To assess the potential of a new imaging technique, optical coherence tomography, for the diagnosis and monitoring of central serous chorioretinopathy. Optical coherence tomography is a novel noninvasive, noncontact imaging modality that produces high longitudinal resolution, cross-sectional tomographs of ocular tissue.
Optical coherence tomography is analogous to ultrasound, except that it uses light rather than sound to obtain higher image resolution in the retina. Cross-sectional tomographs of optical reflectivity within the retina are produced with longitudinal resolution of 10 microns. Optical coherence tomography was used to examine 16 patients at a referral eye center whose initial examination disclosed the clinical diagnosis of central serous chorioretinopathy. The optical coherence tomography results were correlated with slit-lamp biomicroscopy, fundus photography, and fluorescein angiography.
The cross-sectional view produced by optical coherence tomography was effective in objectively quantifying the amount of serous retinal detachment in the disease. Optical coherence tomography disclosed detachments that were undetected by slit-lamp biomicroscopy. Longitudinal measurements with optical coherence tomography were successfully able to track the resolution of subretinal fluid accumulation.
Optical coherence tomography is potentially useful as a new, noninvasive diagnostic technique for quantitative examination of patients with central serous chorioretinopathy and objectively monitoring the clinical course of the serous retinal detachment in this disease.
评估一种新的成像技术——光学相干断层扫描(Optical coherence tomography)用于诊断和监测中心性浆液性脉络膜视网膜病变的潜力。光学相干断层扫描是一种新型的非侵入性、非接触式成像方式,可生成眼部组织的高纵向分辨率横断面断层图像。
光学相干断层扫描类似于超声检查,不同之处在于它使用光而非声音来获取视网膜更高的图像分辨率。可生成视网膜内光学反射率的横断面断层图像,纵向分辨率为10微米。在一家转诊眼科中心,使用光学相干断层扫描对16例患者进行检查,这些患者的初始检查显示临床诊断为中心性浆液性脉络膜视网膜病变。将光学相干断层扫描的结果与裂隙灯生物显微镜检查、眼底照相和荧光素血管造影结果进行对比。
光学相干断层扫描产生的横断面视图能有效地客观量化该疾病中浆液性视网膜脱离的程度。光学相干断层扫描发现了裂隙灯生物显微镜检查未检测到的视网膜脱离。利用光学相干断层扫描进行的纵向测量成功地追踪了视网膜下液体积聚的消退情况。
光学相干断层扫描作为一种新的非侵入性诊断技术,对于中心性浆液性脉络膜视网膜病变患者的定量检查以及客观监测该疾病中浆液性视网膜脱离的临床病程可能具有重要价值。
