The purpose of this study was to investigate the effect of image quality on retinal nerve fiber layer (RNFL) and retinal thickness measurements obtained using three commercially available spectral domain-optical coherence tomographers (SD-OCT). Subjectively determined good, medium and poor quality images were obtained from four healthy and one glaucoma suspect eyes. RNFL and retinal thickness measurements were compared as a function of image quality. Results indicate that when image quality is within the range specified as acceptable by SD-OCT manufacturers, RNFL and retinal thickness measurements are comparable.
本研究的目的是调查图像质量对使用三种市售光谱域光学相干断层扫描仪（SD-OCT）获得的视网膜神经纤维层（RNFL）和视网膜厚度测量结果的影响。从4只健康眼睛和1只疑似青光眼眼睛中获取了主观判定为质量良好、中等和较差的图像。将RNFL和视网膜厚度测量结果作为图像质量的函数进行比较。结果表明，当图像质量在SD-OCT制造商规定的可接受范围内时，RNFL和视网膜厚度测量结果具有可比性。
