光学相干断层扫描仪是一种新的非侵入性技术设备，可以获得视网膜的横断面、高分辨率图像-光学相干断层扫描仪(OCT)。该仪器可以准确评估各种黄斑和脉络膜视网膜病变，并及早发现青光眼损害。视网膜的图像类似于B超，纵向分辨率为10微米。由于OCT使用的是近红外波长(约840 nm)，因此检查对患者的不适程度最小。OCT检查适用于黄斑病变，如玻璃体-视网膜界面综合征，黄斑水肿的早期检测和定量评估，以及通过测量视网膜神经纤维层厚度来评估青光眼损害。该仪器的未来作用及其在临床诊断中的应用取决于软件的未来改进和更新。
The optical coherence tomograph is a new, noninvasive technical device that can obtain cross-sectional, high-resolution images-optical coherence tomographs (OCT)-of the retina. This instrument permits an accurate evaluation of various macular and chorioretinal pathologies and the early detection of glaucomatous damage. Images of the retina are obtained similar to ultrasound B-scan, with 10-microm longitudinal resolution. Because the OCT operates with a near-infrared wavelength (about 840 nm), the examination is of minimal discomfort for the patient. OCT examination is indicated in cases of macular pathologies such as vitreoretinal interface syndrome, in the early detection and quantitative assessment of macular edema, and in the evaluation of a glaucomatous damage by measuring the retinal nerve fiber layer thickness. The future role of this instrument and its applications for clinical diagnosis depend on the future improvement and updating of the software.
