Effect of Age Under 20-60 years on Central Corneal Thickness

Abstract

The measurement of central corneal thickness is an important measure for the diagnosis of corneal pathologies. 510–520 microns is the standard central corneal thickness. Optical or ultrasound techniques are used for the measurement of thickness CCT. Objectives: To evaluate the effect of age on central corneal thickness in normal population visiting The University of Lahore Teaching Hospital, Raiwind road Lahore. Methods: Descriptive study design was used. Data was obtained from The University of Lahore Teaching Hospital, Raiwind road Lahore. The sample size of patients was 147 with ages ranging from 20 to 60 years. All genders were included in the data collection. Data were collected through convenient sampling technique by using researcher administrative performa and study was finalized in three months after the approval of synopsis. Data entry and analysis were done using computer software SPSS version 25.0. CCT was measured by non-contact Pachymeter (Canon TX-20P) and values were represented in the form of frequency tables and bar charts. Results: CCT drops over time, resulting in thinner corneas in older people. The dependence of CCT on age is greater in men. Mean CCT in male individuals were 538.66 µm and in females mean CCT was 540.37µm. In this study mean central corneal thickness values of right and left eyes were also compared. In males right mean CCT value was 537.94 µm and left mean CCT was 539.39µm. In females the mean CCT value of right was540.28µm and left mean CCT value was 540.47µm. Conclusions: The Central Corneal Thickness decreases with age. Men have thinner corneas than females in every age group.
