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

The software and models listed here were originally written in MATLAB 5.2.x and Simulink 2.x, under Mac OS 9. The software (but not the models) has been tested in MATLAB 6 and 7 under Mac OS X, and no "show stoppers" have been found. There may be some cosmetic issues, or MATLAB/Simulink may respond with a flurry of non-fatal warnings. Type "warning off" at the command line to suppress them.

OMLAB 'OMtools' Software:
'OMtools' is a set of programs (m-files) and figures, arranged in heirarchical folders (directories), that were written to aid in ocular motor data retrieval, analysis, and display. NOTE: Some programs require the MATLAB Signal Processing Toolbox.
For questions regarding the use of (or problems -- unpossible! -- with) specific m-files, email Dr. Jacobs at jxj24 (at) case (dot) edu.

The eXpanded Nystagmus Acuity Function (NAFX) is a fuction that uses relevant nystagmus parameters to predict the best possible visual acuity for a given set of nystagmus data based on the presumption that no afferent deficits are present. To the extent that the latter are present, the measured acuity will fall below the potential acuity. Once both acuity and nystagmus data are measured, the NAFX can also be used to estimate the improvement in measured acuity subsequent to therapy. For questions regarding the use or interpretation of the NAFX in specific cases, email Dr. Dell'Osso at lfd (at) case (dot) edu or Dr. Jacobs at jxj24 (at) case (dot) edu.
NOTE: NAFX is part of the 'OMtools' distribution, available through the above link.)

OMLAB OMS Models:
The Ocular Motor System model is a functional, behavioral ocular motor model capable of simulating ocular motor responses to specific target stimuli. It simulates the responses of normals and those with a variety of disorders including congenital, latent/manifest latent, and gaze-evoked nystagmus, vaious types of saccadic intrusions and oscillations, and ocular myasthenia.
For questions or suggestions regarding the use or expansion of this model, email Dr. Dell'Osso at lfd (at) case (dot) edu or Dr. Jacobs at jxj24 (at) case (dot) edu.
