Ophthalmology is a medical specialty that deals with the anatomy, physiology, and diseases of the eye and the visual system. Physicians in this field, known as ophthalmologists, provide medical and surgical care for a wide range of eye conditions, from refractive errors to complex diseases such as glaucoma and retinal disorders. The aim is to preserve vision, treat injury, correct deformities, and restore function when possible. Ophthalmology intersects with optometry and other medical disciplines to coordinate care for patients of all ages.

Assessment typically begins with history and external examination, followed by specialized tests such as slit-lamp biomicroscopy, indirect ophthalmoscopy, tonometry to measure intraocular pressure, visual field testing, and imaging modalities like optical coherence tomography or ultrasound.

Common conditions include refractive errors, cataract, glaucoma, age-related macular degeneration, diabetic retinopathy, corneal diseases, conjunctivitis, and optic neuropathies. Treatments range from corrective lenses and medications to laser therapy and surgical procedures such as cataract extraction, refractive surgery (e.g., LASIK), glaucoma filtering surgery, vitrectomy, and corneal transplantation.

Training involves medical school, a residency in ophthalmology, and often fellowships in subspecialties such as retina, cornea, glaucoma, pediatric ophthalmology, neuro-ophthalmology, and oculoplastic surgery. Ophthalmology is a global health priority because vision loss is a major cause of disability, especially in low-resource settings. Organizations such as the American Academy of Ophthalmology and international health groups promote standards of care and research.
