Zone, visual acuity affect outcomes after traumatic injury

BOSTON — Patients with low visual acuity at presentation for a traumatic eye injury tended to have worse vision at final follow-up and a higher risk for enucleation, according to a poster presented here at the American Society of Retina Specialists meeting.
Sami H. Uwaydat, MD, and colleagues presented the findings of a retrospective chart review of 87 eyes with globe injuries between 2009 and 2015. At presentation, 11.49% of these eyes had no light perception (NLP), and 10.34% of eyes were eventually enucleated.
Patients with poor visual acuity at presentation correlated with worse visual acuity at final follow-up (P < .0001), and 60% of enucleated eyes were NLP at presentation.
The injuries were classified by zones, and risk for NLP at final follow-up varied by zone. In the cohort, 11.49% of patients had a zone 0 injury (closed-globe injury), 22.99% had a zone 1 injury (cornea), 24.14% had a zone 2 injury (limbus to 5 mm and posterior to limbus), and 40.23% had a zone 3 injury (greater than 5 mm and posterior to limbus). Less than 10% of patients with a zone 0, 1 or 2 injury had NLP vision at final follow up, compared with 22.86% of patients with a zone 3 injury.
Researchers noted that use of oral prednisone did not affect final visual acuity. – by Robert Linnehan
