Gonioscopy

Gonioscopy is a method of examining the angle between the cornea and the iris of the eye. This angle is called the Goldmann angle and plays an important role in the optical system of the eye.

Gonioscopy allows you to assess the condition of the Goldmann angle, which can be impaired in various eye diseases, such as glaucoma, cataracts or eye trauma. An abnormal Goldmann angle can lead to a variety of vision problems, such as decreased visual acuity, blurred and double vision, and an increased risk of developing glaucoma.

To perform gonioscopy, a special device is used - a gonioscope. It consists of two parts: the eyepiece part and the optical part. The eyepiece includes a lens and an eyepiece that allow the examiner to observe the patient's eye. The optical part consists of a mirror and a prism, which allow you to transform light rays and direct them to the eyeball.

During gonioscopy, the doctor uses a gonioscope to evaluate the Goldmann angle. To do this, he looks at the eye through the eyepiece of the gonioscope and evaluates the angle between the cornea and the iris. If the angle is small, this may indicate the presence of glaucoma or other vision problems.

In general, gonioscopy is an important method for diagnosing and treating eye diseases, which allows you to assess the condition of the eye and identify possible vision problems in the early stages.

Gonioscopy is a study of the conjunctiva of the eye and the angle of the anterior chamber. The inspection is carried out in transmitted light. Properly performed gonioscopy allows you to obtain data on the condition of the precorneal surface of the sclera, iris, ciliary body and cornea. Gonioscopy is classified according to several criteria: objects of study, degree of invasiveness, and organs being examined. In addition, a distinction is made between direct and indirect gonioscopy. In the latter case, the patient's eye is exposed to external influences, and the doctor places the necessary medical instruments under the patient's eyelids. Direct gonioscopy can be performed simply on a chair, although, of course, it is much more comfortable to conduct research on a special pneumoscopy table. If it is necessary to examine both eyes, the patient is asked to look in front of him (or vice versa in the other direction) and look down. Each eye is examined in turn to achieve the greatest accuracy of information and prevent movement of the eyeball, if required by the procedure. Indirect gonioscopy involves deep penetration into the structures of the organ.
