Há 1 dia · Purpose To evaluate the reflectivities of the retinal pigment epithelium (RPE), ellipsoid zone (EZ), and external limiting membrane (ELM) in the central fovea, perifoveal, and parafoveal regions with Optical Coherence Tomography (OCT) and the change in choroid vascular index (CVI) in patients using hydroxychloroquine (HCQ). Methods Sixty-one patients underwent HCQ treatment; age and sex ...
Há 3 dias · Upon qualitative analysis, one-third of ONH eyes lacked signs of an optic cup while two-thirds displayed reduced or no sign of a foveal pit. Interestingly, fellow eyes of those with ONH had shorter disc diameter (1,446µm ±404µm vs. 1,751µm ±221µm) and reduced foveal depth (93µm ±27µm vs. 119µm ±19µm); however, similar GCC thickness ...
Há 2 dias · Superficial capillary plexus vessel density (SCP-VD), deep capillary plexus vessel density (DCP-VD), foveal avascular zone (FAZ), central macular thickness (CMT), foveal diameter and depth were analyzed by OCTA. Results Children with ROP were shown to have significantly higher fovea SCP-VD, fovea DCP-VD, and CMT, and decreased FAZ area.
Há 1 dia · Citation 4 As the distribution of cones changes rapidly moving away from the fovea, retinal morphology affects light scattering patterns significantly. Citation 5 Mitochondria and lysosomes are identified as the organelles that scatter the most light in the cell, and their optical properties, particularly scattering coefficients, are associated with their structural integrity and functional ...
Há 10 horas · The structural and refractive implications of these deposits remain uncertain . Because the deposits primarily exist adjacent to the ring segments channel and do not affect the central area of the cornea, it is believed that they have no impact on vision [ 7 ], but since the deposits might be related to an inflammatory reaction of the corneal stroma, they could be related to anterior stromal ...
Há 3 dias · In that context, we introduce Immunocto, a massive, multi-million automatically generated database of 6,848,454 human cells, including 2,282,818 immune cells distributed across 4 subtypes: CD4 + T cell lymphocytes, CD8 + T cell lymphocytes, B cell lymphocytes, and macrophages. For each cell, we provide a 64 64 64\times 64 64 × 64 pixels 2 H&E ...
Há 5 dias · Dataset use and workflow from algorithm development through validation and deployment. Whole slide images (WSI) from three different cohorts were used for model development: 407 from The Cancer ...
