====== Central quadrantotomy ======

Central [[quadrantotomy]] is a surgical [[procedure]] used to treat a condition called [[homonymous hemianopia]], which is a [[visual field defect]] that occurs as a result of damage to the [[optic pathway]] in the brain. In this procedure, a portion of the [[optic nerve]] [[fiber]]s that are responsible for transmitting visual information from the central part of the visual field to the brain is cut. This results in a smaller [[visual field]], but it can help patients with homonymous hemianopia to better navigate and function in their daily lives.

Central quadrantotomy is typically performed under [[general anesthesia]], and the procedure involves making a small incision in the scalp to access the skull. The surgeon then creates a small hole in the skull to gain access to the brain and uses a surgical instrument to carefully cut the targeted optic nerve fibers. After the procedure, patients may experience some temporary visual disturbances or headaches, but these usually resolve within a few days. Rehabilitation and therapy may be necessary to help patients adjust to their new visual field and improve their functional abilities.
