Background: Traumatic cataract is the leading cause of significant monocular visual impairment in children. The cause of this type of cataract is preventable penetrating or blunt ocular injury. Lens extraction can improve the visual acuity but it also depends on the extent of the injury to other ocular structures. Objective: To describe the features of pediatric traumatic cataract presenting at a tertiary eye center in Indonesia. Methods: This study is a descriptive study and the data were collected retrospectively from the medical records of the patients who were diagnosed as pediatric traumatic cataract over the period of January 1st 2019 to December 31st 2019. Demographic data, trauma characteristics, clinical features, management, and pre- and post-operative Best Corrected Visual Acuity (BCVA) were reviewed retrospectively. Results: A total of 37 patients were diagnosed as pediatric traumatic cataract. Among these patients, 78.38% were boys, with the mean age of 9.14

This study explored the thermo-chemical properties of industrial hemp hurd with different provenances,maturity stages,and retting *** findings were then compared to hemp hurd used in the fabrication of citric acid-bonded ultra-low-density hemp hurd ***-gas chromatography-mass spectrometry(Py-GC/MS),Fourier-transform infrared spectroscopy(FTIR),and thermogravimetric analysis(TGA)were employed to document the variability of the hurd and comprehend the potential impact on biobased composite *** choice of cultivar,maturity stage,and processing modality significantly influenced the chemical composition,presence of functional groups,and thermal stability of the ***-GC/MS revealed substantial variations in the lignin-to-carbohydrate(L/C)ratio,along with the absence of fatty acids in certain *** FTIR signals confirmed consistent functional groups,differences in peak intensities were indicative of carbohydrate variations associated with maturity and retting duration,impacting the availability of hydroxyl groups for,i.e.,interparticle bonding in citric acid-based ***,it was observed that shorter retting durations initially enhanced the thermal resistance,but prolonged retting led to accelerated degradation,significantly reducing the hurd’s residual *** findings indicated notable differences among the samples,emphasizing the importance of investigating variables such as provenance/cultivar,maturity,and processing *** assessment is essential to ensure effective agronomic practices that align the raw material characteristics with the specific requirements of intended applications,such as the fabrication of biobased hemp hurd composites.
