Central and Peripheral Corneal Thickness in Full-Term Newborns by Ultrasonic Pachymetry

摘要: To establish a standard of normality, the authors studied central and peripheral (superior, inferior, nasal, temporal) corneal thickness 152 healthy, white race, full-term newborns (304 eyes) between 1 6 days old, using ultrasonic pachymetry. The mean (CCT) was 585 ± 52 nm (ranging from 446-706 nm). (PCT), significantly thicker than CCT (P = 0.0001), was: superior (SCT) 696 55 /zm, inferior (ICT) 744 62 nm, nasal (NCT) 742 58 |im, temporal (TCT) 748 nm. SCT thinner ICT, NCT, TCT 0.0001).

As far as we know, there only five articles literature about 2 " Until now, no one has published data (PCT) life purpose to normality corneas PCT points: (SCT), (ICT), (NCT), (TCT). These values used reference early diagnosis control
