Abstract Details

Purpose:

The aim of this study was to identify and describe anterior chamber angle features in infants (2 years or less) with PCG and to compare our findings to normal infants, using HH-AS-OCT as a diagnostic tool.

Setting:

Cairo University, Pediatric eye hospital.

Methods:

A descriptive cross-sectional study was conducted on 48 eyes of normal and glaucomatous infants < 24 months. Corneal pachymetry map, ACA width and iris thickness (IT) were measured. Trabecular meshwork (TM), Schlemm’s canal (SC), scleral spur (SS) identification were described.

Results:

Twenty-six PCG-eyes were studied and compared to 22 normal-eyes (overall mean age 9.12± 6.7months). Nasal and temporal ACA width in PCG infants was significantly larger than in normal infants (39.3±6.6° vs. 30.4 ±5.6, and 40.1±5.3° vs. 32.5 ±6.2 respectively) (p< 0.001). IT was significantly reduced (p<0.01). TM was identified in all normal eyes (100%) and 9 (34.6%) PCG-eyes. SC was identified in 16 (72.7%) normal eyes versus 4 (15.4%) PCG. Abnormal structure occluding the angle was seen in 7 (26.9%), and a hyper-reflective membrane in 5 (19.2%) PCG-eyes. Iris was anteriorly inserted in all PCG-eyes.

Conclusions:

Using HH-ASOCT permits thorough examination of the ACA in PCG infants, and helps in understanding the pathophysiology of the disease.
