Sclerotomy is a medical intervention that involves surgical cutting in the white area of the eye, known as the sclera. [1] The goal of this intervention is usually done to correct defects in sclera that resulted as a complication of glaucoma of other ocular diseases. [2] Sclerotomy can be divided into anterior sclerotomy and posterior ...
Laser eye surgery or laser corneal surgery is a medical procedure that uses a laser to reshape the surface of the eye to correct myopia (short-sightedness), hypermetropia (long-sightedness), and astigmatism (uneven curvature of the eye's surface). Importantly, refractive surgery is not compatible with everyone, and people may find on occasion ...
take (often effectively a noun meaning "prescription"—medical prescription or prescription drug) rep. repetatur: let it be repeated s. signa: write (write on the label) s.a. secundum artem: according to the art (accepted practice or best practice) SC subcutaneous "SC" can be mistaken for "SL," meaning sublingual.

The technique he used during the procedure, injecting the sclera with blue dye, is similar to an established method practiced by surgeons who install eye implants. [11] Larratt's wife Rachel underwent a procedure where the surgeon injected small drops of saline to create a fluid-filled pocket between the conjunctiva and the sclera, where he ...
Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized by raised intraocular pressure (IOP). There are many glaucoma surgeries, and variations or combinations of those surgeries, that facilitate the escape of excess aqueous humor from the eye to lower intraocular pressure, and a few that lower IOP by decreasing the production of ...
[9] [14] [15] Human sclera is thought to offer the best support, as well as Lyodura, which is biologically compatible with the eyeball and has sufficient tensile strength. Artificial materials, such as nylon or silicone, are not suggested. [10] [clarification needed] Sclera from cadaver’s or animal tendons run the risk of being rejected.
Intraocular pressure may be lowered by allowing drainage of aqueous humor from within the eye to the following routes: (1) filtration through the sclerotomy around the margins of the scleral flap into the filtering bleb that forms underneath the conjunctiva, (2) filtration through outlet channels in the scleral flap to underneath the conjunctiva,(3) Filtration through the connective tissue of ...
Pronunciation follows convention outside the medical field, in which acronyms are generally pronounced as if they were a word (JAMA, SIDS), initialisms are generally pronounced as individual letters (DNA, SSRI), and abbreviations generally use the expansion (soln. = "solution", sup. = "superior").
