Correlation Intraocular Pressure With Intracranial Pressure

Correlation of Intraocular Pressure With Intracranial Pressure in Childs With Severe Trauma Brain Injury

Severe Trauma Brain Injury (TBIs) is a public health problem and monitoring of Intracranial Pressure (ICP) is a determinant key of it prognosis. Within the noninvasive methods to estimate the ICP, the measurement of intraocular pressure has been proposed because of its biological plausibility (proximity of the eye to the encephalic contend).

Objective. Correlate intraocular pressure with ICP in children with TBIs and obtain their utility values.

Objective. Correlate intraocular pressure with ICP in children with TBIs and obtain their utility values.

Material and methods. Correlation and diagnostic test design study. Inclusion criteria: children with TBIs admitted to the emergency room and indication of catheter for ICP measurement.

Exclusion criteria: injury or ophthalmic disease, glaucoma, encephalic death. Intraocular pressure was measured with electronic tonometer in both eyes prior to placement of the catheter for ICP measurement.

Correlation was estimated with Spearman's Rho. The utility values of the diagnostic test were obtained from an Receiver Operating Characteristic curve.

Inclusion Criteria:

1. Children with severe trauma brain injury (Coma Glasgow Scale smaller than 9 points),
2. who have been admitted to the pediatric emergency room
3. and in whom the treating neurosurgeon has decided to place a catheter for intracranial pressure measurement.

Exclusion Criteria:

1. Ocular trauma,
2. brain death,
3. know eye disease,
4. refusal of parents or guardians to participate in the study.
