To examine the inner surface of the sclerotomy during microincision vitrectomy surgery by Miyake-Apple view.
The anterior half of porcine eyes was attached to a transparent acrylic plate with cyanoacrylate glue. Then, either a 23-gauge or a 25-gauge trocar-cannula was inserted through the sclera obliquely. The inner surface of the entrance site was observed posteriorly by Miyake-Apple view. These images were compared with the endoscopic view of two patients who underwent vitreous surgery for an epiretinal membrane.
When the trocar-cannula was inserted obliquely, the Miyake-Apple view showed that the ciliary epithelium at the sclerotomy site was stretched. When the trocar-cannula was inserted vertically, the ciliary epithelium was folded, and the folds remained even after the trocar was removed. Vitreous strands were seen incarcerated into the sclerotomy site. In human eyes, a folding of the ciliary epithelium was not clearly seen with the endoscopic view but the incarcerated vitreous was seen.
The Miyake-Apple view provided a precise, in vivo, observation of the inner surface of the entry site. It disclosed the morphological stress on the ciliary epithelium by the sclerotomy.
通过 Miyake-Apple 视图检查微创玻璃体切割手术中的巩膜切口内表面。
将猪眼的前半部分用氰基丙烯酸酯胶附着在透明亚克力板上。然后，通过巩膜以斜角插入 23 号或 25 号穿刺套管。通过 Miyake-Apple 视图观察入口部位的内表面。将这些图像与两名接受视网膜前膜玻璃体手术患者的内窥镜视图进行比较。
当穿刺套管以斜角插入时，Miyake-Apple 视图显示巩膜切开部位的睫状上皮被拉伸。当套管垂直插入时，睫状上皮折叠，即使套管被移除后，褶皱仍然存在。可以看到玻璃体条索被夹在巩膜切开部位。在人眼中，内窥镜视图并未清楚地显示出睫状上皮的折叠，但可以看到被夹入的玻璃体。
Miyake-Apple 视图提供了对进入部位内表面的精确、活体观察。它揭示了巩膜切开术对睫状上皮的形态学影响。
