Macular hole - External and Internal Eye

Synopsis
Vitreous tractional forces on the anatomically thin perifoveal region can lead to separation of the retinal layers. This can happen immediately after trauma or, more commonly, over months, leading to full-thickness macular holes.
Approximately 3% to 9% of macular holes close spontaneously over a 6-year period. The presence of a posterior vitreous detachment (PVD) decreases the risk of progression from an early macular hole to a full-thickness defect. Development of a macular hole in the fellow eye is also decreased in patients with a PVD in that eye.
