indentationtonometria

Indentationtonometria is a specialized diagnostic technique used primarily in ophthalmology to measure intraocular pressure (IOP) within the eye. Unlike traditional tonometry methods, such as applanation or rebound tonometry, indentationtonometria relies on the principle of indentation—a controlled deformation of the cornea—to estimate IOP. This method is particularly useful in certain clinical scenarios where standard tonometry may be less practical or accurate.

The procedure involves applying a calibrated probe to the cornea, which gently indents the eye’s surface. The force required to achieve a specific indentation depth correlates with the IOP, allowing for an indirect measurement. Indentationtonometria is often employed in pediatric ophthalmology or when examining patients with corneal abnormalities, as it minimizes direct contact stress and reduces discomfort.

Historically, indentationtonometry was developed as an alternative to Schiøtz tonometry, which relied on a weighted plunger. While less common today due to advancements in electronic tonometry, indentationtonometry remains relevant in specific clinical settings. Its simplicity and adaptability make it a valuable tool in certain diagnostic workflows, particularly when precision and patient comfort are priorities.

The accuracy of indentationtonometry depends on proper calibration and technique, as variations in corneal rigidity or probe pressure can influence results. It is typically performed by trained ophthalmologists or optometrists as part of a comprehensive eye examination. While modern devices have largely replaced manual indentation methods, the principle continues to inform the design of newer diagnostic tools.
