Automatic recording and processing of saccadic electrooculograms.

Abstract

This work presents the development of a technology that processes human eye movement records in a fully automatic way. Since it is part of a collaboration with the Center for Rehabilitation and Research of Hereditary Ataxias (CIRAH) of Cuba, we focus on records of subjects suffering Spinocerebellar Ataxia type 2 (SCA2). Our research has two complementary objectives: (i) design a fully automatic method to extract the relevant medical data from saccadic eye movement recordings; (ii) design and testing a low-cost device to record eye movements for clinical purposes. To accomplish the first goal, we have defined a processing pipeline which comprises the following blocks: filtering, differentiation, segmentation and biomarkers extraction.
