Nanophthalmos

Pachymetry, A- and B-scan ultrasonography, and ultrasound biomicroscopy (UBM) are useful in helping to establish a diagnosis.

All glaucoma types

Pachymetry readings are important in all types of glaucoma, including childhood glaucoma, to adjust for IOP readings.

In a small study, the mean central corneal thickness of children with different types of childhood glaucoma was measured. According to this study, in 34 children with glaucoma, IOP was overestimated by 3 mm Hg or more in 41.2% of them. In children with Sturge-Weber syndrome, the mean central corneal thickness was 591.9 +/- 23.1 µm, and, in children with aniridia, the mean central corneal thickness was 754.5 +/- 92.6 µm. [7]
