A visual field abnormality data acquisition system

Abstract

The present invention provides a universal data collection system for visual field anomalies. Based on the drag-and-drop spline curve family of QtCharts, each grid line forming a grid table constitutes a spline curve independently. Users can move the sample curve through human-computer interaction. The position of the control point on the spline curve can change the shape of each spline curve, making the entire Amsler grid form a dynamic area for accurately editing the shape and color of each part; the dynamic area uses its lower left corner as the coordinate origin, and the right direction is the positive x axis Direction, upward is the positive direction of the y-axis; multiple control points are set on the grid line, and these control points are arranged on the grid line at equal intervals, and the user controls the movement by point-by-point direction keys: grid line control The points can be moved in any direction, and the control point can be moved with a fixed step at a time; the position of the control point can be changed by pressing and dragging the mouse: the control points of the grid line can be moved 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 macular area is located in the center of the retina and is the most sensitive area of ​​human eyesight. There are a large number of cone cells responsible for vision and color vision distributed in this area. Therefore, any lesion involving the macular area will cause a significant decrease in central vision, dark vision, and deformation. With the increase in the average age of our population and the popularization and use of various electronic products, macular degeneration 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 very similar to those of presbyo...

AI Technical Summary

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 when drawing.

In the blind spot measurement software, the marking patterns used are too single (mostly squares with a fixed size), and it is impossible to adjust the size of the marking patterns immediately and quickly, and the blind spots need to be drawn on the map before each marking for the patient to judge Is the area and size of the blind spot correct? If it is not correct, all the drawn patterns will be erased with one click, which will also erase the correct pattern, which causes great inconvenience and wastes time.

In addition, there is currently no software that integrates the functions of the above two types of software, and there is no software that uses the Amsler table to quantify and evaluate the abnormality of the patient's visual field
