The goal of this prospective interventional study is to to compare the micro vascular and structural changes between surgery with and without ILM flap to repair macular hole. The main questions it aims to answer are: * What are the macular micro vascular and structural changes pre and post repair of idiopathic full thickness macular hole and what is the correlation between these changes and visual recovery. * Is there are any prognostic values of the micro vascular status of the macula could be assessed preoperatively. * What are the differences regarding these micro vascular and structural changes between repair with and without ILM flap. Participants will be: * Subjected to pars plana vitrectomy to repair macular hole. * Examined by optical coherence tomography angiography pre and post operative Researchers will compare: Group A: eyes treated without ILM flap Group B : eyes treated by ILM flap to see if there are differences regarding the micro vascular and structural changes in the macular area.
