PURPOSE: To investigate
the incidence and treatment of ocular firecracker trauma. To measure the
predictive value of ocular trauma score (OTS) in ocular firecracker trauma. METHODS: Consecutive
selection and retrospective analysis of ocular firecracker trauma. Certain
numerical values rendered to the OTS variables (visual acuity, rupture,
endophthalmitis, perforating or penetrating injury, retinal detachment and
afferent pupillary defect) at presentation were summated and converted into OTS
categories. The likelihood of the final visual acuities in each category was
calculated. The sensitivity and specificity of OTS were then calculated. RESULTS:54 eyes of 48 cases were
enrolled in the study. Male patients accounted for 85.4%. 62.5% patients were
younger than 15 years old. Bystanders accounted for 47.9%. Average following up
was 18.5±3.6 months. The most common clinical manifestation was ocular
penetration or perforation injuries. OTS summation mostly was 66-80 categories.
53.7% patients’ corrected visions at the last follow-up were 20/200 to 20/50.
OTS has 100% sensitivity and 100% specificity to predict NLP, LP/HM and 1/200
to 19/200. OTS has 45% sensitivity and 100% specificity to predict 20/200 to
20/50. OTS has 100% sensitivity and 65% specificity to predict ≥20/40. CONCLUSIONS: Clinical
manifestations of ocular firecracker trauma in our city are severe than that in
other countries and similar with the domestic reports. OTS has good predictive
value for ocular firecracker trauma, which has 100% sensitivity and 100%
specificity to predict NLP, LP/HM and 1/200 to 19/200. |
