Foveal Avascular Zone Area Analysis in Macular Hole Before and After Surgery Using Optical Coherence Tomography Angiography

BACKGROUND AND OBJECTIVE: To analyze the foveal avascular zone (FAZ) area in superficial and deep retinal layers in patients with macular hole (MH) before and after surgery. PATIENTS AND METHODS: The authors studied 14 patients with unilateral MH. They examined a 3 mm × 3 mm area at the fovea before and 6 months after surgery using spectral-domain optical coherence tomography angiography. RESULTS: In eyes affected by MH, the mean preoperative...
