Abstract

In this comparative study, ASOCT of older treated(72-300 mon) primary congenital glaucoma(PCG) patients were compared with iOCT of younger untreated(1-23 mon) PCG. Differences between two groups with respect to posterior corneal morphology were studied. Observed morphological patterns within posterior cornea in older treated children (87 eyes) included: DM excrescences(70%), thickened DM (35%), intracameral twin protuberances(92%) and DM detachment(26%). Changes within PDL(28%) included thickening, breaks and detachments. Extent of Haab’s striae was associated with thickness of DM/PDL complex(p: 0.008) when analysed in treated group. In contrast, in untreated group(53 eyes), posterior corneal changes were limited to diffuse hyper-reflectivity of DM/PDL complex, with an inability to appreciate distinct DM tears. Haab’s striae become more circumscribed in eyes of older treated children compared to untreated PCG eyes, probably reflecting a healing response of posterior cornea over time.
