Ophthalmosphygmography

Ophthalmic phygmagraphy is a new method for examining ocular and tear duct function that uses signal processing from a photopolymer located under the eye and optimized corneal properties to measure these functions.

How is ophthalmosphygmography performed? In general, the technology includes several main stages. The first stage - preparing the patient for the study is carried out by treating the eye with a solution or other substance that expands to open the internal structures of the eye, such as the tear duct for the passage of fluid and the retina. After treatment, the second stage begins, when the doctor conducts an examination by placing optoelectronic capsules under the patient's upper eyelid or eyeball using microsurgical instruments. The capsule replaces the eye's tears, providing a constant flow of condensation and preventing image narrowing. During the test, the patient continues to work, trying not to blink. The images collected by the camera are captured on video and processed to identify objects that the doctor can advise the patient on. The result of the study is a static or dynamic oculomotor test, containing information about such parameters as the ability to focus on close/far objects, the ability to withstand prolonged concentration, the optical power of the eye and the condition of the tear ducts.
