The Alpide belt is a system of sutures stretching across Eurasia within which the Cimmerian blocks are now located. In the 1980s Turkish geologist Celâl Şengör finally extended Stöcklin's Iranian microcontinent further west to Turkey and further east to Tibet and the Far East. [16]
Cataract surgery has a long history in Europe, Asia, and Africa, with Chrysippus of Soli, a stoic Greek philosopher providing the earliest account. [106] Couching was the original form of cataract surgery, and was used from antiquity. It is still occasionally found in traditional medicine in parts of Africa and Asia.
MSICS is a procedure that was developed to reduce costs in comparison with phacoemulsification, which requires expensive high-tech equipment that needs skilled maintenance, and is relatively unsuited to less developed regions, and to eliminate the need for suturing the incision, by using a self-sealing incision.
Ocular sutures – are sutures surrounding the edges of the compound eye. Trilobites with these sutures lose the entire surface of the eyes when molting. It is common among Cambrian trilobites. Palpebral sutures – are sutures which form part of the dorsal facial suture running along the top edges of the compound eye.
•Guarded eye speculum (left and right)-do-; heavy instrument but can keep eyelashes out of the operating field with its "guard" and hence left or right ones are required •Wire Speculum: to keep the eyes open during any operation; light wire instrument Needle holders: holding the needle in position while applying sutures •Silcock's needle ...
Couching is still occasionally found in traditional medicine in parts of Africa and Asia. In 1753, Samuel Sharp performed the first-recorded surgical removal of the entire lens and lens capsule, equivalent to what became known as intracapsular cataract extraction. The lens was removed from the eye through a limbal incision. [1]
The first trial to do so is the TAGS randomised controlled trial which investigated if eye drops or trabeculectomy is more effective in treating advanced primary open-angle glaucoma. After two years researchers found that vision and quality of life are similar in both treatments.
Tenon's capsule (/ t ə ˈ n oʊ n /), also known as the Tenon capsule, fascial sheath of the eyeball (Latin: vagina bulbi) or the fascia bulbi, is a thin membrane which envelops the eyeball from the optic nerve to the corneal limbus, separating it from the orbital fat and forming a socket in which it moves.
