What causes macular holes?

As we age, the vitreous, the gel-like substance that fills about 80% of the eye and helps it maintain a round shape, slowly shrinks and pulls away from the retinal surface. If the vitreous is firmly attached to the retina when it pulls away, it can tear the retina and create a macular hole. Macular holes can also occur as a result of high myopia, macular pucker, persistent cystoid macular edema and eye diseases such as diabetic retinopathy and Best’s disease.
