Gonioscope

A gonioscope is a special lens used to view structures located near the edge of the anterior chamber of the eye (between the cornea and iris). These structures are located behind the sclera at the periphery of the cornea and are inaccessible to direct observation.

The gonioscope allows the ophthalmologist to examine the angle of the anterior chamber of the eye and assess the condition of the trabecular meshwork, the area responsible for the outflow of intraocular fluid. This is important for diagnosing and monitoring diseases such as glaucoma.

There are different models of gonioscopes. They can be contact or non-contact. Contact gonioscopes must be pressed directly onto the cornea. They provide a clearer image, but their use requires skill. Non-contact models are easier to use, but do not produce as high quality images.

Thus, a gonioscope is an important diagnostic tool for an ophthalmologist, allowing one to assess the condition of the drainage system of the eye. Its use is critical for early detection and monitoring of glaucoma.

Gonioscopy is a method of examining structures of the eye that are located outside the anterior chamber, but are not directly visible. For this purpose, special lenses are used - gonioscopes.

A gonioscope is an optical device that allows you to see the structures of the eye located behind the edge of the anterior chamber. It consists of a lens and a holder that is attached to the patient's head. The gonioscope lens is shaped like a ring with two holes through which light passes. One hole is located in the center of the lens, and the other is located at the edge of the ring.

When the gonioscope is placed on the patient's head, light passes through a hole in the center of the lens and hits the structures of the eye behind the anterior chamber. This allows you to see structures such as the pupil, iris, lens and others.

Gonioscopy is used in ophthalmology to diagnose various eye diseases, such as glaucoma, cataracts, retinal detachment, etc. It can also be useful during eye surgeries.

Overall, gonioscopy is an important tool in the diagnosis and treatment of eye diseases. Thanks to this method, you can get a more complete picture of the condition of the eye and make the right decision about treatment.

Gonioscopy is a technique for examining structures of the eyeball that lie outside the range of vision of the healthy eye.

In other words, this is a sight located in front of a person’s eyes. Its angle captures the area of ​​the retina untouched by the disease, preserving its entire functionality. It is much more accurate than those such as perimetry, which means it is more suitable for assessing the dynamics of the disease. The eye passes in front of the lens, clearly fixing it in the field of view.

The doctor slowly moves the device over the area of ​​the retina not covered with lesions or cysts. The patient is marked with numbers and letters. At the end of the results the word “norm” is written. If there are deviations, any sign will be assigned to the corresponding site. For example, 1 – visual acuity is preserved, 2 – slight drop, 3 – significant decrease, 4 – no vision.

To carry out the examination itself, the doctor circulates a structure around the patient and places it on the monitor screen. The viewfinder is a device for a gonioscope. There are slits on its glass through which rays of light coming from the device are passed. The distances to individual areas of the retina are fixed between control marks applied to the glass. The stereo lens helps eliminate false data. All zones whose values ​​are similar to each other are included in a common group with the corresponding symbol. The second one comes from the side. It should mark the light rays. If both are projected onto symmetrical areas, the doctor immediately sees the effectiveness of the preventive course. After its completion, you can reuse both devices in order to record the recovery. This guarantees one hundred percent accuracy of the research. This equipment is necessary for retinal microsurgery. It allows you to identify areas as clearly and compactly as possible and carry out differential diagnostics.
