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 x 3 mm area at the fovea before and 6 months after surgery using spectral-domain optical coherence tomography angiography.
RESULTS: In eves affected by MH, the mean preoporative superficial FAZ (0.45 +/- 0.09 mm(2)) and deep FAZ (0.79 +/- 0.39 mm(2)) were significantly larger than the postoperative superficial FAZ (0.25 +/- 0.09 mm(2)) and deep FAZ (0.31 +/- 0.12 mm(2)), respectively (P < .001). The mean preoperative superficial ` of the affected eyes was the same as that of control eyes (0.41 +/- 0 +/- 10 mm(2)) (P = .23), but postoperative superficial FAZ was smaller than that of control eyes (P < ,0.1). The mean preoperative deep FAZ was larger (0.48 +/- +/-.11 mm(2)) (P = .019), but mean postoperative deep FAZ was smaller than that of control eyes (P < .001).
CONCLUSIONS: The authors revealed preoperative deep FAZ areas were more enlarged centrifugally than preoperative superficial FAZ in MH. Both postoperative superficial and deep FAZ shewod more centripetal contraction than those of the preoperative period.
