Visual field abnormal data acquisition system

Abstract

The invention provides a universal visual field abnormal data acquisition system. Each grid line forming the grid table independently forms a spline curve based on a QtCharts drag type spline curve family, and a user can change the shape of each spline curve by moving the position of a control point on the spline curve through human-computer interaction, so as to enable the whole Amsler grid table to become a dynamic area for accurately editing the shape and color of each part; the dynamic area takes the lower left corner as a coordinate origin, the right direction is an x-axis positive direction, and the upward direction is a y-axis positive direction; a plurality of control points are arranged on the grid lines at equal intervals, a user controls movement through a point-by-point direction key, the control points of the grid lines can move in any direction, and the control points move by a fixed step pitch in a single time; the positions of the control points are changed in the mode that the mouse is pressed down and dragged, and the control points of the grid lines can move in any direction.

Description

technical field [0001] The present application relates to the field of data collection, and in particular, to a data collection system for abnormal visual field. Background technique [0002] The macula is located in the center of the retina and is the most sensitive area of ​​human vision. This area is distributed with a large number of cone cells responsible for vision and color vision. Therefore, any lesions involving the macula will cause a significant decrease in central vision, dark colors, and deformation. With the increase of the average age of the population in my country and the popular use of various electronic products, the degeneration of the macular has rapidly become a "blind killer" that seriously affects vision. As of 2020, the number of patients with macular degeneration in the world has reached nearly 200 million, and this number is still showing a rapid upward trend. The symptoms of age-related macular degeneration are similar to those of presbyopia, but...

Problems solved by technology

This type of software focuses on solving the visual field defect measurement function, but this alone is far from enough for the condition assessment of patients with macular degeneration

[0012] Although some of the above software are called "electronic Amsler tables", they are actually limited to using the Asmler table as a background reference for drawing functions and moving the drawing board from the paper to the screen. However, it is still necessary to manually draw curves throughout the process, which is not fundamental. It does not have great practical application value to solve various cumulative errors caused by problems such as insufficient manual precision, too random shape of the drawn curve, and movement of the line of sight whe...
