This photograph depicts the in depth, severe approach in a dilated eye examination. The special drops have expanded the pupil of the patient and this enables the optometrist to shine a light on the patient and be able to see the inside back of the eye which is called the retina. It is a preventive health practise that is considered to be a basic action but achieves a lot because ocular illnesses such as glaucoma, macular degeneration, and diabetic retinopathy are identified way before the emergence of symptoms. Notably, it may also indicate revealing symptoms of such conditions of the body as high blood pressure or some neurological disorders. The microscopic image of the blood vessels of the retina, optic nerve and tissue furnishes a unique perspective on the overall wellness of the eye and the entire body highlighting the point that there is much more involved with a complex examination than a clear vision.
