of knowledge on the underlying mechanisms of hereditary eye disease. The field of ocular genetics is becoming an increasingly relevant part of ophthalmologists' purview. This has resulted in a dire need for a comprehensive textbook ophthalmologists and other professionals who work with patients with genetic disorders can utilize to gain a better understanding of inherited eye disorders. The Wills Eye Handbook of Ocular Genetics, by Alex Levin, Mario Zanolli, and Jenina Capasso of Wills Eye Hospital, is a practical, reader-friendly guide on the diagnosis and management of ophthalmic genetic conditions. Every chapter begins with a disease overview, followed by relevant modern genetic concepts, pathways to attaining the correct diagnosis, and pitfalls and pearls gleaned from years of hands-on expertise. At the end of each chapter, questions and answers enable readers to test their knowledge in real-life scenarios they might face in everyday practice.
