gonioscopy

In many cases it can be seen via gonioscopy.

Using a special lens to look at the eye (gonioscopy)

The angle is seen using a technique called gonioscopy.

Gonioscopy: An examination of the front part of the eye between the cornea and iris.

Although the details vary based on the type of goniolens used, in general the gonioscopy process involves:

If you have glaucoma, gonioscopy can help your doctor see which type of glaucoma you have.

See tonometry and gonioscopy in the Exams and Tests section of the topic Glaucoma.

Tonometry and gonioscopy can be done using a slit lamp and may be part of a slit lamp exam.

"Slit-Lamp Gonioscopy."

Routine evaluation of iris melanomas includes gonioscopy, transillumination of the globe, and indirect ophthalmoscopy with 360 of scleral depression.

In order to combat glaucoma in the breed, the breed clubs recommend that Dandies should have a procedure called a gonioscopy conducted on them at regular intervals throughout their lives.

In the absence of synechiae, indentation gonioscopy may reveal the area where the cornea and iris are truly anatomically attached, as compared to where they are simply apposed against each other.

Proxymetacaine hydrochloride ophthalmic solution (eye drops) is indicated for procedures such as tonometry, gonioscopy, removal of foreign bodies, or other similar procedures requiring topical anesthesia of the cornea and conjunctiva.

Most importantly, the size and shape of the instrument - a smaller front surface that rests on the cornea without requiring lubricating fluid, only the patient's tear film - allows for indentation gonioscopy, which can be used for further diagnosis.

These lenses include the Goldmann 3-mirror lens, gonioscopy single-mirror/ Zeiss 4-mirror lens for (ocular) anterior chamber angle structures and +90D lens, +78D lens, +66D lens & Hruby (-56D) lens, the examination of retinal structures is accomplished.

Indentation gonioscopy: An extension of the above two concepts, indentation gonioscopy involves the applied pressure of the goniolens against the eye, acutely raising the intraocular pressure in the anterior chamber and subsequently opening up the iridocorneal angle mechanically, allowing a greater understanding of the nature of the anterior synechiae.
