Ciliary body damage, closed funnel retinal detachment and choroidal damage are independent risk factors for no light perception after open-globe injury. However, these three risk factors are not prognostic indicators for a visual outcome of no light perception.
Researchers used the Eye Injury Vitrectomy Study database to conduct a case-control study and investigate risk factors among 72 eyes with no light perception. They evaluated whether potential risk factors predict an unfavorable visual outcome.
All eyes underwent surgical intervention, and the researchers evaluated type and zone of injury with two controls per case who had vision of light perception or better.
Results showed that 67 eyes with no light perception had ciliary body damage, closed funnel retinal detachment or choroidal damage; some cases had more than one of these risk factors. Five cases that did not have these risk factors had a favorable visual outcome after vitreoretinal surgery. Additionally, 43 of the 67 eyes recovered light perception or better after vitreoretinal surgery, according to the study.
"Traumatized eyes with [no light perception] may recover light perception or better vision if appropriate interventional measures are used for treatment of the injured ciliary body, retina and choroid," the study authors said.
