We used spectral-domain optical coherence tomography (SD-OCT) to compare the foveal and parafoveal structures of 19 subjects aged 16-58 years (8 men, 11 women): 6 amblyopic patients with eccentric fixation, 5 amblyopic patients with central fixation, and 8 visually normal controls. We obtained foveal horizontal line scans using SD-OCT on all of the patients and controls. The total and layer thicknesses at foveal areas were analyzed. The mean (SD) ages of individuals in the eccentric fixation, central fixation, and control groups were 43.0 (13.9), 42.2 (16.3), and 38.5 (15.5) years, respectively. We observed no significant differences in the foveal or parafoveal retinal thicknesses at 500 and 1,500 μm from the foveal center among the 3 groups or between the amblyopic and fellow eyes. No significant differences were observed in the thickness of the ganglion cell complex layer or outer retinal layer at 500 and 1,500 μm from the foveal center among the three groups or between the two eyes. Overall, our SD-OCT analyses revealed no characteristic structural change in foveal regions in amblyopic eyes irrespective of the fixation behavior.

Background: To analyse the effect of suprachoroidal injection (SChI) of triamcinolone acetonide (TA) on macular thickness (CRT), ectopic inner foveal layer thickness (EIFL-T) and best corrected visual acuity (BCVA) in pseudophakic patients undergoing vitrectomy for epiretinal membrane (iERM) compared to intravitreal injection of TA (IVTA).
Methods: Prospective matched comparison of patients undergoing vitrectomy for Govetto stage 3 and 4 iERM. 25 eyes receiving IVTA (G-1) were compared to 23 eyes receiving SChI-TA (G-2) during vitrectomy.

Purpose: Utilizing Swept source optical coherence tomography angiography (SS-OCTA) investigates the changes in the vascular characteristics of the choriocapillaris and larger vascular layers, including Sattler's and Haller's layers, in the macular region of young myopia patients, in order to to Enhance our comprehension of the underlying mechanisms of the pathogenesis of myopia.
Methods: A retrospective analysis was performed on 103 young adults (154 eyes) that underwent SS-OCTA. Axial lengths (AL) were measured, 64 eyes with AL < 26.

Purpose: Focusing the premature birth and its potential complications, this study analyzes Foveal Avascular Zone (FAZ) measured by Optical Coherence Tomography Angiography (OCTA) and its correlation with the severity of prematurity and neonatal growth.
Methods: A cross-sectional comparative study was performed, involving 71 children school-age with history of prematurity and a full-term children control group. Several variables from the neonatal period were collected, such as Gestational Age (GA), Birth Weight (BW), initial Weight Gain (WG) and Retinopathy of Prematurity (ROP).

Purpose: We investigated changes in macular topography and their association with visual acuity and metamorphopsia in the idiopathic epiretinal membrane (iERM).
Methods: Twenty-four eyes that underwent vitrectomy and ERM removal with internal limiting membrane peeling were included in this study. Best-corrected visual acuity (BCVA) and horizontal/vertical metamorphopsia scores (h and vM-scores in the M-chart) were assessed.

Purpose: To evaluate changes in the retinal microvasculature using widefield swept-source optical coherence tomography angiography (SS-OCTA) following three anti-vascular endothelial growth factor (anti-VEGF) loading injections for diabetic macular edema (DME).
Methods: Thirty-four treatment-naïve patients with DME received an initial three loading injections, followed by injections on an as-needed basis. Macular ischemia was evaluated based on the foveal avascular zone (FAZ) area, perfusion density, and vessel density on a 3 × 3-mm SS-OCTA image.
