Problems solved by technology

However, there is a problem in the prior art metamorphopsia measurement using the Amsler grid that the distance between the lines of the Amsler grid is fixedly determined in advance, and the patient has his / her own metamorphopsia, but cannot quantify the degree of metamorphopsia
Although the degree of metamorphopsia can be quantitatively evaluated to a certain extent by M-CHART, only the degree of metamorphopsia in the center is measured, and there is still a problem in the results, that is, the occurrence of metamorphopsia in the outer visual field outside the center cannot be reflected. scope

Embodiment Construction

[0038] A method for determining metamorphopsia based on user interaction according to an embodiment of the present invention may include: displaying a test chart to a user; receiving a user display input for displaying at least one metamorphic region relative to the displayed test chart ; Displaying the test chart while adjusting the distances of multiple points in the at least one metamorphic region displayed based on the received user display input by applying a point distance adjustment signal from the user; In the case of metamorphosis, obtain the distance values ​​of multiple points in the at least one metamorphic region and the area value of the metamorphic region, and the user receives in a display portion other than the displayed at least one metamorphic region Repeat the previous steps if there is still a user input of the metamorphic area, and determine the user's visual field based on the acquired distance value and area value of the point in the case that there is n...

Abstract

As an embodiment of the present invention, The present invention discloses a method for determining metamorphopsia on the basis of a user interaction, wherein a test chart is displayed to a user, an input for a part on the displayed test chart that appears distorted is received from the user, and the degree of metamorphopsia of the user can be accurately determined on the basis of the area of distortion selected according to the received input. In addition, according to another embodiment of the present invention, a test chart is displayed to a user, a response for each sector of the test chart (for example, the distance between points of a metamorphopsia region in a corresponding sector, the area of a metamorphopsia region in a corresponding sector, etc.) is received from the user, and whether the user suffers from metamorphopsia can be determined on the basis of the received response.

Description

technical field [0001] The present invention relates to methods and apparatus for determining metamorphopsia based on user interaction, and more particularly to methods for classifying the degree of metamorphopsia based on the area of ​​the metamorphopsia region from user input relative to test chart input A method and apparatus for determining metamorphopsia and indicating thereby. Background technique [0002] Anamorphic refers to a state in which an object appears distorted or deformed. In other words, anamorphia is a condition in which a straight lattice pattern appears distorted in a wavy shape or crumpled and twisted. [0003] Metamorphopsia may be caused by diseases such as abnormalities of the choriochoriomacular surface of the macula such as epiretinal macular holes and macular degeneration or central serous chorioretinopathy. In other words, the structure of the eye that acts like a camera film (i.e., the image is focused on the eye) is the retina, and in the ret...
