The direction of the microfibrils is called microfibril angle (MFA). In the secondary cell wall of fibres of trees a low microfibril angle is found in the S2-layer, while S1 and S3-layers show a higher MFA . However, the MFA can also change depending on the loads on the tissue. It has been shown that in reaction wood the MFA in S2-layer can ...
Monofixation syndrome (MFS) (also: microtropia or microstrabismus) is an eye condition defined by less-than-perfect binocular vision. [1] It is defined by a small angle deviation with suppression of the deviated eye and the presence of binocular peripheral fusion. [2] That is, MFS implies peripheral fusion without central fusion.
This is a red pigment seen at the back of the eye in animals that have a white background to their eye called Tapetum lucidum. The pigment is not noticeable under photopic and mesopic conditions. The principle that the wavelength sensitivity does not change during scotopic vision led to the ability to detect two functional cone classes in ...
A microfibril is a very fine fibril, or fiber-like strand, consisting of glycoproteins and cellulose. It is usually, but not always, used as a general term in describing the structure of protein fiber, e.g. hair and sperm tail.
Based on Wavefront map of the eye and with the use of laser a lens is shaped to compensate for the aberrations of the eye and then put in the eyeglasses. Ultraviolet Laser can alter the refractive index of curtain lens materials such as epoxy polymer on a point by point basis in order to generate the desired refractive profile.
A couple has been arrested after authorities say they performed a botched circumcision on their son at their central Missouri home last week.. Prosecutors charged Tyler Wade Gibson, 35, with one ...
Those with small iridodialyses may be asymptomatic and require no treatment, but those with larger dialyses may have corectopia or polycoria and experience monocular diplopia, glare, or photophobia. [3] [4] [5] Iridodialyses often accompany angle recession [6] and may cause glaucoma [7] or hyphema. [8] Hypotony may also occur. [9]
