About this topic

Ocular Toxicology examines the effects of chemical and physical agents on the eye, a sensitive and complex organ. This topic details eye anatomy and physiology, protective mechanisms, and the specific toxic effects of various agents. Zambian university students in medicine, optometry, pharmacology, and industrial hygiene will learn about chemical burns from acids and alkalies, irritant effects of solvents and detergents, cataract formation, retinopathies, and neurotoxic blindness. Understanding the mechanisms of injury, such as corneal opacity, impaired pupillary response, and damage to the lens or retina, is essential for diagnosis and emergency management. Proficiency in ocular toxicology is vital for success in tertiary examinations and for future professional practice in clinical toxicology, occupational safety, and public health interventions within Zambia.
