Ophthalmological (eye) examination

An ophthalmological exam aims to test the patient's ability to see, determine the level of visual acuity in each eye, and find any eye conditions that affect eye health, such as cataracts, glaucoma, diabetic retinopathy, macular degeneration, etc. The ophthalmologist asks about the patient's medical history, current medications, and symptoms. Then, the doctor does a "visual acuity" test to see how well and sharply the patient can see. During a slit-lamp exam, the doctor looks at the front part of the eye, such as the eyelids, cornea, iris, and lens. The way the pupils react to light is used to figure out how well the optic nerve is working. During tonometry, the intraocular pressure is measured. The refraction test tells if a person needs glasses or contacts by selecting the proper lens power to correct issues. An ocular motility exam checks how the eyes move and work together. The visual field test measures the peripheral sight. The dilated fundus exam looks at the back of the eye, including the blood vessels, retina, and optic nerve. Regular checkups help find and treat eye diseases early, maintain good vision and eye health, track changes, and determine if you need to correct vision.
