Abstract

PURPOSE: To investigate the effect and correlation of mild traumatic brain injury (mTBI) on retinal thickness and visual function with multifocal pupillary objective perimetry (mfPOP). METHODS: Thirty seven male patients diagnosed with acute concussion occurring less than 30 days (21.6 ± 2.11 years, mean±SD), eleven athletes with a history of head trauma between 30 to 365 days (20.9 ± 2.0 years) and twelve athletes with no history of head trauma were recruited (22.50 ± 2.71 years) including eighteen healthy aged-matched controls (22.13 ± 1.89). RESULTS: On average, subjects who suffered acute mTBI also showed most delay in responses (7.2 ± 1.1 ms, P < 0.0005). Local correlations between retinal thickness and mfPOP delays showed significant negative correlations across all ETDRS regions in subjects with mTBI (P < 0.05). CONCLUSION: Retinal thickness change mTBI and the significant association with MfPOP response delays may be a biomarker of mild head trauma. Precis: Changes in retinal thickness and its association with functional change may identify subjects with mild traumatic brain injury. Background: Visual field loss in mild truamatic brain injury (mTBI) is often undiagnosed or underdiagnosed. Structural changes in the retina and its correlation with functional change may identify mTBI and assist in monitoring post injury.
