Ophthalmic Evaluation and Management of Traumatic Accidents Associated with Retinal Breaks and Detachment: A Retrospective Study

Clinical characteristics and surgical outcome of pediatric and early adulthood retinal detachment

OBJECTIVE

The aim of this study was to evaluate and compare the underlying pathologies, demographic and retinal detachment characteristics in pediatric and early adulthood retinal detachment.

METHODS

Patients with rhegmatogenous, serous, or tractional retinal detachment aged 0-26 years were retrospectively reviewed. The preschool group (n = 4) comprised children aged 0-6 years, the pediatric group (n = 19) comprised children aged 7-16 years, and the early adulthood group (n = 13) aged 17-26 years. Demographic information and retinal detachment characteristics, type of surgery, and intraocular tamponade were analyzed. Postoperatively, the functional outcome, anatomic success, and ocular adverse events were evaluated. Due to the low patient number in the preschool group, statistical analysis was performed for pediatric group and early adulthood group only.

RESULTS

All causes of retinal detachment were present in the pediatric group, but only rhegmatogenous retinal detachment in the early adulthood group. In both groups, the main type of surgical intervention was pars plana vitrectomy (pediatric group: 52%, early adulthood group: 38%; p = 0.36). The type of intraocular tamponade varied statistically significantly between the groups (p = 0.014). Silicone oil was the main intraocular tamponade in the pediatric group (48%), whereas no tamponade (54%) followed by gas tamponade (46%) in the early adulthood group. Final attachment rate was similar in both groups (pediatric group: 89%, early adulthood group: 100%; p = 0.35). Re-detachment occurred significantly sooner in the pediatric group (1.3 ± 0.3 months) than in the early adulthood group (4.3 ± 1.4 months; p = 0.03).

CONCLUSION

In pediatric and early adulthood retinal detachment, pars plana vitrectomy appeared as a successful surgical intervention. Re-attachment rate and re-treatment were similar in both groups with a better functional outcome observed in cases of retinal detachment in early adulthood and poorer results in young children.

Altered spontaneous brain activity patterns in patients with unilateral acute open globe injury using amplitude of low-frequency fluctuation: a functional magnetic resonance imaging study

OBJECTIVE

The aim of this study was to evaluate altered spontaneous brain activities in patients with unilateral acute open globe injury (OGI) using amplitude of low-frequency fluctuation (ALFF) method and its relationship with their clinical manifestations.

PATIENTS AND METHODS

A total of 18 patients with acute OGI (16 males and two females) and 18 healthy controls (HCs, 16 males and two females) closely matched in age, sex, and education were recruited in this study. The ALFF method was used to evaluate the altered spontaneous brain activities. The relationships between the mean ALFF signal values of different brain regions and the clinical features were evaluated by correlation analysis. Acute OGI patients were distinguished from HCs by receiver operating characteristic curve.

RESULTS

Compared with HCs, acute OGI patients had significantly higher ALFF values in the left cuneus, left middle cingulum cortex, and bilateral precuneus. Furthermore, the age of OGI patients showed a negative correlation with the ALFF signal value of the left middle cingulum cortex (r=-0.557, P=0.016) and a negative correlation with the mean ALFF signal value of the bilateral precuneus (r=-0.746, P<0.001). The ALFF signal value of the bilateral precuneus was negatively correlated with the duration of OGI (r=-0.493, P=0.038) and positively correlated with the vision acuity of the injured eye (r=0.583, P=0.011).

CONCLUSION

Acute OGI mainly induces dysfunction in the left cuneus, left middle cingulum cortex, and bilateral precuneus, which may reflect the underlying pathologic mechanisms of abnormal brain activities in OGI patients.
