Echobiometry

Echobiometry is an ultrasound diagnostic method used to measure the dimensions of the eyeball, detect pathological changes in its internal structures, and assess the condition of the vitreous body. The examination is widely applied in ophthalmology for the diagnosis of cataract, glaucoma, high myopia, and as part of preoperative eye assessment.

When is echobiometry indicated?

• Preoperative assessment before cataract surgery (calculation of intraocular lens parameters).
• Measurement of axial eye length in myopia and hyperopia.
• Suspected glaucoma, intraocular tumors, or retinal detachment.
• Diagnosis of vitreous body pathologies (hemorrhage, vitreous detachment).
• Eye trauma to evaluate damage to internal ocular structures.

How is the examination performed?

1. A special gel is applied to the eye to improve ultrasound signal transmission.
2. An ultrasound probe is directed at the eye, and sound waves transmit information about ocular structures.
3. The device automatically analyzes the dimensions of the eyeball and generates measurement results.
4. The physician interprets the data and evaluates possible abnormalities.

Types of echobiometry

• Contact echobiometry. The probe touches the eyelid or the surface of the eye.
• Non-contact echobiometry. Used when direct contact with the eye is contraindicated.

Which conditions can be detected by echobiometry?

• Cataract (structural changes of the crystalline lens).
• Glaucoma (assessment of changes in the anterior chamber of the eye).
• High myopia (increased axial length of the eyeball).
• Retinal detachment and vitreous body abnormalities.
• Intraocular tumors and space-occupying lesions.

Advantages of echobiometry in Belarus

• Painless and safe diagnostic procedure.
• High measurement accuracy.
• No extensive preparation required.
• Suitable for diagnosing a wide range of ophthalmic conditions.

In Belarus, echobiometry is performed in modern ophthalmology clinics equipped with next-generation ultrasound scanners. This method provides precise ocular measurements, which is particularly important in preparation for surgical eye treatment.
