Abstract:
BACKGROUND፡ The aim of this study was to determine whether Central Corneal Thickness (CCT) is associated with intraocular
pressure measurement (IOP) with a Non-contact tonometer and the
Goldmann applanation tonometer in glaucoma patients.
MATERIALS AND METHODS: The study involved two hundred
and thirty-two eyes of clinically diagnosed glaucoma patients
receiving care at a referral facility. IOP measurements were
obtained using both the Non-Contact Tonometer (NCT) and
Goldmann Applanation Tonometer (GAT). The association
between age, ethnicity, and CCT, as well as CCT on the measures
of NCT and GAT, were analyzed.
RESULTS: There were 64(55.2%) males and 52 (44.8%) females
and their ages ranged from 18 to 85 years (mean age = 47.72; SD ±
15.75 years). There was a weak positive correlation between the
CCT and NCT findings in the right eye (r = 0.19, n = 116, p < 0.05)
and in the left eye (r = 0.25, n = 116, p < 0.05). However, there was
no correlation between CCT and GAT measurements. Age had a
significant correlation with CCT while gender and ethnicity had no
significant correlation.
CONCLUSION: The study found a significant association between
CCT and NCT. However, there was no significant association
between CCT and GAT. CCT had an association with age but
independent of gender and ethnicity since there was no significant
relationship between these variables.
