Stereo-ophthalmoscopy

What is stereo ophthalmoscopy?

**Stereo-ophthalmoscopy** is a diagnostic method in ophthalmology, in which the fundus of the eye is examined using a special device. And the name “stereoscopy” comes from the Greek stereos - spatial and skopeo - look. The method can be performed before or after surgery to avoid complications, as well as for accurate selection of glasses or contact lenses. The word “stereo image” itself implies a three-dimensional, three-dimensional image (in English - a three-dimensional stereoscopic object). And ophthalmoscopy is the use of a magnifying device to study the fundus of the eye. How does the device work? The performance of the optical system is determined by the light that is focused at the front of the device. Thanks to the mirrors, it is reflected from the eyeball, after which it enters the doctor’s visual apparatus, where the light rays are combined with the image of the patient’s eye. The doctor compares the resulting images with images of other eyes. If necessary, a new diopter prescription is created that matches the optical properties of the eye and corrects the person’s capabilities. Who is this procedure contraindicated for? Sometimes such examinations may be contraindicated for the following reasons:

1. The patient has farsightedness or high myopia; 2. Inflammatory diseases of the cornea or lens (keratitis, conjunctivitis); 3. Damage to the membrane of the eye due to injury. 4. Mental disorders. 5. Poor tolerance of the procedure. 6. The patient had epileptic seizures. For the first attempt, the device may not be very convenient and is intended for reusable use. This stereofocal lens is used to obtain images of the fundus with slight magnification, in addition, it can cause discomfort for the patient, but its retraction and weaning can be carried out thanks to synchronization, using pedals and buttons. All this leads to a reduction in examination time and an increase in its quality.
