Description

Ophthalmology is a branch of medicine dealing with the diagnosis, treatment and prevention of diseases of the eye and visual system. An ophthalmologist is a medically trained doctor who commonly acts as both a physician and surgeon. Trachoma is a chronic keratoconjunctivitis caused by four ocular serotypes A, B, Ba and C of organism Chlamydia trachomatis. It is a disease of underprivileged populations living in poor conditions of hygiene. The pathway linking late-life malnutrition to greater risk of cardiovascular disease is unclear. Microcirculatory changes assessed by retinal vascular caliber have been linked with increased risk of stroke and coronary heart disease. The purpose of this study was to examine whether retinal vascular calibers are associated with malnutrition in elderly subjects free of cardiovascular diseases. In the discipline of Community Ophthalmology, the new cadre of personnel known as eye health care workers, eye health care educators or ophthalmic assistants are trained to provide eye care and blindness prevention services at the village or door-to-door level. This book provides the basic clinical knowledge of Ophthalmology to undergraduate students. It describes all the basic aspects that are important for a beginner and highlights the Tropical ophthalmic diseases besides trachoma, malnutrition, and community ophthalmology.
