These estimates were summarized as retinal arteriolar branching angle and retinal venular branching angle, representing the average branching angle of arterioles and venules, respectively.
Retinal vascular branching angle was defined as the first angle subtended between two daughter vessels at each vascular bifurcation [26].
The disparity signals (in pixels) which are extracted by stereo matching algorithms can be converted to retinal disparities (in angles) given the viewing parameters and the size of the display [24].
The left eye of each animal was treated with intravitreal 0.40 nmol MK801 at the same time as A β. Wide-angle retinal images were recorded 2 h after intravitreal annexin (green) and PI (red) staining, as previously described.
Camera settings, including angle of retinal photography, remained unchanged.
Emphasis is laid on age-related macular degeneration, open angle glaucoma, retinal vessel diameters and, recently, myopia and other refractive abnormalities.
These measurements were used to make accurate conversions from visual angle to retinal distance [ 20, 39], which were the units used in the spatiotemporal plot analysis.
We investigated whether the angle of specific retinal blood vessels the most temporal major retinal blood vessels superiorly and inferiorly diverging from the optic nerve head has an impact on the RNFL thickness around the TSNIT graph.
To evaluate the accuracy of detecting clinically significant retinopathy of prematurity (ROP) using wide-angle digital retinal photography.
One essential feature of the resulting network is that it must be selective but simultaneously invariant: the same feature can appear under changing retinal positions, sizes, rotational angles or partial occlusion.
Infants underwent ocular examination within 42 days after birth using a flashlight, retinoscope, hand-held slit lamp microscope and wide-angle digital retinal image acquisition system.
