OPT 210 GONIOSCOPY EXAM QUESTIONS AND CORRECT
ANSWERS 100% CORRECT!!
What is gonio used for?
visual inspection of the anterior chamber angle through a gonio prism
What are indications for gonio?
-determining dilation safety for van herick grade 2 or less
-high or asymmetric IOP (>24 or asymmetry ≥3)
-diagnosis and differentiation of glaucoma
-treatment of acute angle closure
-evaluating anterior synechiae in uveitis or trauma or angle closure
-concern for neovascularization
-evaluating in tumor, foreign body, congenital anomaly, surgical procedure or implant
-procedures
, What procedures can gonio be used in?
-laser trabeculoplasty
-iridoplasty
-peripheral iridotomy
-MIGS (micro-invasive glaucoma surgery)
When is gonio contraindicated?
