This is the first book that assembles both old and new techniques for evaluation of retinal and optic nerve function in eyes with cloudy media, that is of importance in prognosis and in decisions for vitreal and retinal surgery. The authors had previous training in vitreal surgery under Dr Robert Machemer, and in ultrasonic diagnosis under Drs D. Jackson Coleman and Karl Ossoinig.

The authors describe such routine evaluation as the importance of ocular and medical history and routine ocular examinations including light projection, color discrimination, Maddox Rod orientation, two-point light discrimination, Purkinje entoptic imagery, blue-field entoptic phenomenon, afferent pupillary reaction, and laser interferometry. More sophisticated tests include bright flash electroretinogram that can be used in eyes with moderately cloudy media. The a wave
