The macular hole (MH) is a disorder of the visual center of the retina in humans. An untreated MH leads to loss of central visual acuity and reading ability. Surgery for early-stage macular holes has been very successful for many years and leads to very good anatomical and functional results. Despite continuous improvement of surgical procedures, the outcome for the later stages of MH is still unsatisfactory.

In a retrospective analysis, we investigated the effect of autologous platelet concentrates in patients presenting later stages of MHs (stage III-IV) with respect to anatomic success (hole closure) and recovery of vision. The application of platelets was performed during retinal surgery (pars plana vitrectomy, ppV). In addition, selected platelet concentrates were qualitatively analysed for growth factors and platelet adhesion.

In the first group, 74 % of the patients showed a good anatomical macular hole closure. The analyses of the platelet concentrates indicated a possible wound-healing effect due to growth factors (e.g. the platelet-derived growth factor, PDGF) and lesser to the ability of the platelets to adhere after ristocetin administration. Further optimization of the production process of platelet concentrates and of the surgical procedure in the second group of patients showed an increase of the anatomical success (92 %) and a very rapid increase of visual acuity within six weeks.

In the past, the primary goal of MH surgery was to optimize the surgical procedures. Only few concepts focused on wound healing. Based on our data, we postulate the use of autologous platelet concentrates in MH surgery as a healing concept, which helps to increase the functional success of late-stage macular hole surgery.
