The Daroff-Dell'Osso Ocular Motility Laboratory
(OMLAB)

An Endowed Laboratory of CASE School of Medicine and Case Western Reserve University
Located in the Louis Stokes Cleveland Department of Veterans Affairs Medical Center
Cleveland, Ohio, USA

Measurement of Human Eye Movements to Study Neurological, Visual, and Vestibular Disorders; Ocular Motor System Function and Dysfunction

Areas of Specialization: Systems and Computational Neurobiology, Ocular Motor Oscillations (Nystagmus and Saccadic), Ocular Motor System Models, Nystagmus Therapies, Vision and Balance, Vestibular Function, Version-Vergence Interaction, Eye-Head Interactions, and Retinal Electrophysiology of Visual Disorders
Measurement techniques: Infrared Reflection, Magnetic Search Coil, and High-Speed Digital Video Systems to record eye movements in the horizontal, vertical and torsional planes of humans; Motion Platform and Rotating Chairs to study balance.
Off-Site Research: Because the Daroff-Dell'Osso Ocular Motility Laboratory is designed for the study of human eye movements only, any non-human studies, e.g., on canines [COMLAB] and mice, have been carried out by specific investigators at other facilities in collaboration with investigators based at those facilities.

UPDATES
OMtools has undergone major revisions. It has been thoroughly modernized to work with current and recent MATLAB versions, and is easier to install and configure. It can now import Eyelink EDF files (with free download of SR-Research's developer kit for Mac, Linux, or Windows). Check back for regular updates.

DD_OMLAB Dissertations available for download: PDFs of the PhD Dissertations of LF Dell'Osso, JB Jacobs, and ZI Wang. These contain the first OMS models to simulate normal function and both INS and FMNS.

DD_OMLAB Data! 557 de-identified and digitized eye-movement data sets from all of the 347 subjects recorded in our lab from 1986 to 2013 are now available for research and study.
Data recorded elsewhere will soon be added.
