Abstract This study was conducted to investigate the size and shape of foveal avascular zone (FAZ) determined by optical coherence tomography angiography (OCTA) relationship clinical findings in normal subjects. a cross-sectional with seventy eyes 70 volunteers. The superficial FAZs were assessed its area, length perimeter, Feret’s diameter, circularity, axial ratio, roundness, solidity. correlations between each parameter statistically determined. coefficients variation (CV) parameters FAZ...
We evaluated the effect of intravitreal triamcinolone acetonide (IVTA) or bevacizumab (IVB) on subfoveal choroidal thickness (SFCT) in eyes with diabetic macular edema (DME).In this prospective, randomized, interventional comparative study, 51 DME patients were randomized to receive either IVTA IVB. The central (CMT) and SFCT determined by optical coherence tomography at 24 hours, 7 days, 4, 8, 12 weeks. 1500 3000 μm nasal temporal fovea also was measured. values obtained before compared...
Abstract This study was performed to compare the area of foveal avascular zone (FAZ-area) obtained by three optical coherence tomography angiography (OCTA) instruments. a cross-sectional, non-interventional twenty-seven healthy right eyes. The superficial and deep FAZ-area measured manually with OCTA instruments: Triton (Topcon), RS3000 (Nidek), CIRRUS (Zeiss). intra-rater, inter-rater, inter-instrument correlation coefficients (CC) were assessed. intra-rater inter-rater CC significantly...
Abstract This study was to investigate the choroidal vessels in eyes with central serous chorioretinopathy (CSC) quantitatively. We studied 41 CSC and their fellow eyes, normal of age-adjusted individuals. En-face optical coherence tomography image top 25% slab Haller’s layer analyze. The mean vessel area, length, diameter were calculated. running pattern quantified used determine degree symmetry, “symmetry index”. area not significantly different from that but larger than eyes. length...
Purpose.: To determine the symmetry of retinal thicknesses (RT) between 32 pairs superior and inferior sectors by posterior pole asymmetrical analysis (PPAA) spectral-domain optical coherence tomographic (SD-OCT) images in healthy eyes. In addition, to their association with position peak nerve fiber layer (RNFL) thickness.
Abstract This study was to investigate the relationship between metamorphopsia and foveal avascular zone (FAZ) parameter in eyes with epiratinal membrane (ERM). We studied patients an ERM visited retinal service unit at Kagoshima University Hospital or Shirai Hospital. The best-corrected visual acuity (BCVA), degree of by M -CHARTS™ were evaluated. 3 × mm optical coherence tomography angiography (OCTA) images superficial layer obtained. Area (mm 2 ), circularity, eigen value calculated using...
Purpose: To compare the submacular to perimacular choroidal structure in images obtained by wide-field optical coherence tomography (OCT). Methods: Thirty eyes of 30 healthy volunteers (15 men) were studied. Twelve radial circumferential scans recorded with enhanced depth imaging OCT from macular and zones. The sizes luminal stromal areas choroid determined. two zones subdivided into superior, inferior, nasal, temporal sectors. total area, areas, ratio each sector compared. Results: All...
To compare the ability of ocular fundus images obtained by Spectralis MultiColor scanning laser ophthalmoscope (MC-SLO) to that conventional color (CF) in detecting non-glaucomatous nerve fiber layer defects (NFLDs). A cross-sectional, retrospective study. Patients with retinal diseases who had examination both MC-SLO and CF instruments at Kagoshima University from December 2016 February 2017 were studied. Eyes NFLDs optic discs analyzed. The visibility was classified into three grades:...
Purpose: To assess the ability of multicolor scanning laser ophthalmoscope (MC-SLO) to screen for epiretinal membranes (ERMs). Methods: A retrospective cross-sectional study 35 eyes 32 patients with an ERM detected by optical coherence tomography and 46 23 healthy volunteers. The detection was graded into three visibility scores—1, not visible, 2, barely 3, clearly visible—by retina specialists or ophthalmology residents. sensitivity specificity merged image MC-SLO color fundus photographs...
Abstract Background To investigate the relationship between changes in optic disc size and color, cup-to-disc (C/D) ratio, axial elongation schoolchildren. Methods A prospective cohort study was performed 75 right eyes of elementary school students for six years (from 8.5 to 14.5 old). In first last year, all participants underwent optical length measurement color fundus photography. The calculated by dividing intensity red sum red, green, blue. area modifying number pixels according...
Abstract The purpose of this study was to compare the incidences macular irregularities elementary school (ES) and junior high (JHS) students. This a prospective cross-sectional observational 122 right eyes ES students (8–9 years) 173 JHS (12–13 years). Vertical images macula were obtained by optical coherence tomography. classified based on vertical symmetry posterior pole, then sub-classified as convex-, flat-, concave-, or dome-shaped direction curvature retinal pigment epithelium. One...
Purpose: To quantify the vessels of Haller's layer normal subjects in en-face optical coherence tomographic images. Methods: One hundred and seventy-two eyes were studied. En-face images top 25% slab was analyzed. The vessel area, length, mean diameter calculated. running pattern quantified for degree symmetry designated as “symmetry index.” coefficient correlation between each choroidal parameter age, sex, axial central thickness determined. Results: area 23.4 ± 3.6 mm 2 , length 164.6 24.1...
Abnormalities of the running pattern choroidal vessel have been reported in eyes with pachychoroid diseases. However, it is difficult for clinicians to judge high reproducibility. Thus, purpose this study was compare degree concordance vessels between that determined by artificial intelligence (AI) experienced clinicians.The en face images Haller's layer 413 normal and diseased classified as symmetrical or asymmetrical human raters three supervised machine learning models; support vector...
Purpose: To determine the relationship between morphological parameters of foveal avascular zone (FAZ) in optical coherence tomography angiographic (OCTA) images and best-corrected visual acuity (BCVA) branch retinal vein occlusion (BRVO). Methods: This was a retrospective cross-sectional study. Eyes with BRVO without apparent macular edema were studied. The superficial FAZ 3 × mm OCTA delineated manually. size shape, circularity axial ratio, determined, values compared to that controls....
Purpose To investigate retinal vessel shift (RVS) and its association with axial length (AL) elongation in junior high school students. Methods Total 161 eyes of healthy students were prospectively studied. Optical AL anterior chamber depth (ACD) measurements, fundus photography performed the first third grades. Eyes subjects grade that had perfect matching among all vessels allocated to RVS(−) group, otherwise RVS(+) group. In peripapillary arteries angle (PRAA) was measured for...
To determine the relationship between ocular biometrics and axial length (AL) elongation its rate in elementary school children.This is a prospective observational study of 102 right eyes third-grade students who were 8 to 9 years old. All participants underwent measurements AL, anterior chamber depth (ACD), lens thickness (LT) annually for 3 years. The AL during first half second was calculated by subtracting 1st year from that at 2nd year, 3rd minus year. total (TALE) obtained summing up...
