[Visual outcomes and ocular survival in open-globe injuries]

ABSTRACT

To determine factors that affects and predicts final visual acuity, retinal attachment, and ocular survival after open-globe injuries. One-hundred sixteen eyes with open globe injuries were evaluated longitudinally from September 2001 to February 2004. Age, sex, involved eye, best corrected visual acuity [BCVA], afferent pupillary defect [APD], size and location of laceration, cataract, iris prolapse, vitreous prolapse, retinal detachment [RD], intraocular forgien body [IOFB], deep vitrectomy, and type of injury were evaluated as predisposing factors by logistic regression analysis for final visual acuity and retinal attachment and by Chi Square for survival rate. Enucleation was performed in 16 eyes [14%]. Low initial visual acuity, RD, and deep vitrectomy were detected as statistically significant risk factors for final visual acuity of 201200 or less. Positive APD and deep vitrectomy were statistically significant risk factors for final RD. BCVA of 20/300 or less, laceration size inore than 10 min, scleral and corneoscleral lacerations, vitreous prolapse, vitreous hemorrhage, RD, and sharp injury were risk factors for enucleation. Low BCVA, positive APD, and deep vitrectomy are risk factors for final low visual acuity. RD and deep vitrectoiny are risk factors for final RD. Low initial visual acuity; larger scleral lacerations, positive APD, and RD are negative factors for ocular survival
