Exotropia is a form of strabismus where the eyes are deviated outward. It is the opposite of esotropia and usually involves more severe axis deviation than exophoria. People with exotropia often experience crossed diplopia. Intermittent exotropia is a fairly common condition. "Sensory exotropia" occurs in the presence of poor vision in one eye.
A prism of power 1 Δ would produce 1 unit of displacement for an object held 100 units from the prism. [2] Thus a prism of 1 Δ would produce 1 cm visible displacement at 100 cm, or 1 metre. This can be represented mathematically as: = where is the amount of prism correction in prism dioptres, and is the angle of deviation of the light.
Egyptian geometry. Egyptian geometry refers to geometry as it was developed and used in Ancient Egypt. Their geometry was a necessary outgrowth of surveying to preserve the layout and ownership of farmland, which was flooded annually by the Nile river.
A 36 square cubit area was known as a kalamos and a 144 square cubit area as a hamma. [17] The uncommon bikos may have been 1 + 1 ⁄ 2 hammata or another name for the cubit strip. [17] The Coptic shipa (ϣⲓⲡⲁ) was a land unit of uncertain value, possibly derived from Nubia. [43]
Siamese crocodiles are a freshwater species that can grow up to 4 meters (13.1 feet) in length. They have a prominent bony crest at the back of the head, and were once present in much of mainland ...
Heterophoria is an eye condition in which the directions that the eyes are pointing at rest position, when not performing binocular fusion, are not the same as each other, or, "not straight". This condition can be esophoria, where the eyes tend to cross inward in the absence of fusion; exophoria, in which they diverge; or hyperphoria, in which ...
22.1 million (2015) [ 5] Deaths. 16,100 (2015) [ 6] Kidney stone disease, also known as renal calculus disease, nephrolithiasis or urolithiasis, is a crystallopathy where a solid piece of material ( renal calculus) develops in the urinary tract. [ 2] Renal calculi typically form in the kidney and leave the body in the urine stream. [ 2]
