Optic nerve

The optic nerve is a bundle of over one million nerve fibers that carry visual information from the retina to the brain. It is located at the back of the eye and is responsible for transmitting images to the brain. The optic nerve is essential for vision, and damage to the optic nerve can lead to vision loss.

Iris

The iris is the colored part of the eye. It is a muscular diaphragm that controls the amount of light that enters the eye. The iris contracts in bright light to reduce the amount of light that enters the eye, and it dilates in low light to allow more light to enter the eye.

Treatments

There are a variety of treatments available for common eye conditions, such as cataracts, glaucoma, and macular degeneration. Treatment options will vary depending on the severity of the condition and the individual’s needs.

Common eye treatments include:

• Cataract surgery: Cataract surgery is a procedure to remove the clouded lens of the eye and replace it with a clear artificial lens.
• Glaucoma surgery: Glaucoma surgery is a procedure to create a new drainage channel in the eye to lower eye pressure.
• Macular degeneration injections: Macular degeneration injections are injections of medication into the eye to slow the progression of the disease and preserve vision.

If you are experiencing any vision problems, it is important to see an eye doctor for a diagnosis and treatment plan.
