT) of Early Treatment Diabetic Retinopathy Study (ETDRS) area...
Purpose: To investigate variations in chorioretinal vasculatures fellow eyes of patients with unilateral neovascular age-related macular degeneration (nAMD). Methods: We included consecutive nAMD from swept source optical coherence tomography (SS-OCT) angiography database. Vascular and nonvascular indices were determined based on SS-OCT images. Variation the vascular or index was compared between without early AMD. Results: In 146 eyes, 88 (60.3%) had AMD 58 (39.7%) a normal fundus. density...
To quantify vascular and structural macular variables in healthy eyes to investigate correlations between these age using optical coherence tomography angiography.A total of 261 subjects with normal fundus were included. Central thickness, ganglion cell layer inner plexiform outer retina subfoveal choroidal vascularity index measured tomography. Foveal avascular zone area, density, flow void area angiography.Vascular density the superficial capillary plexus was correlated central thickness...
<i>Purpose:</i> To report a case of complete regression choroidal metastasis secondary to non-small-cell lung cancer (NSCLC). <i>Methods:</i> Retrospective review female patient treated with intravitreal bevacizumab and oral erlotinib combination therapy for metastases NSCLC. Best corrected visual acuity (BCVA), fluorescein angiography (FA), optical coherence tomography (OCT), B-scan ultrasonography were compared during the 4-month treatment period....
Retinal pigment epithelial tears may occur after photodynamic therapy (PDT) in various diseases. The authors report a case of retinal tear half light intensity (300 mW/cm2) PDT large serous detachment associated with chronic atypical central chorioretinopathy. A 52-year-old woman chorioretinopathy the left eye received her first treatment using verteporfin spot size 6,640 microm, duration 83 seconds, and standard 600 mW/cm2 intensity, where delivered dose was only 25 J/cm2. Two weeks later,...
Abstract The objective of this study was to investigate the relationship between suspended scattering particles in motion (SSPiM) optical coherence tomography angiography (OCTA) and treatment response diabetic macular edema (DME). We retrospectively reviewed medical records patients diagnosed with DME who had undergone intravitreal injection. density ratio (ODR) intraretinal cyst numbers hyperreflective foci from OCT images SSPiM OCTA were compared, their association analyzed. Forty-five...
To compare the short-term effects of intravitreal versus posterior subtenon injection triamcinolone acetonide for diabetic macular edema.This is a prospective and interventional study. Sixty eyes 60 patients who had diffuse edema were assigned to receive single (4 mg) or (40 acetonide. The central retinal thickness was measured using optical coherent tomography before at 1 3 months after injection. Visual acuity intraocular pressure (IOP) also measured.Both injections resulted in significant...
<h3>Aims</h3> To find the explanatory parameters for best corrected visual acuity (BCVA) and microperimetry (MP) in resolved central serous chorioretinopathy. <h3>Methods</h3> Thirty-three eyes from 33 patients were analysed retrospectively. BCVA MP correlated with various functional morphological tests. The mean sensitivities at fovea 2° 4°, retinal thickness degree of defect photoreceptor inner outer segment junction (IS/OS) spectral domain-optical coherent tomography image, normalised...
Purpose: The purpose of this study was to investigate the relationship between ocular perfusion pressure (OPP) and subfoveal choroidal thickness (CT) in eyes with early age-related macular degeneration (AMD) or without reticular pseudodrusen (RPD). Methods: We evaluated clinical history, blood parameters, fundus photography, optical coherence tomography images consecutive patients AMD. calculated mean OPP from intraocular pressure. Results: included 103 patients, classifying 45 as RPD group...
