To present a novel noncontact meibography system with anterior segment optical coherence tomography (OCT), which is widely used in clinics for the anterior segment (cornea, anterior chamber angle, etc.), and compare the results with preexisting infrared meibography.
This research was carried out at the Seoul St Mary's Hospital with 2 volunteers. Preexisting infrared meibography was performed on the subjects, and photographs of the meibomian gland were taken again with the anterior segment OCT. With the anterior segment OCT, a tomogram of the meibomian gland could be taken and a picture of the whole meibomian gland could be taken from the infrared images for monitoring.
The resolution of the preexisting infrared meibography was a pixel size of 640 × 480. In the anterior segment OCT, the meibomian glands were clearly identified just beneath the palpebral conjunctiva. There was no problem in grading the meibomian gland with the infrared images for monitoring. The resolution was 239 × 178 or 129 × 95 pixels, depending on the save option of the photograph.
This novel meibography using anterior OCT yielded meibomian gland tomograms without any additional equipment, and overall infrared meibography was possible for grading. We believe this new technique will be useful in clinics for meibomian gland dysfunction and the like.
介绍一种新型的非接触式睑板腺照相系统，该系统结合了前节光学相干断层扫描（OCT），在临床上广泛应用于前节（角膜、前房角等），并将结果与现有的红外睑板腺照相术进行比较。
这项研究在首尔圣玛丽医院进行，有 2 名志愿者参与。对受试者进行现有的红外睑板腺照相术，并用前节 OCT 对睑板腺进行拍照。通过前节 OCT，可以拍摄睑板腺的断层图像，并从红外图像中拍摄整个睑板腺的图像进行监测。
现有的红外睑板腺照相术的分辨率为 640×480 像素。在前节 OCT 中，睑板腺在眼脸结膜下清晰可见。用红外图像进行监测对睑板腺进行分级没有问题。分辨率取决于照片的保存选项，为 239×178 或 129×95 像素。
这种新型的前节 OCT 睑板腺照相术无需额外设备即可获得睑板腺断层图像，并且可以进行整体的红外睑板腺分级。我们相信，这项新技术将在睑板腺功能障碍等临床应用中发挥重要作用。
