What is a macular hole?
Macular hole is a defect in the centre of the macula. The macula is a part of the retina (film at the back of the eye) which is responsible for central vision. Symptoms of macular hole include a dark or blind spot in the centre of the vision.
As we age, the vitreous pulls away from the retina. This is called a posterior vitreous detachment. In the majority of population, posterior vitreous detachment will occur with no problem, however, in certain people, it will pull stronger on the retina and form a macular hole.
Only macular holes occurring through all the layers of the retina (full thickness macular holes) will require treatment.
