Aberrometry: Clinical and Research Applications

Aberrometry: clinical and research applications.

O ptometry has a history of taking the lead in correcting the optical defects of the eye. While the primary definition of optometry has changed as the profession has expanded its scope of practice, the secondary definition of optometry has remained unchanged. The second definition of optometry is the use of an optometer. The definition of optometer is any of several objective or subjective devi...

Aberrometry: basic science and clinical applications.

This paper addresses the concept, measurement and applications of wave aberrations. The ocular optics is not perfect. Apart from conventional low order aberrations (such as defocus and astigmatism) retinal images are degraded by other high order aberrations. Aberrometers typically measure ray deviations at the retinal plane, as a function of pupil position, i.e. local derivatives of the wave ab...

fMRI: Clinical and Research Applications

In the last century many researchers have tried to discover the secrets involved in the function of the brain. While the old view about the brain operations was based on the principle of mass action [1], using the new techniques for example using the functional neuroimaging experiments, it has been shown that the structure and the function of the brain are correlated together. Modern neuroimagi...

Multimodality neuroimaging: research and clinical applications.

This manuscript reviews the current stance and the pertinent problems of transcranial magnetic stimulation (TMS) and functional magnetic resonance imaging (fMRI) as brain mapping methodologies. The missing structure-function relation limits the use of TMS, whereas the uncertainty about the functional significance of activated cortical regions might render interpretation of fMRI studies difficul...
