Purpose.: To identify sex-related differences and age-related changes in individual retinal layer thicknesses a population of healthy eyes across the lifespan, using spectral domain optical coherence tomography (SD-OCT). Methods.: In seven institutes Japan, mean nerve fiber (RNFL), ganglion cell (GCL), inner plexiform (IPL), nuclear (INL), outer (OPL), (ONL), photoreceptor segment (IS), (OS) were measured SD-OCT with new automated segmentation protocol 256 subjects. Results.: Interoperator...
To clarify the role of choroidal vascular abnormalities in central serous chorioretinopathy (CSC) active stage, remission, and recurrence.Indocyanine green angiography fluorescein were performed 105 eyes (104 patients) with CSC. Forty-six patients followed up for 6 to 48 months (mean +/- standard deviation, 22.5 8.9 months) repeated 3.5 1.5 times). Indocyanine also during remission all 46 CSC recurrent eyes. Unaffected fellow underwent angiographic examinations patients.In CSC, indocyanine...
Dendritic spines have two major structural elements: postsynaptic densities (PSDs) and actin cytoskeletons. PSD proteins are proposed to regulate spine morphogenesis. However, other molecular mechanisms should govern morphogenesis, because the initiation of morphogenesis precedes synaptic clustering these proteins. Here, we show that drebrin, an actin-binding protein highly enriched in dendritic spines, governs We immunocytochemically analyzed developing hippocampal neurons low-density...
The purpose of this study was to investigate the correlation between best-corrected visual acuity and foveal microstructural changes external limiting membrane junction inner outer segments photoreceptors in diabetic macular edema.The authors performed spectral-domain optical coherence tomography all eyes. defined central subfield thickness as average retinal 1-mm scanned area. length disruption fovea (1.8 mm diameter) were measured graded according their follows: 1) >1.4 mm; 2) >0.4 but...
In Brief Purpose: To identify the tomographic features of branching vascular networks in patients with polypoidal choroidal vasculopathy (PCV). Methods: We prospectively performed third-generation optical coherence tomography (OCT) and fluorescein angiography for 44 eyes 42 (mean age ± SD, 67.1 9.1 years) PCV. All had lesions that were confirmed by indocyanine green angiography. Results: OCT showed double reflective layers consisted retinal pigment epithelium (RPE) another highly layer...
Abstract Superior and inferior macular vortex veins are divided by a horizontal watershed passing through the macula. We evaluated vein remodeling in eyes with pachychoroid neovasculopathy (PNV). Thirty of 30 patients treatment-naïve PNV normal age-, gender-, refraction-matched subjects were studied. assessed features employing en face optical coherence tomography (OCT) determined central choroidal thickness (CCT) using B-mode OCT. Of eyes, was identified 24 (80%), while venous anastomosis...
<h3>Objective</h3> To describe a noninvasive method to visualize choroidal circulation by means of erythrocytic velocity. <h3>Methods</h3> Laser speckle flowgraphy (LSFG) and indocyanine green (ICG) angiography were performed on 9 volunteers. The LSFG measures the quantitative relative velocity index erythrocytes (normalized blur [NB] value) in retinal vessels. We averaged NB values from 3 pulsations made composite 1.5-mm-square maps during 1 pulsation. By overlapping 5 adjacent maps, we...
Purpose.: To demonstrate the three-dimensional macular thickness distribution in normal subjects by spectral domain optical coherence tomography (SD-OCT) and evaluate its association with sex, age, axial length. Methods.: Mean regional retinal measurements on Early Treatment Diabetic Retinopathy Study (ETDRS) layout were obtained raster scanning (6 × 6 mm) using SD-OCT 248 eyes of Japanese subjects. Results.: foveal was 222 ± 19 μm; it significantly greater men (226 μm) than women (218 18 P...
The outer plexiform layer (OPL) includes the photoreceptor synapse and Henle fiber (HFL) in macular area. We attempted to improve optical coherence tomography imaging of HFL by changing angle measurement beam.Thirteen normal eyes underwent spectral domain tomography. To focus beam perpendicular obliquely oriented HFL, system was aimed at periphery pupil.The cross-sectional image area inclined right or left if entered from pupil. reflectivity OPL increased because strong backscattering light...
