Osteo-odonto-keratoprosthesis (OOKP), also known as "tooth in eye" surgery, [1] is a medical procedure to restore vision in the most severe cases of corneal and ocular surface patients. It includes removal of a tooth from the patient or a donor.
The BETT schema classifies open globe injuries as a laceration or a rupture. A ruptured globe occurs when rapid intraocular pressure elevation secondary to blunt trauma results in eyewall failure. [3] The rupture site may be at the point of impact but more commonly occurs at the weakest and thinnest areas of the sclera. [4]
Observations show that an eyewall replacement cycle can lead to the development of an annular hurricane. While some hurricanes develop into annular hurricanes without an eyewall replacement, it has been hypothesized that the dynamics leading to the formation of a secondary eyewall may be similar to those needed for development of an annular eye ...
The common tendinous ring, also known as the annulus of Zinn or annular tendon, is a ring of fibrous tissue surrounding the optic nerve at its entrance at the apex of the orbit. It is the common origin of the four recti muscles of the group of extraocular muscles. It can be used to divide the regions of the superior orbital fissure. [1]
Hurricane Ian was a prolific lightning producer as it strengthened into a Category 5 hurricane on its approach to Florida. Storm chasers along the coast of Florida even witnessed cloud-to-ground ...
The most widely used simulator for laparoscopic surgery today is the da Vinci Surgery Simulator. It is the newest way to practice these procedures that involves the surgeon in the surgery and control of the device. The simulator is a tutorial that prepares a surgeon for the real surgery at the da Vinci Surgical System. It contains real time ...
A novelty eye can cost anywhere from $2,500 to $5,500 -- about the same range as a regular prosthetic -- but they aren't covered by insurance. Andy recalls one patient who was determined to make a return on his investment: He asked . for an eye that featured the Nike swoosh.
Annular dark-field imaging requires one to form images with electrons diffracted into an annular aperture centered on, but not including, the unscattered beam. For large scattering angles in a scanning transmission electron microscope , this is sometimes called Z -contrast imaging because of the enhanced scattering from high-atomic-number atoms.
