The optic disk, or optic nerve head, is a critical part of the eye's anatomy that connects the retina to the brain. This area contains the optic nerve fibres that transmit visual information from the retina to the brain, which allows us to see. Some synonyms for the optic disk include optic disc, papilla, or optic nerve head. Certain medical conditions like optic disc edema can affect this area and cause vision problems. Therefore, it is essential to take good care of our eyes and visit an eye doctor regularly to prevent any vision complications.
