In our world of information overload, there is an increasing struggle to keep the main thing the main thing. Fundamental OSCE Guide in Ophthalmology is a concise study guide presented in a direct, exam style question and answer format, illustrated with high quality clinically relevant photographs tailored to medical students, nurses, optometrists and residents in their early ophthalmology training.

This book provides invaluable guidance to readers in presenting their answers in a logical, succinct and elegant manner. The style and format have been intentionally designed to simulate examination conditions and to provide readers with ample practice in preparation for the examinations.

Ophthalmology is a very specialized field with many textbooks providing a wealth of information. Exposure to ophthalmology is limited in most undergraduate interactions to a few weeks at best. With a shortage of time, gaining a good understanding of what is important is overwhelming. This book helps to streamline and focus knowledge of readers in understanding the essential conditions in ophthalmology.

Various other texts on ophthalmology are often in prose and covers a wide range of topics, including the esoteric conditions. To the untrained eye, it is difficult to discern what should be focused on. Students are often times excited about knowing rare conditions and spend precious time and effort remembering details of these conditions without a strong foundation of the more common conditions seen day to day. This books not only highlights the important conditions, it is structured to simulate examination conditions and can be used as a self-testing tool.
