Ophthalmologists are responsible for the diagnosis, prevention, and treatment of almost all eye conditions and visual issues. However, subspecialist ophthalmologists tend to treat and monitor certain conditions, such as: glaucoma, retinal conditions, such as macular degeneration and diabetic retinopathy, corneal conditions, cataracts, cases involving children or childhood eye conditions, cases with a neurological cause or component, such as optic nerve problems, abnormal eye movements, double vision, and some kinds of vision loss, cases involving complex surgical procedures, such as reconstructive surgery or advanced vision repair. Aside from caring for the eyes and vision, an ophthalmologist’s medical training may also equip them to notice symptoms of conditions that do not directly relate to the eye. In such cases, they can refer people for the appropriate treatment.Many ophthalmologists also participate in some form of scientific research focusing on the causes of eye and vision conditions, as well as potential cures.
