filtration surgery
Học thuậtThân thiện
Definition
Noun: - A surgical procedure for glaucoma: A type of eye surgery that creates a new drainage pathway to allow excess aqueous humor (the fluid inside the eye) to escape, thereby reducing intraocular pressure.
Usage
- This term is used specifically in medical contexts, particularly ophthalmology, to describe a standard surgical treatment for glaucoma.
- It is a formal, technical term.
Examples
- The patient's intraocular pressure was not controlled with medication, so the ophthalmologist recommended filtration surgery.
- Filtration surgery remains a cornerstone in the surgical management of open-angle glaucoma.
- The success of the filtration surgery was evident in the normalized pressure readings during the follow-up visit.
Advanced Usage
- Trabeculectomy: This is the most common type of filtration surgery, where a small flap is created in the sclera (the white of the eye) to allow fluid to drain.
- The surgeon performed a trabeculectomy, a specific form of filtration surgery, to create a new drainage channel.
Variants and Related Words
- Filtering surgery: An alternative term with the same meaning.
- Glaucoma surgery: A broader category that includes filtration surgery and other procedures.
- Drainage implant surgery: A different surgical approach that involves inserting a tube, often used when standard filtration surgery is not suitable.
Synonyms
- Drainage surgery (in the specific context of glaucoma)
- Glaucoma filtering procedure
