The macula is part of the retina at the back of the eye. It is only about 5mm across, but is responsible for our central vision, most of our colour vision and the fine detail of what we see. The macula has a very high concentration of photoreceptor cells – the cells that detect light.

Can macula be repaired?

A macular hole can often be repaired using an operation called a vitrectomy. The operation is successful in closing the hole in around 9 out of 10 people who’ve had the hole for less than 6 months. If the hole has been present for a year or longer, the success rate will be lower.
