Abstract

Abstract
Purpose: To investigate the relationship between anterior chamber angle (ACA) measurement, intraocular pressure (IOP) and refractive status of the eye in a young adult population with good ocular health.

Methods: Autorefractor (AR) captured data on corneal curvature and refractive errors in group participants and enabled comparison across refractive groups, gender, and age. Refractive errors were calculated in diopters as the spherical equivalent (SE). IOP was taken by Pulsar non-contact tonometer. All patients underwent the same optometric examinations of anterior eye data on corneal curvature, anterior chamber angle and corneal thickness captured with Topcon Maestro optical coherence tomography (OCT). Slit lamp was used for Van Herick method.

Results: Measurements were obtained from 118 eyes (right), of 26 males and 92 females aged 19–40 years with no ocular disease. There was no significant change Relationship between anterior chamber angle, IOP, corneal curvature and refractive status in young Caucasian adults in ocular profile across age range or by sex, apart from slightly steeper corneal profile for females (p=0.03). There was no significant correlation between IOP and ACA (p> 0.05), nor IOP and SE (p>0.05); however, when those with hyperopic SE were examined separately, there was a significant decrease in IOP with higher levels of hyperopic SE (p <0.05).

Conclusion: This study reports mean values for ACA were 39,39°, which gives a value of the open anterior chamber angle in young Caucasian adults. There was no significant relation between IOP, ACA or SE in the sample of young adults. However, higher level of hyperopic SE has a significant decrease in IOP and should be further investigated due to small sample of hyperopic subjects.
