Embodiment

[0022] A method for measuring exophthalmos is characterized in that laser light is used to measure the distances between the laser light source and the vertex of the cornea, and the distance between the laser light source and the outer orbital rim, and the difference between the two distances is the exophthalmos.

[0023] Such as figure 1 Shown, a kind of laser exophthalmos measuring instrument is made up of bracket 1 and operating platform 11, and described operating platform 11 is provided with horizontally movable platform 9, and described horizontally movable platform 9 is provided with laser measuring instrument 5, through adjustment operation The rod 8 realizes the horizontal movement of the horizontal movement platform 9, and then enables the laser measuring instrument 5 to move horizontally on the operating platform. The operating table 11 may be an operating table commonly used in ophthalmology in the prior art.

[0024] The bracket 1 is provided with an outer orbita...

Abstract

The invention provides a measurement method of expophthalmos, which realizes the purpose that the distance between a laser source and the top end of cornea and the distance between the laser source and a lateral orbital margin can be measured respectively by utilizing laser, and the two distances are the expophthalmos. The invention also provides a laser exophthalmometer for realizing the measurement method and application of the exophthalmometer. According to the invention, the influences of optical parallax and other factors and influences of different examiners and lateral orbital margin fracture or skin swelling can be eliminated, the exophthalmos can be accurately measured relatively, and quantitative measurement can be performed on up and down displacement of globe.

Description

technical field [0001] The invention relates to the field of ophthalmological examination, in particular to a method, instrument and instrument application for measuring exophthalmos. Background technique [0002] The prior art mainly uses an exophthalmos meter to measure the protruding amount of the eyeball relative to the outer orbital rim by visually observing that the scale line coincides with the corneal apex. The main disadvantages are as follows: 1. Different examiners lead to different measurement results. Even if the same examiner examines the same patient at different times, the results will be different; 2. When there is a fracture of the outer orbital rim, or The results are inaccurate when the skin is swollen. [0003] Therefore, we need a measurement method and instrument that can measure exophthalmos relatively accurately and is not affected by different examiners and lateral orbital rim fracture or skin swelling. Contents of the invention [0004] The pur...
