OBJECTIVE: To identify the epidemiological profile and prognostic factors of open globe injuries that require emergency surgical treatment.
DESIGN: Retrospective cohort study. SUBJECTS: Patients with OGI who underwent publicly funded emergency surgical treatment in the Federal District from 2014 to 2018.
METHODS: Data were collected by reviewing electronic medical records through a questionnaire and tabulated. The statistical analysis was performed in SPSS Statistics 26.0.0.0 (p ≤ 0.05).
RESULTS: A total of 359 records were included, corresponding to 336 eyes of 334 patients (294 males and 40 females). The average age was 32.7 years. The affected eye was the right eye in 165 cases, the left eye in 166 cases, and both eyes in 3 cases. The average time between injury and hospitalization was 75.7 h, and the time between injury and surgery averaged 173.7 h. The injury types were as follows: 197 penetrating; 109 rupture; 19 IOFB; 11 perforating. The injuries were in the following zones: 181 zone I; 82 zone II; 70 zone III. The OTS grades were as follows: 57 were classified as grade 1; 101 were grade 2; 142 were grade 3; 28 were grade 4; and 8 were 5. The most commonly performed surgeries were corneal suture, corneoscleral suture, and evisceration. The most common clinical features were traumatic cataract, herniated iris and hyphema. The following were risk factors for poor prognosis: zone III, time between trauma and surgery > 72 h, rupture injury, retinal detachment, disorganization of the eyeball, endophthalmitis, uveal prolapse, OTS classification 1 or 2, and low initial visual acuity. The following factors predicted a good prognosis: initial VA > 1/200, penetrating injury, OTS 4 and zone II.
CONCLUSIONS: The high frequency of many of these factors may explain the high rate of severe visual loss found. Injury localization in zone II was identified as a previously unrecognized protective factor against severe visual loss.
