The macula is a small cluster of nerve cells in the center of your retina that helps to focus images on the inside of the back of your eye. A macular hole occurs when there is a small break in the group of nerves. It can cause significant vision issues, such as reduced central vision or blurred vision. The size of the macular hole and where it is located on your retina will determine the extent of the change in your visual perception.
Left untreated, a macular hole can develop into more eye problems such as a retinal detachment. In mild cases of macular holes, eye drops or intraocular injections are used to reduce swelling and encouraging self closure of the hole. More often than not, vitrectomy surgery is the best and only treatment to repair a macular hole.
