Alert. Association between systemic hypertension and macular thickness measured by optical coherence tomography. Filter the specific keyword. In these patients, the central foveal thickness was 172±35 μm in the 49 eyes without macular edema as assessed by slit-lamp biomicroscopy, and 339±101 μm in the 23 eyes with macular edema. Optical coherence tomography (OCT) was used to assess global RNFL thickness, central macular thickness, and GCL thickness in both eyes. Objective: To evaluate optical coherence tomography, a new technique for high-resolution cross-sectional imaging of the retina, for quantitative assessment of retinal thickness in patients with macular edema. Since the normative value of the retinal macular thickness is undocumented in the Middle East, the aim of this work is to assess the normative values of the macular thickness in healthy eyes in a Middle Eastern population and its relationship with age, sex, and laterality. suggested that the choroidal volume assessment is advantageous due to the irregularities of the border between the choroidal and sclera . qualitative and quantitative assessment of the macula and peripapillar RNFL . Listing a study does not mean it has been evaluated by the U.S. Federal Government. Conclusions. . The purpose of this study was to compare the optic disc parameters, retinal nerve fiber (RNFL), and macular ganglion cell layers between patients with diabetes mellitus (DM) type 2 and healthy controls.In this cross-sectional study, 69 eyes of 69 diabetic patients without diabetic retinopathy and 47 eyes of 47 healthy controls were included. Outer temporal macular thickness had a statistically significant difference (SD: 5.12 µm, 95%CI: 2.24-7.99, p < 0.001), being thinner in the study sample compared with normal cut-off values. The superior and nasal quadrants were thickest overall. Mean ± SD values were 166 ± 15 μm for the foveal minimum, 204 ± 19 μm for the central macula (A1) and 7.11 ± 0.35 mm 3 for macular volume. The total macular volume was 7.4 in both eyes. Statistical analysis SPSS 22.0 software was used to analyze the data. A newer application of OCT involves macular imaging to assess for glaucoma.

Purpose To investigate the relationship of macular intercapillary area (ICA) with macular ganglion cell-inner plexiform layer (GCIPL) thickness and central visual field sensitivity (CVFS) in normal tension glaucoma (NTG). The measurement was performed in the fovea region by measuring the distance between the rear edge of the RPE and a perpendicular line to the choroid-sclera junction (Fig. Methods It was a prospective, single-center study. The average macular thickness was 263.4 μm for the right eye and 263.7 μm for the left eye. Central macular thickness was highly correlated with logarithmic converted visual acuity in diabetic macular oedema. To compare outer retinal layer (ORL) thickness and photoreceptor outer segment (PROS) length between normal eyes and eyes with diabetic macular edema (DME), and also, to study the correlation between central macular thicknesses (CMT), ORL, and PROS length with best corrected visual acuity (BCVA) in DME. A simplified severity scale for age-related macular degeneration: AREDS Report No. The temporal quadrant was thinner than the nasal quadrant. Overall macular thickness, asymmetry between the eyes and progression over time, can be used as a metric for glaucoma diagnosis. The mean central macular thickness was found to be 266.2 ± 22.7 µm. 2016 Mar;95(10):e2967. 1174 - 1180 Abstract Read online Background: Some studies showed that strabismus surgery is associated with possible damage to macula.

Assessment of Macular Choroidal Thickness by Optical Coherence Tomography and Angiographic Changes in Central Serous Chorioretinopathy April 2012 Ophthalmology 119(8):1666-78 18", Arch Ophthalmol. The macular thickness was measured using the MM6 (macular mapping at 6 mm) program. Central foveal thickness was also manually determined as 170 ± 18 μm, approximately 12 μm less than the value . As expected, macular thickness was thinnest at the center, thickest within 3-mm diameter of the center, and diminished toward the periphery of the macula. Purpose To evaluate clinical outcome after surgery of idiopathic epiretinal membranes (ERM) with internal limiting membrane (ILM) peeling using a commercial combination of Brilliant blue G (BBG, 0.25 mg/ml) with 4% polyethylene glycol (PEG). Ophthalmology. Legarreta et al. Using this instrument we illustrate for the first time the application of en-face OCT imaging to produce topography and perform area and volume measurements of the optic nerve. Margolis R, Spaide RF. A sex ratio was 1.01. Independent T-tests and analyses of variance (ANOVAs) were used to compare the mean CST, MT, and MV in individuals grouped by sex and age. All patients underwent a complete ophthalmologic examination, as well as visual field (VF) testing, and the measurement of macular and GCC thickness with SD-OCT.

Summary, Overview and Review of Sentence Examples. Evaluation of asymmetry in hemifield macular thickness may serve as an assessment tool in the early diagnosis of glaucoma. 2005;123:1570-1574. To compare peripapillary and macular choroidal thickness (PCT and MCT) between open-angle glaucoma (OAG) and normal controls using swept-source optical coherence tomography (SS-OCT), and to evaluate global and localized relationships between choroidal thickness and various factors in OAG, also using SS-OCT.In this cross-sectional comparative study, 134 OAG patients and 73 normal controls were . A special imaging instrument was developed which can acquire optical coherence tomography (OCT) en-face images from the eye fundus, and simultaneously a confocal image. Ophthalmology.

Choroidal thickness in polypoidal choroidal vasculopathy and exudative age-related macular degeneration. Chung SE, Kang SW, Lee JH, et al. The central macular thickness was 174.1 μm for the right eye and 173.3 μm for the left eye. 2005;123:1570-1574. 13 Historically, the WASBT was used for evaluation of macular disease. A fast macular thickness protocol consisting of a 6-mm radial scan centered on the fovea was used for the analysis, and the data were analyzed using the t-test for independence and linear regression. (2) To establish correlations between the thickness of the central choroid (BM-CSI) in the LHM and the parameters of best-corrected visual acuity and reading vision in patients with LMH. View 1 excerpt, references methods; Save. Methods This cross-sectional study examined 73 glaucoma patients and 19 normal subjects. The retinal thickness/volume tabular protocol was selected as the analysis protocol, and the calculation of macular thickness was based on the 6 mm fast macular thickness map analysis printout. Assessment of macular thickness changes by OCT in asymptomatic subjects at high genetic risk of developing Alzheimer's disease. Arcuate patterns of RNFL loss may also be seen extending from the macula toward the ONH. Assessment of macular thickness is important in the evaluation of various eye diseases.
