Abstract
To evaluate characteristics and prognostic factors for functional success in eyes that present with no light perception (NLP) after open globe trauma.
The medical records of all subjects presenting to a single university referral center with visual acuity (VA) of NLP after sustaining an open globe eye injury from January 1, 2001, through June 30, 2010, were retrospectively analyzed to determine epidemiologic and clinical factors associated with visual outcomes.
Of the 73 NLP eyes (73 patients) that underwent primary repair and were included in the study, final VA was 20/100 in 1 eye (1%), counting fingers in 2 eyes (3%), hand motion in 9 eyes (12%), light perception in 5 eyes (7%), and NLP in 56 eyes (77%). Recovery of some vision on postoperative Day 1, pars plana vitrectomy operation, and Zone 2 injury were significantly associated with an improvement in final VA. Zone 3 injuries were the most likely to result in NLP final VA, although this difference was not statistically significant.
Visual recovery to light perception or better on postoperative Day 1 increases the likelihood of having a long-term improvement in VA. Pars plana vitrectomy may be beneficial in such eyes if posterior segment abnormalities are noted.
