探讨Cirrus高清晰度光学相干断层扫描（HD-OCT）视网膜表面成像是否清晰地描绘了黄斑裂孔（MH）手术后分离的视神经纤维层（DONFL）外观的发展过程。我们回顾了接受MH手术并伴有内界膜剥离的患者的病历。然后使用三个主要标准选择病例：（1）由同一外科医生（S。K.），(2)术前和术后Cirrus HD-OCT成像，以及（3）最短3个月随访。所有病例均接受了完整的眼科检查。使用Cirrus HD-OCT提供的视网膜表面图像确定是否存在DONFL外观。如果可用，还使用彩色眼底照片进行确定。15例符合标准。11例（73%）患者在术后过程中通过视网膜表面成像确定了DONFL外观。在术后第一个月内，在任何OCT视网膜表面图像中均未检测到DONFL外观，在术后1至3个月之间逐渐变得明显，此后在所有病例中均保持可检测性，但在12个月时DONFL外观变得较难检测。当OCT视网膜表面图像上出现DONFL外观时，视网膜最内层的凹陷在横截面OCT图像上变得明显。有2例在彩色眼底照片上未观察到DONFL外观，但在OCT视网膜表面图像上检测到。Cirrus HD-OCT提供的视网膜表面成像似乎是评估MH手术后DONFL外观的一种有前途的选择。
To investigate whether retinal surface imaging by Cirrus high-definition optical coherence tomography (HD-OCT) clearly depicts the development process of a dissociated optic nerve fiber layer (DONFL) appearance after macular hole (MH) surgery. We reviewed the medical records of the patients who underwent MH surgery with internal limiting membrane peeling. The cases were then selected using three principal criteria: (1) surgeries performed by the same surgeon (S. K.), (2) pre- and postoperative Cirrus HD-OCT imaging, and (3) minimal follow-up of 3 months. All cases received a complete ophthalmologic examination. The presence/absence of a DONFL appearance was determined using a retinal surface image provided by Cirrus HD-OCT. Color fundus photographs were also used for determination if available. Fifteen cases met the criteria. A DONFL appearance was identified in 11 (73%) cases during the postoperative course by retinal surface imaging. A DONFL appearance was not detected in any OCT retinal surface image within the first postoperative month, gradually became distinct between 1 and 3 months after surgery, and remained detectable thereafter in all cases but one whose DONFL appearance became less detectable at 12 months. Indentations of the innermost retinal layer became apparent on cross-sectional OCT images as a DONFL appearance developed on OCT retinal surface images. There were two cases in which the DONFL appearance was not observed on color fundus photographs but detected on OCT retinal surface images. Retinal surface imaging provided by Cirrus HD-OCT appeared to be a promising option in evaluating a DONFL appearance after MH surgery.
