Ophthalmology is a medical specialty that deals with all facets of eye health and its vision system, including anatomy, physiology, histology, and diseases. Vision plays an important role in our daily lives. Clinical ophthalmology is a field of medicine that studies eye physiology, disorders, and treatment options. Clinical ophthalmology diagnoses and operates on eyes. Clinical procedures can diagnose a wide range of diseases and conditions of the eye. Clinical ophthalmology is primarily concerned with the research and clinical discoveries of various eye conditions, as well as the methods involved in ophthalmic patient care. It also includes investigations on ophthalmic surgical procedures, translational research, and ocular medicines, among other things. Experimental ophthalmology is ophthalmology's basic research.
