“…Together, the findings emphasize the importance of diagnosing homonymous hemianopsia after trauma. Only one relevant, relatively large, case series (8 patients) has been published to date ( 9 ). An additional comparative study of 8 cases described the use of OCT to measure macular RNFL thickness in patients with OTL ( 24 ).…”

“…Anatomical evaluation of the optic nerve head including ancillary tests such as color photography of the optic nerve head, ocular ultrasonography (US), and optical coherence tomography (OCT) scans of the peripapillary retinal nerve fiber layer (RNFL) may help clinicians recognizing specific and sometimes subtle RNFL defect patterns such as the bowtie sign. However, the use of US or OCT in the diagnosis of OTL in patients with hemianopia has hardly been investigated (6)(7)(8)(9)(10)(11). In suspected cases, magnetic resonance imaging (MRI) scans of the head directed at the optic tract are used to locate the lesion (5,12).…”

Optic tract lesions (OTL) are often difficult to diagnose. We suggest an algorithm to simplify the often-challenging diagnosis of OTL. Clinical and imaging data were retrospectively collected from the electronic files of 6 patients diagnosed with OTL at a tertiary medical center in 2016–2020. The series included 4 children and 2 adults with an OTL caused by a glioma (n = 5) or motor vehicle accident (n = 1). Magnetic resonance imaging (MRI) revealed a suprasellar glioma involving the chiasm and tract alone (n = 1) and the ipsilateral optic nerve (n = 2) and only optic tract (3). Perimetry showed incongruent homonymous hemianopia in 3 patients. In two patients, perimetry could only be performed in one eye, and demonstrated hemianopia. In one patient perimetry was unreliable. Fundus examination revealed bow-tie atrophy in all patients. On optical coherence tomography (OCT) of the peripapillary retinal nerve fiber layer (RNFL) horizontal thinning was observed in the contralateral eye (n = 6). By presenting the information in a predefined order—visual field damage, OCT RNFL thickness, and MRI—the diagnosis could be easily reached even in children, and when other structures like the chiasm were involved. Fundus photographs easily detect bow tie atrophy in children. Systematic presentation of the data in a predefined order can ease the diagnostic process of OTLs.

“…The redesign of cultural artifacts, mainly through the means of industrial design, to continue to expand the cultural connotation of the form of derivatives, and promote cultural development. The recent cultural redesign mainly takes the direct application of decorative patterns [1], which often neglect the cultural connotation [2]. Emma found that artifact not only is the carrier of form and function, but also is a symbol of human and artifact from the emotional angle to finish redesign of pottery [3]; Lu has explored how to combine storytelling method with cultural symbol knowledge in cultural creative product [4].…”

Take the Liangzhu pottery as examples, an approach of form style recognition was proposed to further exploring the redesign of cultural artifacts from industrial design. Firstly, six major images of Liangzhu pottery was investigated by using KJ method and Factor Analysis; Then the relationship between the essential form factors and the major images were analyzed through Quantification Type I; Finally, the perceptual image knowledge base of Liangzhu cultural artifacts and a computer-aided form redesign system was built. Based on this system, the particular images conveyed by the cultural artifacts and the corresponding form features can be obtained, the traditional culture can be expanded. Thus the theory of form style recognition in the redesign of cultural artifacts is tested.
