Abstract
Disclosed herein are system and method for testing and analysis of visual acuity and changes using an acuity model, the acuity model generated based on one or more acuity chart design parameters and candidate acuity parameters calculated using the acuity test data of the subject, the acuity model comprising a chart-specific psychometric function determined using a family of multiple-optotype psychometric functions, and wherein the acuity model is configurable to estimate possibility of obtaining the acuity test data of the subject.
Claims20
A computer-implemented method for evaluating visual acuity of a subject, comprising:
- a) obtaining one or more acuity chart design parameters;
- b) collecting acuity test data of the subject;
- c) generating one or more sets of candidate acuity parameters based on the acuity test data of the subject, each of the one or more sets of candidate acuity parameters comprises a rank obtained by analyzing the acuity test data of the subject;
- d) generating a plurality of candidate acuity charts based on the one or more acuity chart design parameters;
- e) ranking the plurality of candidate acuity charts based on the rank of each of the one or more sets of candidate acuity parameters;
- and
- f) selecting one or more acuity charts from the plurality of candidate acuity charts based on ranks thereof to be presented to the subject for acuity testing.
A computer-implemented method for interactively evaluating visual acuity of a subject, the method comprising:
- a) obtaining one or more acuity chart design parameters;
- b) collecting acuity test data of the subject;
- c) generating one or more sets of candidate acuity parameters based on the acuity test data of the subject, each of the one or more sets of candidate acuity parameters comprises a rank obtained by analyzing the acuity test data of the subject;
- d) generating a plurality of candidate acuity charts based on the one or more acuity chart design parameters;
- e) ranking the plurality of candidate acuity charts based on the rank of each of the one or more sets of candidate acuity parameters;
- and
- f) selecting one or more acuity charts from the plurality of candidate acuity charts based on ranks thereof to be presented to the subject for acuity testing.
