sclerotomy
Pronunciation: skler-AH-toh-mee
Surgical incision through the sclera to access intraocular structures or relieve pressure.
Full Definition
A sclerotomy is a carefully placed full-thickness incision through the sclera, the white fibrous outer layer of the eye. This fundamental technique is used in various ophthalmic procedures including vitreoretinal surgery, where multiple sclerotomies create ports for instruments. The size and location of sclerotomies are critical factors affecting wound healing and post-operative complications. Modern techniques often employ self-sealing sutureless sclerotomies, typically 23-gauge, 25-gauge, or 27-gauge, which reduce surgical time and improve patient comfort.
Usage
Usage note: Not to be confused with sclerostomy, which creates a permanent opening for drainage.
