In ophthalmology, gonioscopy is a routine procedure that measures the angle between the iris and the cornea (the iridocorneal angle), using a goniolens (also known as a gonioscope) together with a slit lamp or operating microscope. [1] [2] Its use is important in diagnosing and monitoring various eye conditions associated with glaucoma.
It should not however, be used as a replacement for the gonioscopy examination but rather be used as a means of refuting or confirming the results of a gonioscopy examination. [ 3 ] The Van Herick's technique has become the most commonly used qualitative method of assessing the size of the anterior chamber angle (ACA).
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.
Correct angles of major bones, clean, well-developed joints and tendons, and well-shaped, properly-proportioned hooves are also necessary for ideal conformation. [25] "No legs, no horse" [20] and "no hoof, no horse" [26] are common sayings in the equine world. Individual horses may have structural defects, some of which lead to poor movement or ...
The horse has an oblique angle of shoulder (measured from the top of the withers to the point of shoulder) with the withers set well behind the elbow. Often accompanies a deep chest and high withers. A sloping shoulder is common. It mostly affects jumping, racing, cutting, reining, polo, eventing, and dressage.
In surface science, an instrument called a contact angle goniometer or tensiometer measures the static contact angle, advancing and receding contact angles, and sometimes surface tension. The first contact angle goniometer was designed by William Zisman of the United States Naval Research Laboratory in Washington, D.C. and manufactured by ramé ...
Thomas Detry nearly aced the rowdy par-3 16th hole in a stretch of four closing birdies, shooting a 6-under 65 on Sunday to win the Phoenix Open by seven shots for his first PGA Tour victory. The ...
The forensic term for the midpoint of the mandibular angle is the gonion. The gonion is a cephalometric landmark located at the lowest, posterior, and lateral point on the angle. [ 1 ] This site is at the apex of the maximum curvature of the mandible, where the ascending ramus becomes the body of the mandible.
