OCT-A in Macular Surgery


ABSTRACT

Purpose:

To evaluate vessel density changes in the superficial and deep vessel plexus, and FAZ area before and after macular surgery.

Materials & Methods:

50 consecutive patients (25 with macular pucker and 25 with macular hole) were examined with OCT-A (RTVue-XR Avanti; Optovue, Fremont, CA, USA) before macular surgery and 1 week, 1 month, 3 months, and 12 months after surgery. Vessel density of the superficial and deep vessel plexus was measured in the foveal, parafoveal, and total macular area. The FAZ was manually traced and the area was measured in mm2. The fellow eye of each patient was used as a control eye.

Results:

In the macular hole group there was a significant increase of the foveal vessel density of the deep and superficial capillary plexus and a reduction of the area of the FAZ. In the macular pucker group there was a significant decrease of the foveal vessel density of the deep and superficial capillary plexus.

Conclusions:

OCT-A study of patients undergoing macular pucker and macular hole surgery demonstrated a change in foveal vessel density and FAZ area. This anatomic biomarkers could be correlated to functional changes such as visual acuity and microperimetry in further studies.
