It’s called macular ERM when the fibrous proliferation...

... analyzed by optical coherence tomography (OCT). The choroidal vessels in some cases were evaluated with OCT angiography. M-charts were used to determine the metamorphopsia. Results: MSFBs occurred in 17 (29.3%) and 8 (5.4%) eyes given SB and PPV, respectively. MSFBs appeared 5.6 ± 5.5 weeks after surgery...

.... Glaucoma Tomography Optical coherence tomography Optic nerve diseases Glaucoma is a multivariable optic neuropathy, characterized by distinctive findings of the optic nerve head (ONH), retinal nerve fiber layer (RNFL) thinning, and visual field (VF) defects, which can ultimately lead...

... with and without diabetic retinopathy (DR). Methods: This cross-sectional study included patients with and without diabetes. Patients underwent comprehensive ocular examination. CT was obtained using spectral-domain optical coherence tomography (SD-OCT) with enhanced depth imaging (EDI) mode. Clinical parameters...

... Optical coherence tomography Glaucoma is a specific form of optic neuropathy associated with increased intraocular pressure (IOP) and non-IOP factors, such as ischemic and cellular pathophysiologic mechanisms [ 1-3 ]. Though considerable research has been invested in identifying morphological...

Results: A total of 142 eyes from 142 patients (28...

...: To evaluate the diagnostic accuracy of digital retinal fundus image (DRFI) analysis in detecting DME using three manual grading systems (MGS) and comparing it with optical coherence tomography (OCT) findings. Method: A total of 287 DRFI of 287 eyes were analysed. Non-stereoscopic 45° images were acquired...

... defects measured with optical coherence tomography (OCT). Methods: 5 young (aged 3-6 years) and 5 adult patients with hemianopia, 10 healthy preschoolers (mean age 4.4 years), and 10 healthy adults (mean age 25.3 years) were tested with SVOP and OCT (focusing on the ganglion cell layer, GCL+). In adults...
