Chapter 11: Glaucoma in Children and Adolescents
Evaluating the Pediatric Glaucoma Patient
The role of pachymetry in the diagnosis and management of pediatric glaucoma is unclear. The average central corneal thickness (CCT) is 540–560 μm in children without glaucoma. CCT is lower than average in eyes with congenital glaucoma and in children with Down syndrome; CCT is higher than average in eyes that have had surgery for congenital cataract and in individuals with aniridia. It is also slightly higher in premature infants but decreases as the infant ages. The effect of CCT on the accuracy of IOP measurements in these groups is unclear, and nomograms cannot accurately be used to “correct” IOP measurements for differences in CCT measurements.
