Cylindroscopy

Cylindroscopy (cylindroskiascopy) is a diagnostic method that is used to determine the shape and size of the pupil of the eye. This method is based on the use of a special device - a cylinderscope, which allows you to measure the diameter of the pupil and its shape.

A cylinderscope is an optical instrument that consists of two lenses and a cylindrical lens. It allows you to get a clear image of the pupil on the screen. A cylindrical lens allows you to change the shape of the pupil, which allows you to determine its shape and size.

To perform a cylindroscopy, the following steps must be taken:

1. The patient should sit in front of the cylinderscope, which is located at a distance of 50-70 cm from his eyes.
2. The doctor adjusts the cylindrical lens so that the pupil is clearly visible on the cylinderscope screen.
3. The doctor measures the pupil diameter in three directions - vertical, horizontal and diagonal.
4. The doctor may also measure the shape of the pupil. To do this, he uses special templates that allow you to determine the shape of the pupil.
5. The results of cylindroscopy are recorded in a protocol, which is then transmitted to the ophthalmologist.

Cylindroscopy is an important method for diagnosing eye diseases such as glaucoma, retinal dystrophy and others. It allows you to determine the shape and size of the pupil, as well as identify possible changes in its functioning.
