The human retina is probably the most versatile and complex tissue. Disorders involving its many layers and those of tissues adjacent to it result in varying degrees of visual impairment. Until some time ago, diagnosing such pathologies had a large subjectivity to it based largely on one's experience. In addition, certain pathologies went undetected (e.g. vitreomacular traction) or could be detected only when the pathology was firmly established. The results of treatment could also be evaluated only qualitatively and at the most semi-quantitatively.

In the book Retinal Imaging an effort has been made to familiarize the readers with various modalities of imaging currently being employed to diagnose and treat retinal diseases. The topics covered range from state-of-the art positron-emission tomographic imaging, combined OCT and angiography to more established procedures like ultrasound biomicroscopy, optical coherence tomography, fluorescein angiography and indocyanine green angiography. A separate chapter on special techniques discusses facets on fundus autofluorescence imaging, stereo-imaging and oral fluorescein angiography. The book is replete with digital images and illustrations so as to enable better understanding and assimilation of the text.

It is our hope that the book would add value to all readers practising ‘Retinology’. We would also welcome critical comments addressing any drawbacks in this endeavor and suggestions for improvement from readers of the book.
