Clinical Trial Summary

Aim of the Study:To report the structural and visual outcomes of plasma rich in growth factors in closure of challenging macular holes


Description:

Challenging full thickness macular holes ( FTMH) include : Recurrent FTMH Persistent (refractory) FTMH Macular holes in eyes with pathological myopia Large macular holes with an inner diameter of more than 650 µm. Plasma rich in growth factors (PRGF) is characterized by a moderate concentration of platelets, in the absence of leukocytes. This absence of leukocytes is based on the fact that they synthesize matrix metalloproteinases, free radicals, and proinflammatory cytokines, which do not contribute and even impair the altered tissue regeneration Aim of the Study:To report the structural and visual outcomes of plasma rich in growth factors in closure of challenging macular holes

Intervention

Biological:
Plasma rich in growth factors ( PRGF )
Plasma rich in growth factors (PRGF) is characterized by a moderate concentration of platelets, in the absence of leukocytes. This absence of leukocytes is based on the fact that they synthesize matrix metalloproteinases, free radicals, and proinflammatory cytokines, which do not contribute and even impair the altered tissue regeneration
