Ophthalmotonometry is a diagnostic procedure that helps us assess intraocular pressure and promptly detect deviations that are important for preserving vision.
Measuring intraocular pressure is necessary for glaucoma prevention and when monitoring at-risk patients.
At K31 in Moscow, patients receive not just information, but a clear explanation of the results and an answer to the question of when to return for a follow-up vision check.
Routine eye tonometry is necessary for people over 40, even if there are no complaints. With age, the risk of ophthalmological diseases increases, and early detection of changes helps to choose timely monitoring or treatment.
We recommend the procedure as part of a preventive examination, especially if there is a family history of glaucoma, myopia, diabetes, hypertension, or vascular disorders.
The doctor monitors the patient's progress: how the indicators have changed, whether there have been any fluctuations, how the patient is tolerating the therapy, and whether vision control is being maintained.
In glaucoma, we often supplement tonometry with assessment of the optic nerve, visual field, and other vision diagnostic methods.
Who should be examined?
If symptoms appear suddenly, or if there is severe pain, severe redness, nausea, sudden deterioration in vision, or an eye injury, you should seek immediate medical attention. to the doctor, rather than waiting for a scheduled appointment.
Non-contact tonometry is performed without touching the surface of the eye. The device directs a short stream of air onto the cornea and calculates the reading based on its response.
This option is convenient for screening, preventive visits, and situations where it is important to quickly obtain preliminary data. If the doctor detects abnormalities or a high risk of glaucoma, they may prescribe a repeat measurement or another method.
Contact tonometry involves gentle contact of the measuring element with the surface of the eye. Local anesthetic drops are usually used before the procedure, so there shouldn't be any significant pain.
We consider the condition of the cornea, the presence of inflammation, previous surgeries, and the patient's complaints to ensure a safe procedure.
The Maklakov method is a classic inspection method that has been used in ophthalmological practice for many years. It is a contact method and requires eye preparation, sterility, and proper evaluation of the resulting impression.
The main differences between the methods can be conveniently compared in the table:
| Method | Eye contact | Comfort | When used |
|---|---|---|---|
| Non-contact tonometry | No | High | For rapid screening and initial assessment |
| Contact tonometry | Yes | Average | When a more precise assessment is needed based on readings |
| Maklakov Method | Yes | Average | Classical Method of Monitoring Intraocular Pressure |

What is ophthalmotonometry and why do we perform it?
This method measures the pressure exerted by the intraocular fluid on the eye's membrane. This value can fluctuate throughout the day and depend on corneal conditions, age, medications, vascular conditions, heredity, and concomitant diseases.
Intraocular pressure may not cause significant symptoms for a long time. A person may see normally, feel no pain, and notice no changes, yet still be at risk for glaucoma.
However, a single result does not constitute a diagnosis. The ophthalmologist evaluates these values along with the condition of the optic nerve, complaints, examination data, corneal thickness, and other tests, if needed.
