“…METHODS: In this cross-sectional study, 93 participants (i.e., 93 eyes) with emmetropia and myopia underwent ocular imaging via anterior segment optical coherence tomography. We acquired raw B-scan OCT images along each of the four meridians (superior, inferior, nasal, and temporal), The AST was estimated from the limbus to a distance of 6 mm. …”

“…METHODS: Based on 4574 UWFIs, a deep learning model was trained and validated that can identify normal fundus and eight common fundus diseases, namely referable diabetic retinopathy, retinal vein occlusion, pathologic myopia, retinal detachment, retinitis pigmentosa, age-related macular degeneration, vitreous opacity, and optic neuropathy. The model was tested on three test sets with data volumes of 465, 979, and 525. …”

“…Macular thickness, peripapillary retinal nerve fiber layer (pRNFL) thickness, and macular ganglion cell complex (GCC) thickness were measured by optical coherence tomography. Eyes were classified into three groups: Group 1, no GCC defect; Group 2, GCC defect confined to parafoveal area; and Group 3, GCC defects extending beyond the parafoveal area. …”

“…AIM: To evaluate and compare the shear bond strength (SBS) of Embrace WetBond(TM) (EWS) Pit and Fissure Sealant (PF sealants) with or without the use of a universal dental adhesive system Scotchbond(TM) Universal Adhesive (SBU) using different bonding and curing protocols and to assess and compare the mode of failure as determined by visualization of the fractured surfaces of the test specimens after shear testing under an optical microscope at a magnification of 20×. MATERIALS AND METHODS: A total of 85 samples were prepared for testing SBS on enamel on caries-free, extracted permanent human molars. …”

“…PATIENTS AND METHODS: We evaluated best-corrected visual acuity (BCVA), treatment interval, central subfield retinal thickness (CST) and the presence of intra-retinal (IRF), subretinal (SRF) and/or sub-retinal pigment epithelium (sub-RPE) fluid on optical coherence tomography (OCT). Concurrently, patients were carefully examined for signs of intra-ocular inflammation (IOI) and other adverse events. …”
