Summary
Evaluating amblyopia treatment efficacy requires precise methods. This study introduces a new quantitative index combining visual functions, offering a more accurate measure than visual acuity alone for amblyopia rehabilitation.
Area of Science:
- Ophthalmology
- Vision Science
Background:
- Effective amblyopia treatment evaluation is crucial for prevention, control, and rehabilitation.
- Current methods may not fully capture treatment efficacy.
- Developing precise, quantitative measures is essential.
Purpose of the Study:
- To develop a more precise and quantitative method for evaluating amblyopia treatment efficacy.
- To explore the correlation between visual acuity and other visual functions post-treatment.
- To establish a comprehensive index for representing treatment outcomes.
Main Methods:
- Recorded four visual function examination results: visual acuity, binocular rivalry balance point (BRBP), perceptual eye position (PEP), and stereopsis.
- Assessed these functions before and after amblyopia treatment.
- Applied the Criteria Importance Through Inter-criteria Correlation (CRITIC) method to objectively weight and couple the four indexes.
Main Results:
- All four visual function measures showed significant differences before and after treatment.
- Visual acuity improvement did not strongly correlate with changes in BRBP, PEP, and stereopsis.
- The CRITIC-based coupled index demonstrated good performance on a validation dataset, offering a more comprehensive efficacy measure.
Conclusions:
- The proposed coupling method using the CRITIC algorithm and multiple visual function results offers a potential means to quantify amblyopia treatment efficacy.
- This approach provides a more objective and comprehensive evaluation than relying solely on visual acuity.
- The findings support the use of this novel index in clinical practice and research for amblyopia management.
