What Is Ophthalmology?
Ophthalmology is the branch of medicine that focuses on the diagnosis and treatment of eye disorders and diseases. Whereas optometrists perform routine eye exams and prescribe corrective lenses, our ophthalmologists are experts in all areas of eye care and licensed to address a wide range of eye conditions, such as:
- Cataracts: A visual impairment that clouds the eye’s natural lens and is the leading cause of blindness
- Cornea and external eye diseases: Conditions include dry eyes, blepharitis, keratoconus, Fuchs’ endothelial dystrophy, and bullous keratopathy
- Glaucoma: This disease causes damage to the optic nerve and can cause visual impairments or blindness
- Retinal pathology: Includes diabetes, floaters, macular degeneration (dry and wet), and retinal tears
- Strabismus: More commonly known as lazy eye, strabismus forces the brain to favor one eye
- Inflammatory eye conditions: A variety of eye problems arising from autoimmune or inflammatory disorders, as well as infections
