Ophthalmograph Ultrasound

Ultrasound ophthalmograph: How does it work and why is it needed?

An ultrasound ophthalmograph is a medical instrument that is used to diagnose eye diseases. It works by using ultrasonic waves that bounce off the structures of the eye and create an image.

The ultrasound ophthalmography procedure can be performed to diagnose various diseases, including cataracts, glaucoma, diabetic retinopathy, eye tumors and other pathologies. In addition, it can be used to assess the size and shape of the eyeball, the location of the optic nerve, and other structures of the eye.

The procedure is carried out using a special sensor, which is applied to the cornea of ​​the eye using a gel. The transducer generates ultrasonic waves that travel through the structures of the eye and are reflected back to the transducer. This data is then processed by a computer, which creates an image of the eye.

Ultrasound ophthalmography can be especially useful for diagnosing eye diseases in patients in whom conventional ophthalmoscopy is difficult, for example, because of the presence of cataracts or other vision hazards. In addition, this tool may be useful for assessing the effectiveness of treatments for eye diseases such as glaucoma.

In conclusion, an ultrasound ophthalmograph is an important tool for diagnosing eye diseases. It provides additional information about the structure of the eye and can be especially useful for patients in whom conventional ophthalmoscopy is difficult. If you have vision problems or are at risk for developing eye disease, be sure to discuss the possibility of an ophthalmography ultrasound with your doctor.

An ultrasound ophthalmograph is a medical device that is used to measure the eye pressure of patients with glaucoma. This medical device provides painless and rapid measurement of intraocular pressure, which makes it an indispensable tool in diagnosing and monitoring the effectiveness of treatment of the disease.

The operating principle of an ultrasound ophthalmograph is based on measuring the speed of propagation of ultrasonic waves in the tissues of the patient's eye. During operation, the ultrasound ophthalmograph detects the initial movement of fluid particles in the affected eyes and converts them into an acoustic signal. Based on the information received, the devices evaluate blood pressure levels and optic nerve function. Ultrasound ophthalmographs have high measurement accuracy and eliminate subjectivity in the diagnosis and monitoring of glaucoma.

It is important to note that the ophthalmography ultrasound scanner is recommended to be used only once a day for each patient in order to obtain more accurate results in the diagnostic process and treatment monitoring. If necessary, the patient can consult his doctor or a specialized ophthalmologist.

*Ultrasound ophthalmograph - ophthalmological devices working according to the ophthalmography method and using ultrasound. In ophthalmography, ultrashort ultrasound pulses are used to study the anterior part of the eye; their reflection from various layers is recorded, the interface boundaries of which can change both vertically and horizontally, and relative to their normal position. These transformations include, first of all, changes in the refractive index of the eyeball, the presence of eye tumors, changes in the shape of the anterior chamber, lens, cornea and iris, and the thickness of the dense structures of the eye.*

Ultrasound echography is one of the methods for visualizing the structures of the orbit. With regard to the examination of the cornea, the method is in many ways analogous to a traditional examination using a slit lamp, but is distinguished by increased contrast ability (due to the ultrasonic homogeneity of the ultrasonic probe mode), and easily makes it possible to identify various types of neoplasms, as well as assess the thickness of the cornea. Thus, the study may be useful for the diagnosis of keratitis, uveitis, scleritis, tumors of the corneal stroma, and its changes of congenital origin. It should be noted that ultrasound penetrates poorly through the sclera, and it is difficult to detect any changes when examining with an ocular probe, therefore, if there is only a suspicion of any pathology of the anterior chamber, in order to exclude diseases of the sclera, it is necessary to conduct an examination with an IOL probe. Ultrasound examination can also be useful in diagnosing cataracts, especially if diffuse bilateral lesions are detected. Diagnosis of keratoconus using echography allows us to establish the phase of its progression (waxy tissue is absent in the stagnation phase). Examination with an ocular and IOL probe should be carried out under mydriasis, which does not transmit ultrasound rays, or under conditions of intense hyperemia of the cornea to identify hidden changes in the conjunctiva and sclera.
