Abstract
This work introduces a method to objectively and non-invasively detect subretinal fibrosis secondary to neovascular age-related macular degeneration. The method exploits the birefringent properties of fibrous tissue: the axis orientation of fibrous tissues is well-defined, whereas the axis orientation of non-fibrous tissues is random. After removal of the influences from birefringent tissues anterior to the fibrosis, fibrotic scar tissues were the only remaining areas with uniform axis orientation and therefore became distinguishable from healthy tissue. The algorithm detected fibrosis congruent to color fundus photography, which is the current gold standard to diagnose fibrosis.
