Advantages:

To present the formation of macular hole and mechanism of its closure after vitrectomy.

Methods:

Both eyes of patients with macular holes were examined with spectral OCT (6 and 3um resolution).

Effectiveness / Safety:

Three different types of macular hole formation were discovered: cystoid spaces in inner retinal layers, vitreomacular traction syndrome and elevation of the photoreceptor layer. Macular hole closure and the recovery of foveal contour can take up to 12 months after surgery.

Take home message:

Spectral OCT due to better resolution and 3 dimensional images allows to visualize that macular hole often begins with elevation of the photoreceptor layer, which is probably due to traction. Postoperative healing begins in inner retinal layers and may be prolonged. Various postoperative defects have been observed.
