Abstract

Metamorphopsia, commonly referred to as distorted vision, is a serious visual impairment which remains uncorrectable by optical glasses or contact lenses. This paper presents a novel approach to digitally map visual distortion based on patient feedback. The approach is based on the use of low-level geometrical constraints (central symmetry) which provide a simple and intuitive mechanism for a patient to provide feedback on their perceived visual distortion. We derive a set of fundamental constraints and show how visual distortion mapping can be framed as an optimisation problem. Critically, a parametric distortion model based on MLS is used to reduce the dimensionality of the problem and enable detailed visual distortion estimation. An extensive evaluation using simulated data demonstrates the accuracy and robustness of the approach. This approach opens up the possibility of correcting for visual distortion by applying the inverse mapping on the input stream to for instance VR see-through devices or screen-based devices.
