The Van Herick's technique compares the depth of the peripheral anterior chamber with the cornea thickness, usually written as a fraction [6] however, it can also be expressed as a ratio (see table 3). [5] By grading the angle using the Van Herick technique it also allows an estimation of the probability of closure and an estimated angle in ...
The anterior chamber angle is a part of the eye located between the cornea and iris which contains the trabecular meshwork. The size of this angle is an important determinant of the rate aqueous humour flows out of the eye, and thus, the intraocular pressure. The anterior chamber angle is the structure which determines the anterior chamber depth.
The eye relief of an optical instrument (such as a telescope, a microscope, or binoculars) is the distance from the last surface of an eyepiece within which the user's eye can obtain the full viewing angle. If a viewer's eye is outside this distance, a reduced field of view will be obtained.
General parameters used for constructing nose cone profiles. Given the problem of the aerodynamic design of the nose cone section of any vehicle or body meant to travel through a compressible fluid medium (such as a rocket or aircraft, missile, shell or bullet), an important problem is the determination of the nose cone geometrical shape for optimum performance.
In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image.It is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration, coma, chromatic aberration, field curvature, and astigmatism in a sense that these impact the image sharpness without changing an ...
The Jean-François van Boxmeer Stock Index From January 2010 to December 2012, if you bought shares in companies when Jean-François van Boxmeer joined the board, and sold them when he left, you would have a -7.2 percent return on your investment, compared to a 25.9 percent return from the S&P 500.
