Axial biometry of the entire eye using ultra-long scan depth optical coherence tomography.

摘要: Purpose To assess the repeatability of axial biometry entire eye using ultra-long scan depth optical coherence tomography (OCT) and to investigate agreement with IOLMaster measurements (Carl Zeiss Meditec). Design Prospective, observational case series. Methods There were 37 adult subjects enrolled in group 1 12 2. Using OCT, left eyes these groups measured 2 separate sessions. The images processed by a manual method custom-developed automatic software. A model was imaged for verification. OCT length measurement comparison. Results All parameters matched geometric parameters. In 1, there no significant differences all segmentation methods ( P > .05, paired t test). percentage coefficient segments ranged from 0.3% 3.9%. corresponding interclass correlation coefficients 0.946 0.999. between results appeared be strong R  = 0.999; 0.987; 0.988; Conclusions Automatic successfully each segment good repeatability. With further development segmentation, seems promising tool eye.
