主 题：central corneal thickness intraocular pressure gender age refraction
摘 要：The central corneal thickness （CCT） in age 48 years or less of Chinese was characterized and its relationship with gender, age, refraction and intraocular pressure （IOP） was investigated. Right eyes of 1669 participants were included in this study （880 men, 52.7 % and 789 women, 47.3 %）. Mean age of the samples was 23.8±5.9 years. After the examination of corneal topography and refraction, Goldman applanation tonometry was carried out by one physician. Tonometric values were the mean of three consecutive readings. Subsequently, another physician carried out ultrasonic pachymetry with the DGH 2000 AP ultrasonic pachymeter. Six measurements were made at the center of the cornea of each eye. The mean value was used for analysis. The results showed that mean CCT of male participants was 551.33±34.62 μm, 5.79μm more than that of female participants. Linear regression analyses revealed that CCT was negatively related with age only in female and no association was found between refractive status and CCT. IOP was positively related to CCT, and there was a difference in IOP of 1.5 mmHg （1 mmHg=0. 133 kPa） per 100 μm difference in CCT. Ocular hypertension group was prone to have thicker cornea than average. The results indicated that in adult Chinese CCT tended to decrease with aging in female only. IOP measured by Goldmann tonometry was positively related with CCT so that CCT should be measured a- long with IOP.
