Sclerotomy is a medical term that refers to a surgical procedure that involves making incisions in the sclera, which is the white, outer layer of the eye. The word is pronounced as "skler-ot-uh-mee" with the phonetic transcription /sklɛrˈɒtəmi/. The spelling of the word reflects its Greek origins, where "sclero" means hard and "tomy" means to cut. This procedure is commonly used in ophthalmology to treat conditions such as glaucoma and intraocular tumors. It is important to spell the word correctly to ensure clear and accurate communication in medical contexts.
Sclerotomy is a noun that refers to a surgical procedure that involves making an incision into the sclera, which is the tough, white outer layer of the eye. The sclera provides structural support and protection to the delicate inner parts of the eye. This procedure is commonly performed to gain access to the inner eye for various surgical interventions.
During a sclerotomy, a surgeon creates a small or large incision in the sclera using a sharp instrument, such as a scalpel or a laser. The size and location of the incision may vary depending on the purpose of the surgery. This technique allows the surgeon to access the vitreous cavity, which is the space filled with a gel-like substance called the vitreous humor that lies between the lens and the retina.
Sclerotomies are most commonly performed during vitrectomy surgeries, which involve removing the vitreous humor and replacing it with a clear solution. They can also be performed to insert or remove intraocular devices, such as implants or drainage tubes, or to repair retinal detachments or tears.
After the surgical procedure is completed, the sclerotomy incisions are often closed using sutures or other techniques to allow for proper healing. Depending on the exact procedure, the patient may need to wear an eye patch or follow specific post-operative care instructions to promote recovery.

The word "sclerotomy" is derived from the Greek roots "sclero-" meaning "hard" or "sclera" (the tough, white outer layer of the eyeball) and "-tomy" which means "cutting" or "incision". Therefore, "sclerotomy" literally means "incision of the sclera". In medical terminology, it refers to a surgical procedure that involves making an incision in the sclera for various purposes, such as accessing the interior of the eye during certain eye surgeries.
