Advances in Ocular Imaging

Ocular imaging is a technology that allows quantitative examination of the posterior segment of the eye. This is a diagnostic tool that helps detect changes in the optic nerve head (ONH), the nerve fiber layer (NFL), and the macula. Such changes may be associated with glaucoma. Ocular imaging devices play a pivotal role in clinical glaucoma assessment due to their ability to obtain micron scale measurements. There are three major devices for ocular diagnostic imaging, namely, scanning laser polarimetry (SLP), confocal scanning laser ophthalmoscopy (CSLO), and optical coherence tomography (OCT). The real-time, non-invasive, and high-resolution images of the eye are provided by all three devices. The first technology, SLP, is used to determine the thickness of the nerve by assessing the birefringence of polarized light as it is reflected from the eye. The second technology, CSLO, is a confocal microscopy technique that has high transverse resolution. This book is compiled in such a manner, that it will provide in-depth knowledge about the theory and practice of ocular imaging. It is appropriate for students seeking detailed information in this area as well as for experts.
