The Basic Bookshelf for Eyecare Professionals is a series that provides fundamental and advanced material with a clinical approach to clinicians and students. A special effort was made to include information needed for the certification exams in ophthalmic and optometric assisting, as well as for surgical assistants, opticians, plus low vision, and contact lens examiners. This book moves beyond basic exam skills into the arena of more advanced diagnostic testing. Topics include biometry and echography, electrophysiology, psychophysical testing, and microbiology. Special tests such as exophthalmometry, pachymetry, and ophthalmoscopy are also covered. This is the ultimate how-to book for those performing detailed patient exams.
