Problems solved by technology

[0003] GAT-based intraocular pressure measurement methods need to sensitively detect the small force that deforms the cornea and obtain accurate corneal applanation area, but so far, there is no correlation of methods that simultaneously address these two requirements in the intraocular pressure measurement experiment. to report

Abstract

The invention discloses a device combining a sensor and the SS-OCT technology to test intraocular pressure. The device comprises the sensor, optical coherence tomography equipment and a linear platform and is characterized in that the sensor is arranged right above to-be-tested eyeballs, the to-be-tested eyeballs are placed on the linear platform, the linear platform drives the to-be-tested eyeballs to move forwards and backwards to regulate the distance between the eyeballs and the sensor; the optical coherence tomography equipment comprises a scanning lens, and the corneas of the to-be-tested eyeballs are regulated to the focal length of the scanning lens during testing. The device has the advantages that nondestructive high intraocular pressure detection is achieved, and the sensor is high in sensitivity; compared with a traditional method, the device can detect micro-force allowing the corneas to deform and acquire precise cornea applanation area and is more accurate.

Description

technical field [0001] The invention belongs to the field of medical image detection, and in particular relates to a device and application for testing intraocular pressure combined with a sensor and OCT technology. Background technique [0002] High intraocular pressure (IOP) has been shown to be one of the major risk factors for glaucoma. Accurate IOP is important when treating patients with ocular hypertension and glaucoma, especially those undergoing eye surgery. Currently, the most reliable and widely accepted method for measuring IOP is Goldmann's applanation tonometry (GAT). The rationale for GAT relies on the Imbert-Fick law, in which the force on the applanated corneal surface is equal to the product of the true IOP (IOPT) of the corneal surface and the applanated area. Optical coherence tomography (OCT) is a new real-time, fast, high-resolution, non-invasive biomedical imaging technique developed in the early 1990s. It is widely used to obtain non-invasive real-...
