Then, mechanical properties and progressive failure processes for rock masses with different dip angle structure
planes are studied, and the macroscopic fracture, mechanical responses, and AE responses of rock masses are analyzed.
Under the ophthalmic endoscopic system, the surgeon can directly observe the angle structure
and relative anatomical positions.
The possible etiology mentioned above does not directly relate to angle structure
. Therefore, we hypothesized that PSS may occur in patients with a narrow or closed angle.
[1, 2] The placement of IOL in the posterior chamber rather than Anterior or Iris fixated lenses reduces the risk of various complications like Corneal endothelial damage, damage to anterior chamber angle structure
, pupillary block glaucoma, hyphema, uveitis, iris chafing, dislocation and pseudo phakodonesis.
iOCT then was performed to assess the gonio structures using spectral-domain iOCT (RESCAN 700, Carl Zeiss Meditec Japan, Tokyo, Japan); however, the angle structure
was not visualized through the limbal tissue because of poor penetration of the light source.
Which angle structure
is the MOST anterior in the eye?
The angle structure
configuration is quantified by the following six features: (1) mean of the continuous measurement of the angle opening distance; (2) area of the trapezoidal profile of the iridocorneal angle centered at Schwalbe's line; (3) mean of the iris curvature from the extracted iris image; (4) complex shape descriptor, fractal dimension, to quantify the complexity, or changes of iridocorneal angle; (5) ellipticity moment shape descriptor; and (6) triangularity moment shape descriptor.
