gonioscopy
Pronunciation: goh-nee-AH-skoh-pee
Diagnostic examination technique using a specialized lens to visualize the drainage angle of the eye.
Full Definition
Gonioscopy is an essential diagnostic procedure in ophthalmology that enables direct visualization of the iridocorneal angle (drainage angle) using a goniolens or gonioscopy lens placed on the eye. This examination is crucial for evaluating patients with glaucoma or suspected glaucoma, as it allows assessment of angle anatomy, identification of peripheral anterior synechiae, detection of angle closure, and evaluation of surgical outcomes such as trabeculectomy blebs. The procedure requires topical anesthesia and a coupling agent, and findings are typically documented using standardized grading systems such as the Shaffer or Spaeth classification.
Usage
Usage note: Always document specific angle findings using standardized grading systems for consistency.
