“…There was no correlation between the visual acuity and retinal thickness in any treatment group [17,20]. A similar association was found by Massin et al, who analyzed the postoperative visual acuity against retinal thickness changes in patients with ERM [21].…”

Purpose: To determine the influence of peeling the internal limiting membrane (ILM) on visual acuity, M-Charts, visual field and OCT in patients with retinal detachment. Methods:We have analyzed 63 patients in three groups. The first group (group B) consisted of 26 patients who underwent vitrectomy with ILM peeling performed after staining with Brilliant Peel. The second group (group G) consisted of 23 patients, in whom ILM peeling was performed after staining with indocyanine green. The third group (group Z) consisted of 14 patients in whom ILM peeling had not been performed. Ocular examination involved the assessment of visual acuity for distance and near vision, visual field testing, metamorphopsia quantification, dilated fundus exam and OCT.Results: There was a statistically significant improvement in the postoperative best corrected visual acuity for distance vision in groups B (p=0.00007), G (p=0.0002) and Z (p=0.003). There were statistically significant differences in the prevalence of ellipsoid layer photoreceptors abnormalities between the groups (p=0.004), with more abnormalities in group Z (64%) as compared to groups B (20%) and G (17%). Statistical analysis also revealed significant differences in the epiretinal membrane (ERM) incidence between the three groups (p=0.02), with ERM occurring more frequently in group Z (29%) as compared to groups B (4%) and G (4%).Conclusions: ILM peeling does not adversely or positively affect the distance and near vision, visual field and MCharts. Therefore ILM removal could be considered in only selected cases of "macula-off" retinal detachment.

“…The vertical and horizontal metamorphopsia score, assessed using M-CHARTS V, was similar across the groups in our study. Matsumoto, on the other hand, reported higher values in patients with advanced (grade 2) ERM [17,20]. The result was dependent on the severity of ERM in the group without ILM peeling.…”

“…Cross-sectional and longitudinal studies of a range of diseases, including macular holes, glaucoma, age-related macular degeneration (AMD), macular edema, and diabetic retinopathy, have been performed. [3][4][5][6][7][8][9][10][11][12][13][14][15][16] The StratusOCT system (Carl Zeiss Meditec, Dublin, CA) is in widespread clinical use and can provide detailed cross-sectional images and quantitative information on retinal pathology. An OCT image with 8-to 10-μm axial resolution and 512 axial scans may be acquired in 1.3 seconds using StratusOCT.…”

Objective-To assess high-speed ultrahigh-resolution optical coherence tomography (OCT) image resolution, acquisition speed, image quality, and retinal coverage for the visualization of macular pathologies. Design-Retrospective cross-sectional study.Participants-Five hundred eighty-eight eyes of 327 patients with various macular pathologies.Methods-High-speed ultrahigh-resolution OCT images were obtained in 588 eyes of 327 patients with selected macular diseases. Ultrahigh-resolution OCT using Fourier/spectral domain detection achieves ~3-μm axial image resolutions, acquisition speeds of ~25 000 axial scans per second, and >3 times finer resolution and >50 times higher speed than standard OCT. Three scan protocols were investigated. The first acquires a small number of high-definition images through the fovea. The second acquires a raster series of high-transverse pixel density images. The third acquires 3-dimensional OCT data using a dense raster pattern. Three-dimensional OCT can generate OCT fundus images that enable precise registration of OCT images with the fundus. Using the OCT fundus images, OCT results were correlated with standard ophthalmoscopic examination techniques. Main Outcome Measures-High-definition macular pathologies.Results-Macular holes, age-related macular degeneration, epiretinal membranes, diabetic retinopathy, retinal dystrophies, central serous chorioretinopathy, and other pathologies were imaged and correlated with ophthalmic examination, standard OCT, fundus photography, and fluorescein angiography, where applicable. High-speed ultrahigh-resolution OCT generates images of retinal pathologies with improved quality, more comprehensive retinal coverage, and more precise registration than standard OCT. The speed preserves retinal topography, thus enabling the visualization of subtle changes associated with disease. High-definition high-transverse pixel density Conclusions-High-definition 3-dimensional imaging using high-speed ultrahigh-resolution OCT improves image quality, retinal coverage, and registration. This new technology has the potential to become a useful tool for elucidating disease pathogenesis and improving disease diagnosis and management.Optical coherence tomography (OCT) is a medical imaging technology that can perform highresolution cross-sectional imaging of tissue morphology in situ and in real time. Optical coherence tomography imaging is analogous to ultrasound, except that it uses light rather than sound and measures the echo time delay and magnitude of reflected or backscattered light using low-coherence interferometry. Cross-sectional images are generated by directing an optical beam onto tissue and scanning it in the transverse direction, thus yielding a data set that can be displayed as false-color or grayscale images. Despite the successful clinical application of OCT technology, there are several limitations. Without using techniques such as eye tracking, the total permissible image acquisition time is limited by subject eye motion, which can cause imag...
