NCT04957459

Brief Summary

This study retrospectively analyzed the relationship between the preoperative optical coherence tomography(OCT) and optical coherence tomography angiography(OCTA) software related parameters of patients with idiopathic macular hole, the patient's own clinical data and the best corrected visual acuity (BCVA) for at least one month after surgery.
