Macular

Macular refers to the macula, a small central area in the retina of the eye where vision is the sharpest. The macula is responsible for central, high-resolution, color vision that is needed for tasks such as reading, driving, and recognizing faces.

Anatomy

The macula is located in the center of the retina, the light-sensitive tissue at the back of the eye. It is approximately 5.5 mm in diameter and is responsible for the central 10 degrees of vision. The macula is divided into the umbo, foveola, foveal avascular zone, fovea, parafovea, and perifovea areas.

Function

The macula is responsible for central vision, which is used for tasks that require sharp vision, such as reading, driving, and recognizing faces. It also controls color perception.

Diseases and disorders

There are several diseases and disorders that can affect the macula, including macular degeneration, macular edema, macular hole, and macular pucker. These conditions can lead to vision loss and blindness.

Treatment

Treatment for macular diseases and disorders depends on the specific condition. Options may include medication, laser therapy, vitrectomy, and retinal detachment surgery.
