The sensory system plays a fundamental role in perception, communication, and interaction with the external environment through the mechanisms of vision, hearing, smell, taste, and touch. Disorders affecting this system such as Vision Disorders, Retinal Disorders, Retinoblastoma, Conjunctivitis, Pterygium, Cornea Disorders, Refractive Disorders, Hearing Disorders, Peripheral Vestibular Disorders and Vertigo often significantly affect patients’ quality of life and functional independence. Effective management requires accurate assessment, early detection, critical reasoning, and evidence based nursing interventions to prevent complications and support optimal patient outcomes. Through the material presented in this book, readers are expected to strengthen their knowledge of pathophysiology, clinical manifestations, diagnostic procedures, treatment modalities, perioperative care, and comprehensive nursing strategies grounded in holistic and patient centered approaches.
