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.

Detailed description

After Pars plana vitrectomy combined with removal of the internal limiting membrane (ILM) and air filling, it can not only promote the closure of the macular hole in patients with idiopathic macular hole, but also improve the visual acuity of the affected eye. There are various studies to predict the visual acuity of patients after surgery recovery, but due to many factors that affect the effect of macular hole surgery, the improvement of visual acuity after retinal surgery varies greatly in different eyes. As a new type of ophthalmology device, OCTA plays an important role in measuring the size of the hole and the changes of retinal capillaries. Therefore, this study intends to calculate patient parameters based on OCT and OCTA equipment. Statistical software was used to analyze the relationship between each parameter and the best corrected visual acuity (BCVA) for at least one month after surgery.
