Central and Peripheral Corneal Thickness

Analysis of age, refractive error and gender related changes of the cornea and the anterior segment of the eye with Scheimpflug imaging

“…Dubbelman et al observed that the asphericity of both the anterior and the posterior corneal surface changes significantly with age, which results in a slight peripheral thinning of the cornea [11]. A significant thinning of the corneal periphery and a decrease in the ratio of peripheral to central thickness in the elderly was also reported in previous studies [15,16]. Other ex-vivo studies have shown that the cornea stiffens with age as a result of ultra-structural changes in the collagen fibrils of the corneal stroma that may lead to corneal surface changes [17,18].…”

Factors Influencing Central Corneal Thickness in a Turkish Population

“…16,18 In our study, gender did not seem to affect CCT as it did in several other studies. 1,15,16,32,33 Brandt et al found greater CCT values for women than for men. 18 In the study of Alsbirk et al, CCT readings of Caucasian men and Eskimo women were found to be greater than those of their gender counterparts.…”

The relationship between central corneal thickness and degree of myopia among Saudi adults

“…However, the results of these reports are conflicting. Some found that myopic subjects have a thicker [16], others a thinner CCT [17][18][19][20], while yet others found no correlation between CCT and myopia [21][22][23][24][25][26][27][28][29][30][31] (Table 2). This study showed no statistically significant difference between the mean CCT of the myopic and that of the emmetropic subjects.…”
