Macular Hole

A Macular Hole (pronounced: /ˈmakjʊlər hoʊl/) is a small break in the macula, the part of the eye responsible for detailed, central vision. The macula is the part of the retina that is located at the back of the eye.

Etymology

The term "Macular" is derived from the Latin word "macula" which means "spot" or "stain". The term "Hole" comes from the Old English word "hol" which means "hollow place" or "cavity".

Definition

A Macular Hole is a condition that affects the central part of the retina, known as the macula. This condition can cause blurred and distorted central vision. Macular holes are related to aging and usually occur in people over age 60.

Symptoms

Symptoms of a Macular Hole can include:

• Blurred vision
• Distorted vision
• A dark spot in the central vision

Causes

The exact cause of Macular Holes is not known, but they are often associated with:

• Aging
• Eye injury
• Retinal detachment
• Certain eye diseases such as diabetic retinopathy

Treatment

Treatment for a Macular Hole usually involves a surgical procedure known as a vitrectomy. In this procedure, the vitreous gel that is pulling on the macula is removed and replaced with a bubble containing a mixture of air and gas. The bubble acts as an internal, temporary bandage that holds the edge of the macular hole in place as it heals.
