Abstract
Purpose :
To describe the epidemiology and clinical outcome of open globe injuries (OGIs) in Japan over 10 years, and to examine preoperative factors influencing the visual prognosis after pars plana vitrectomy.
Methods :
The records of 373 patients with OGI (374 eyes), who had received surgery at nine hospitals, were retrospectively reviewed for this study. Patients’ demographic and clinical data were entered into a computerized database for review and statistical analyses. The following parameters were assessed; age, gender, initial and final visual acuity, duration between onset and surgery, presence of lens in the eye, characteristics of injury (i.e., type, zone, length, and cause), presence of ocular complications (i.e., iridodialysis, vitreous hemorrhage, retinal detachment, choroidal hemorrhage, proliferative vitreoretinopathy, and endophthalmitis), and the number of surgeries.
Main Outcome measures: The relationship between preoperative clinical parameters and final visual acuity.
Results :
The average age of the patients was 56.8 ± 22.1 years, and the majority of patients were male (73.5%). Compared to the overall cohort, work-related OGI was the most common and it was associated with significantly better final visual acuity than the rest of the patients, whereas patients with fall-related OGI showed significantly worse final visual acuity (P < 0.05). Considering the type of injury, the initial and final visual acuity were significantly worse in the rupture group than in the laceration group. Multiple regression analyses revealed that the final visual acuity was significantly associated with retinal detachment, initial visual acuity, type of injury, proliferative vitreoretinopathy, and patients’ age.
Conclusions :
The visual outcome in patients with OGI was related to retinal detachment, initial visual acuity, type of injury, proliferative vitreoretinopathy, and patients’ age. Ophthalmologists need to pay attention not only to the initial visual acuity but also to initial ocular conditions, such as the presence of ocular complications, to predict the visual outcome in patients with OGI.
