What is the use of gonioscopy?

Gonioscopy is an eye test that checks for signs of glaucoma. It uses a special lens and slit lamp to evaluate your eye’s drainage angle (anterior chamber angle). If the drainage angle is blocked or closed, you may have glaucoma. Gonioscopy is one of many tests you may need if you are at risk for glaucoma.

What is meant by gonioscopy?

Listen to pronunciation. (GOH-nee-OS-koh-pee) A procedure in which a gonioscope (special lens) is used to look at the front part of the eye between the cornea (the clear layer) and the iris (the colored part of the eye). Gonioscopy checks for blockages in the area where fluid drains out of the eye.

Who invented gonioscopy?

In 1899, the Greek ophthalmologist Alexios Trantas was the first to visualise the angle in vivo and coined the term ‘gonioscopy’. He made a number of other important contributions to ophthalmology.

Can I take gabapentin with glaucoma?

Patients who took gabapentin the year prior to diagnosis were at higher risk than current users. If your patients have taken gabapentin to manage chronic pain or other conditions, they may have a higher chance of developing acute angle-closure glaucoma, Canadian researchers report.

What is YAG laser iridotomy?

A YAG laser iridotomy is a treatment for anatomically narrow angles, a condition that affects your eye’s ability to drain fluid. Similar to inflating a basketball with too much air, lack of drainage can result in increased eye pressure. Having anatomically narrow angles puts you at risk for acute closed-angle glaucoma.

How do I bill a CPT 92020?

To report this test, use CPT 92020, Gonioscopy (separate procedure). CMS defines 92020 as bilateral, so reimbursement is for both eyes.

Why is tonometry done before gonioscopy?

Extra pressure applied to the eye when performing gonioscopy can lead to a temporary IOP reduction. So, always perform tonometry before gonioscopy.

Can I drive after a gonioscopy?

If you wear contact lenses, remove them before this test and do not put them back in for 1 hour after the test or until the medicine used to numb your eye wears off. If your eyes might be dilated during your examination, your doctor may suggest that you arrange for someone to drive you home after the test.

Which instrument is required while performing gonioscopy?

Direct Gonioscopy It can be performed using a direct goniolens and either a binocular microscope or a slit-pen light.
