Abstract

The invention discloses a system for determining an intraocular pressure of a subject. The system comprises a pressurizing device, a monitoring device and a processing unit, the pressurizing device is used for applying different pressures on the outer surface of an eye of the main body; the monitoring device is used for monitoring the internal vasculature of the eye and the vasculature on or around the eye; the processing unit is configured to associate a first pressure or pressure range having a pulsation or collapse of the internal vasculature of the eye with a second pressure or pressure range having a pulsation or collapse of the vasculature, thereby deriving the intraocular pressure of the subject.

Description

technical field [0001] The present invention generally relates to systems for determining intraocular pressure. Embodiments of the present invention relate to portable tonometers that can be used by the subject himself or by an operator in a non-clinical setting. Background technique [0002] Intra-ocular pressure (IOP) measurement is an important procedure for diagnosing various ocular diseases and abnormalities and monitoring the status of ophthalmic treatments and procedures. [0003] Intraocular pressure is measured by a device called a tonometer. Traditional stationary tonometers are cumbersome and entrusted to medical offices, require special training and are limited to testing intraocular pressure when the patient is in an upright position. [0004] Some tonometers require eye contact, are more complex, and may require the use of sterile disposable components. [0005] Intraocular pressure measured in different subject positions can sometimes result in different re...
