Optical coherence tomography is an imaging test which is non-invasive in nature, and makes use of light waves in order to take cross-section pictures of the retina. The different layers of the retina are visible through this technique. There are numerous eye conditions which can be diagnosed through optical coherence tomography. A few of them are glaucoma, diabetic retinopathy, macular edema and macular hole. The disorders of the optic nerve are also examined using this technique. The conditions which interfere with the passage of light through the eye cannot be diagnosed through optical coherence tomography, since it depends on light waves. This book brings forth some of the most innovative concepts and elucidates the unexplored aspects of optical coherence tomography. It strives to provide a fair idea about its clinical applications and to help develop a better understanding of the latest advances within this field. This book is a vital tool for all researching or studying ophthalmology as it gives incredible insights into emerging trends and concepts.
