Abstract
Anterior segment Optical Coherence Tomography (AS-OCT) evaluates the AS , providing anatomic details. With its high image resolution and scan speed a detailed and comprehensive analysis of the anterior chamber angle (ACA) is possible. It is Known that the pathogenesis of PCG is unclear, also that immature development of the anterior chamber is likely to be the main cause of elevated IOP.The development of hand-held spectral-domain OCT (HH AS- OCT) enabled portable, objective and non-contact imaging of patients unable to sit upright without the need for GA.This allows description of ACA structural changes in infants with PCG, and also excellent visualisation of the iris insertion.The purpose of this work is to investigate the potential of HH-AS OCT in assessing the AS of the eye in infants with PCG. Assessment was successfully attained for corneal parameters, iris thickness, angle width and angle structure identification in PCG patients. CCT was significantly higher in PCG patients. HCD showed a positive correlation with IOP, also there were no significant correlations between iris thickness or horizontal corneal diameter. Iris thickness was significantly higher in all regions in normal eyes except at the root temporally. Different degrees of loss of normal iris configuration with absence of iris crypts were detected in all eyes with congenital glaucoma.There was a highly significant increase in angle width in PCG group and there was no significant correlation between angle width with age & IOP in normal eyes. Also there was highly significant decrease in identified SC,SS and TM in PCG group; compared to the normal group
