Lacrimal river detection device and data treatment device

Abstract

The invention discloses a lacrimal river detection method and device thereof, a data treatment device, wherein the lacrimal river detection device comprises a coherent light fault scanner for detecting lacrimal river to obtain the lacrimal river section profile of preset mode; a data treatment device connected with the coherent light fault scanner, using the preset lacrimal river section profile feature result to match with the obtained lacrimal river section profile and the matching result is obtained to identify the dividing line between the lacrimal film outer surface and the air and the intersection point of the cornea and lower eyelid and the dividing line and the length between the dividing line and the connection point of the cornea and the lower eyelid is the lacrimal river heightand the distance between the intersection point of the cornea and the lower eyelid and the midpoint of the dividing line is the lacrimal river depth, the lacrimal river height and depth are respectively identified whether in the normal lacrimal river depth and the height reference range or not and the identification result is output. The lacrimal river detection method and device thereof is a validated standardization detection method, device, which can accurately and conveniently obtain the lacrimal river detection result.

Description

technical field [0001] The invention relates to the medical field, in particular to tear river detection equipment. Background technique [0002] The tear river is a tear band accumulated between the lower eyelid of the anterior segment and the cornea and conjunctiva. In ophthalmology, it is often necessary to test the tear river to confirm whether there are symptoms such as dry eye. The traditional tear river detection method is to use equipment such as slit lamps for inspection, but this method is often invasive and has poor repeatability, which affects the accuracy of the inspection. [0003] Optical coherence tomography (OCT) is a common device used to scan the fundus and anterior segment tissue. It has the characteristics of non-invasiveness and precise imaging. Therefore, in 2006, a foreign magazine (Savini G, Barboni P, Zanini M. Tear meniscusevaluation by optical coherence tomography. Ophthalmic SurgLasers Imaging. 2006, 37: 112-118.) reported that the OCT device (...

Problems solved by technology

Due to the need to go through image scaling and other processing operations, the method is cumbersome and may have a certain impact on the accuracy of the measurement; at the same time, the above-mentioned existing technology for tear river detection using OCT has not made any guarantees for the reliability and accuracy of this method. It is not suitable for clinical use; in addition, the parameters measured by the above-mentioned prior art only include height and depth values, which is not conducive to further application in clinical and scientific research.
