Mathematical models to describe fixation disparity curves.

ABSTRACT:

Purpose

This study developed mathematical models to describe the four classical types of Fixation Disparity Curves (FDCs), addressing the limitations of existing generalised polynomial fits. These models provide an objective framework for analysing FDCs, with the goal of improving the diagnosis and management of binocular vision disorders.

Methods

The study was conducted in two phases. In the first phase, elementary mathematical functions were identified for each type of FDC: a polynomial function for Type I, an exponential function for Types II and III and a trigonometric function for Type IV. The function parameters were optimised using the least squares method in MATLAB. In the second phase, the models were validated using experimental data from 20 participants to ensure
