Optic Nerve Head Morphology in Children With Perinatal Onset Static Encephalopathy
In Brief
An observational study for Cerebral Palsy. Completed, enrolled 61 participants across 1 site.
Detailed Summary
Hypothesis: Children born prematurely (between 8 and 9 months) with brain damage have an abnormal appearance of the optic nerve (nerve in eye) that resembles glaucoma (cupping) compared to those born before 8 months. Purpose: to see how often children who are born prematurely and have suffered brain damage, have abnormal appearance of the optic nerve (nerve in the eye) which mimics glaucoma (cupping). This optic nerve cupping is most often seen when children are born after 8 months and is rarely seen in children born before 8 months. Children born prematurely are known to have injuries to their brain as they are not yet fully developed. This often involves the part of the brain that involves vision. Clinicians have observed that these children have an abnormal appearance of the optic nerve (nerve in the eye), which has the appearance of glaucoma. These children often undergo extensive and often unnecessary invasive tests to rule out glaucoma. The investigators wish to establish the prevalence of this abnormality so that children are not subjected to unnecessary investigations. The investigators also want to understand how the optic nerve cupping (similar clinical picture as glaucoma) is related to the approximate timing and extent of the brain injury, the type of cerebral palsy and the motor disability of these children.
