Comparative Evaluation of the Prognostic Value Between the Ocular Trauma Score and the Pediatric Penetrating Ocular Trauma Score

Pattern of eye trauma among pediatric ophthalmic patients in upper and lower Egypt: A prospective two-center medicolegal study

Background

Ocular trauma is the leading cause of monocular blindness in children. This study aimed to identify and compare pediatric ocular injuries at two national university hospitals: Benha University Hospital (BUH) and South Valley University Hospital (SVUH) while evaluating the predictive utility of the Ocular Trauma Score (OTS) for post-traumatic permanent visual infirmity.

Design and methods

This multicenter observational study enrolled children under 18 years at BUH and SVUH Ophthalmology Departments from May 31 to December 31, 2022. Comprehensive medical histories and detailed data on eye trauma were obtained, with each undergoing thorough eye examinations at the initial presentation and during the 6-month follow-up period. The final visual outcome was permanent visual infirmity that was defined as the Best Corrected Visual Acuity in the better eye worse than 3/60 or near vision worse than N6 according to the International Classification of Diseases 11.

Results

The study included 120 cases evenly distributed between the two hospitals, with a mean age of 10.03 (±3.30) years, 74.17% male and 51.67% urban residents. Blunt, sharp, and foreign objects were the most common causes (39.17%, 33.33%, and 11.67%, respectively). Closed-globe injuries prevailed at BUH (83.33%) than SVUH (40.0%). Most injuries were accidental and outdoors, with an average interval of 9.93 (±23.57) hours to seek medical care. Lack of education, open-globe injuries, poor initial visual acuity, longer intervals from admission to intervention, and lower OTS were associated with visual impairment.

New model for the prediction of visual outcomes in young children with mechanical ocular conditions and comparison with other models

Purpose

Herein, we compared the efficacy among the Ocular Trauma Score (OTS), Toddlers Ocular Trauma Score (TOTS), and Pediatric Ocular Trauma Score (POTS) for prognosis prediction in Indian children who had mechanical ocular conditions causing traumatic cataract.

Methods

This prospective, interventional study recruited consecutive children undergoing operation for traumatic cataracts caused by mechanical eye injuries at Drashti Netralaya. The following details were obtained from their medical files: the circumstance and time of injuries, penetrating injury type, initial and final visual acuity (VA), time of operation, and associated eye diseases. Specific variables were employed to determine the OTS, TOTS, and POTS. For all patients, the final and predicted VA determined using all scores were compared using Fischer's exact test. Accuracy, specificity, and sensitivity were evaluated for all the scores by using the area under receiver operating characteristic curve.

Results

We enrolled 124 eyes. Patients' mean value for age was 4.6 ± 1.29 years; 44 (35.41%) and 74 (64.5%) were female and male patients, respectively. Visual outcomes significantly improved after operation, and the outcomes did not differ between closed- and open-globe injuries (P = 0.162). The actual and predicted VA did not exhibit a statistically significant difference among the three scores. TOTS and POTS were more suitable for evaluating low-risk injuries, whereas the OTS could more efficiently examine high-risk cases.

Conclusion

TOTS and POTS were more accurate than the OTS in VA prediction after operation in toddlers with traumatic cataracts caused by mechanical globe injury. TOTS and POTS were more suitable for evaluating low-risk injuries, whereas the OTS could more efficiently examine high-risk cases. All the examined scores can be helpful in estimating VA following treatment.

Predictive values of the Pediatric Penetrating Ocular Trauma Score and the Toddler/Infant Ocular Trauma Score in Brazilian children with open globe injury

Objective This study compared the prognostic value of the Pediatric Penetrating Ocular Trauma Score (POTS) with the Toddler/Infant Ocular Trauma Score (TOTS) in a cohort of Brazilian children with open-globe injuries.Methods This retrospective, observational case series included consecutive children with open-globe injuries seen at the Santa Casa de Sao Paulo Eye Emergency Service. The medical records of all patients were reviewed for data analysis, including the circumstance and time of injury, type of penetrating injury, initial and final visual acuity (VA), time of surgery, and associated eye diseases. The test characteristics of POTS and TOTS for VA were calculated and compared by the McNemar test.Results Thirty patients were included. The mean age was 3.9 ± 1.6 years; 20 were male patients and 10 were female patients. Most wounds were limited to the anterior segment (93.3%). The sensitivity for the POTS was higher than that of the TOTS (100%; 95% confidence interval [CI], 75.3–100 vs. 61.5%; 95% CI, 31.6–86.1; P = 0.014). The specificity was not significantly different (14.3%; 95% CI, 0.4–57.8 vs. 0%; 95% CI, 0–41.0; P = 0.563). The accuracy for the POTS was higher than the TOTS (70.0%; 95% CI, 45.7–88.1 vs. 40.0%; 95% CI, 19.1–63.9; P = 0.001).Conclusion In this cohort of Brazilian children with open-globe injuries, the POTS had better accuracy than did the TOTS in predicting VA after treatment.

Comparison of Two Scoring Systems in Pediatric Open Globe Injuries

PURPOSE

The aim of this study is to determine the demographic characteristics of pediatric open globe injuries, evaluate the ocular trauma scores (OTS), and predict the visual outcomes.

METHODS

All patients with pediatric open globe injuries who applied to Department of Ophthalmology, Faculty of Medicine, Mersin University between January 2018 and December 2019 were included in this study. Age, gender, type of injury, time of admission, time to surgery, OTS, and pediatric ocular trauma score (POTS) were calculated for each patient. The relation between these findings and final visual acuity (VA) after 12 months of follow-up was examined.

RESULTS

Forty-two eyes of 41 patients were included in this study. The most common injuries observed were sharp objects such as knives (23.8%) and stones (23.8%). The wound locations were zone I in 36 patients (85.7%) and zone II in 6 patients (14.3%). The most common concomitant eye pathologies were iris prolapse in 37 (88.1%) and hyphema in 29 (69.1%). The mean original OTS was 77.21 and the mean POTS was 46.78. Association between OTS/POTS and final VA was very good (Kendall Tau-b = 0.665, P < 0.001, Kendall Tau-b = 0.505, P < 0.001, respectively). The level of agreement between the predicted VA for OTS and that for POTS was almost perfect (kappa = 0.8726).

CONCLUSIONS

This study shows that the original OTS is still the gold standard in pediatric cases.

Predictors of visual outcomes in pediatric open globe injuries

PURPOSE

To identify predictors of visual outcomes in children with open globe injuries.

METHODS

The medical records of patients (≤18 years of age) with open globe injury from 2012 to 2020 at a single institution were retrospectively reviewed. The Pediatric Ocular Trauma Scores (POTS) and Toddler Ocular Trauma Scores (TOTS) were assessed against our cohort. Univariate and multivariate linear regression analysis was performed to identify predictors of visual outcome.

RESULTS

A total of 85 eyes of 85 pediatric patients (63 males [74%]) were included. Median patient age was 8.9 years. Final best-corrected visual acuity was significantly associated with presenting vision (P = 0.0001), age at injury (P = 0.02), lens involvement (P < 0.0001), retinal detachment (P < 0.0001), and location of injury (P < 0.0001). In a multivariate linear regression model, only presenting visual acuity and retinal detachment were independent predictors of outcome. When visual acuity was unknown, age at injury, lens involvement, and retinal detachment were independently associated with final visual acuity. POTS and TOTS scores moderately correlated with final best-corrected visual acuity (R² = 0.51 and R² = 0.53, resp.).

CONCLUSIONS

We identified patient characteristics predicting visual outcomes in a large US-based cohort of pediatric open globe injuries. POTS and TOTS scores moderately correlated with final visual acuity; however, the small study sizes from which they were derived preclude our identifying which predictors are most important. Development of a more predictive model will require a large multicenter study population or registry.

Comparison of the Ocular Trauma Score and Pediatric Ocular Trauma Score as Two Prognostic Models in Pediatric Open Globe Injuries

AIM

To compare the ocular trauma score (OTS) and the pediatric ocular trauma score (POTS) as prognostic models of visual outcome after open globe injury in children during a period of 19 years.

PATIENTS AND METHODS

A retrospective study of 36 open globe injuries in 36 patients younger than 18 years was conducted from January 2000 to January 2019. For each case, OTS and POTS points were calculated.

RESULTS

Significant differences were observed in our patients using the two models regarding categories 1 to 4. One third of the cases were in categories 1 and 2 using the OTS model, and nearly 60% using the POTS model. Nearly 60% of our patients were in categories 3 and 4 using the OTS model and 30.6% using the POTS model. In category 5, no difference was observed between the two models. The comparison of distribution of the percentage of final visual acuity between OTS and POTS model in each category revealed a significant difference in category 1 in final visual acuity 20/40 or more (25 vs. 50%) as well as in final visual acuity 20/20 (0 vs. 30%). In category 2, final visual acuity was not significantly different in 20/40 or more between the two models; however, there was a significant difference in final visual acuity 20/20 - 12.5% in the OTS model and 45.5% in the POTS model. In category 3, significant differences were revealed between the two models. Using the OTS model, final visual acuity 20/40 or more was observed in more than 60% and using POTS model in 100%; final visual acuity 20/20 was observed in 36.3% using OTS model and in 50% using POTS model. In category 4 and 5, no differences were observed between OTS and POTS models.

CONCLUSION

Our study did not confirm the benefit of POTS. The distribution of our cases among OTS categories demonstrated a significant difference between the two models with more cases distributed in lower categories in POTS group. In the POTS group, the prognosis for final visual acuity was significantly better in the first three categories than in the OTS group, probably as a result of a lower calculation for POTS points. In our opinion, the OTS model is easier to use, has a higher prognostic accuracy, and should be further used in counselling of paediatric cases.

Epidemiology of pediatric eye injuries requiring hospitalization in rural areas of Wenzhou and Changsha, China: a 10-year retrospective study

BACKGROUND

The aim of this study was to review the demographic and characteristic distribution data of serious rural pediatric eye injuries in Wenzhou and Changsha, located in Zhejiang Province in East China and Hunan Province in Central China.

METHODS

This retrospective study included hospitalized pediatric patients aged < 18 years with eye injuries at the Eye Hospital of Wenzhou Medical University and Xiangya Hospital of Central South University from January 2008 to December 2017. Demographic data, injury types, injury causes, and initial and final visual acuity (VA) were recorded and analyzed. The ocular trauma score (OTS) was calculated to assess the severity of injury and evaluate the prognosis. All patient data were obtained from the medical record systems.

RESULTS

In total, 1125 children were hospitalized during the 10-year period; 830 (73.8%) were males and 295 (26.2%) were females. The majority of the patients were aged 3 to 8 years (57.4%, n = 646). Among mechanical injuries (n = 1007), penetrating injury was the most common (68.4%, n = 689), followed by contusion (17.2%, n = 173) and rupture (8.1%, n = 82). Overall, the top three injury causes were sharp objects (n = 544, 48.4%), blunt objects (n = 209, 18.6%) and fireworks (n = 121, 10.8%). In Wenzhou, eye injuries occurred mostly in summer (n = 136, 29.1%), and sharp object-related eye injuries accounted for the highest proportion (n = 98, 72.1%). In Changsha, eye injuries occurred mostly in winter (n = 272, 41.3%), and firecracker- and fireworks-associated eye injury accounted for the highest proportion (n = 73, 26.8%). The final VA was positively correlated with the initial VA (r = 0.641, P < 0.001) and the OTS (r = 0.582, P < 0.001).

CONCLUSION

The age range of the susceptible pediatric population from rural areas was 3-8 years. Most eye injuries were penetrating, and the main cause of injury was a sharp object. Notably, the differences in the characteristics of eye injuries in the two areas were related to regional features.
