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; r = 0.82) and outer plexiform and Henle fiber layer complex (P < .001; r = 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.

背景与目的
比较光学相干断层扫描血管造影（OCTA）和正面光学相干断层扫描（OCT）成像的全层黄斑裂孔（FTMH）相关囊样腔隙的特征。
患者与方法
前瞻性、观察性横断面研究。临床实践与观察。13例（13只眼）FTMH患者在玻璃体切除术前接受评估。所有患眼均接受OCTA或正面OCT成像。
结果
在内核层（P <.001；r = 0.82）以及外丛状层和Henle纤维层复合体（P <.001；r = 0.84）中，两组间囊样腔隙总面积均存在统计学显著正相关。
结论
囊样腔隙的OCTA和正面图像显示出非常相似的特征，且在疾病评估中具有互补性。OCTA图像显示FTMH囊样腔隙边界处存在“血管滑动”，提示在疾病过程中囊样间隙周围的微血管结构得以保留。[《眼科手术、激光与视网膜成像》。2017；48：62 - 68。]
