Acute and chronic optical coherence tomography findings in partial optic nerve head avulsion.

We present a case of partial optic nerve head (ONH) avulsion in a 15-year-old boy evaluated with optical coherence tomography (OCT) from 2 weeks to 15 months after acute injury. Distinct findings on OCT in the acute setting correlated with the diagnosis and with additional testing, including fundus photography, Humphrey visual fields, and clinical examination. OCT findings became less pronounced in the chronic setting. Our case highlights that OCT may be valuable in the acute setting for evaluating ONH avulsion in certain patients; however, OCT findings are less distinct in the chronic setting.
