Vascular features of full-thickness macular hole by OCT angiography

BACKGROUND AND OBJECTIVE: To compare the features of cystoid cavities associated with full-thickness macular hole (FTMH) imaged with optical coherence tomography angiography (OCTA) and en face OCT. PATIENTS AND METHODS: Prospective, observational, cross-sectional study. Clinical practice and observation. Thirteen patients (13 eyes) with FTMH were evaluated before vitrectomy. All eyes underwent OCTA or en face OCT imaging. RESULTS: There was a statistically significant positive correlation between groups for the total cavity area in both inner nuclear layer (P < .001; r2 = 0.82) and outer plexiform and Henle fiber layer complex (P < .001; r2 = 0.84). CONCLUSIONS: OCTA and en face image of cystoid cavities show very similar features and are complementary for the evaluation of the disease. The OCTA images show "vascular sliding" at the border of the cystoid cavities in FTMH, suggesting preservation of microvasculature surrounding the cystoid spaces during the disease process.
