perométrie

Perométrie is a specialized field of ophthalmology that focuses on the measurement and analysis of the eye's refractive state. It involves the use of advanced instruments and techniques to determine the eye's refractive error, which is the degree to which light is bent as it passes through the eye. This information is crucial for diagnosing and treating refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.

The primary instrument used in perometry is the autorefractor, a device that projects a series of light patterns onto the eye and measures the angle of reflection to calculate the refractive error. This non-invasive method allows for quick and accurate assessments of the eye's refractive state.

Perometry is essential in various clinical settings, including optometry, ophthalmology, and vision therapy. It plays a critical role in the diagnosis and management of refractive errors, helping to determine the appropriate corrective lenses or surgical procedures. Additionally, perometry is used in research to study the development and progression of refractive errors and to evaluate the effectiveness of new treatments.

In summary, perométrie is a vital tool in the field of ophthalmology, providing precise measurements of the eye's refractive state to aid in the diagnosis and treatment of refractive errors. Its non-invasive nature and accuracy make it an indispensable technique in both clinical practice and research.
