Figure 9. Regular and irregular regeneration of the fovea after vitrectomy with instillation of autologous platelet concentrate to stimulate the closure of a full-thickness macular hole.

A: Final foveal structure after hole closure in the eyes of patients 1, 4, 5, and 6 (from left to right). The foveas of patients 1 and 4 regenerated regularly while the foveas of patients 5 and 6 regenerated irregularly. Brackets: EZ defect. B: Putative mechanisms of macular hole formation and regular and irregular foveal regeneration after platelet-assisted closure of macular holes.
