“…Similar OCT-morphologic changes have been observed at the border of colobomas, which was considered a different stage of the same disorder as PICC ( 51 ). The utilization of SS-OCT provides more detailed imaging that may elucidate the correlation between PICC and other complications as well as visual function.…”

Highly myopic optic nerve head (ONH) abnormalities encompass a series of complications resulting from the stretching of papillary and peripapillary structures during significant axial elongation. The morphological changes in the ONH typically initiate with disk tilting or rotation, progressing to PHOMS and PPA. Tissue defects in each layer manifest as focal lamina cribrosa defects (FLDs), peripapillary intrachoroidal cavitations (PICCs), and acquired pits of the optic nerve (APON). Anterior vitreous/vascular traction and posterior scleral protrusion may lead to prelaminar schisis as well as paravascular cysts and holes, which can potentially develop into retinoschisis. Traditional color fundus photography (CFP) is often insufficient for visualizing most of these lesions, yet their description and quantification benefit significantly from the advancements in optical coherence tomography (OCT) and OCT angiography (OCTA), complemented by fundus autofluorescence (FAF), indocyanine green angiography (ICGA), and three-dimensional imaging. The effective diagnosis and classification of ONH abnormalities heavily rely on a comprehensive understanding of their multimodal imaging features, as outlined in this review. These findings provide valuable insights into optic neuropathy in high myopia, establishing a solid foundation for future endeavors in disease monitoring and treatment guidance.

“…One hypothesis regarding the pathogenesis of peripapillary intrachoroidal cavitation involves the scleral extension around the ONH [ 5 ]. Comparable morphologic changes observed at the border of colobomas and peripapillary intrachoroidal cavitation on OCT are different stages of the same disorder [ 6 ]. Because of the presence of a cleft-like communication between the retina and the choroid with vitreous prolapse and anomalous vessels, some investigators believe that the anomaly is congenital in origin [ 7 ].…”

“…Sometimes, a myopic sinkhole is formed to facilitate the posterior flow of vitreous into the sclerochoroidal hollow, causing peripapillary choroidal thickening and cavitation [ 4 ]. Moreover, Cadherin or another cell adhesion molecule may possibly play an important role in the formation of peripapillary intrachoroidal cavitations [ 6 ].…”

BackgroundPeripapillary intrachoroidal cavitation was described as the presence of an asymptomatic, well-circumscribed, yellow-orange, peripapillary lesion at the inferior border of the myopic conus in eyes with high myopia.Case presentationA 66-year-old myopic Chinese man was enrolled and his multi-color imaging examination showed a well-circumscribed, caesious, peripapillary lesion coalesced with the optic nerve head vertically rotated and obliquely tilted, together with an inferotemporal sinkhole in the myopic conus. The optical coherence tomography images showed an intrachoroidal hyporeflective space, schisis, an intracavitary septum located below the retinal pigment epithelium and inserted beneath the optic nerve head, as well as a sinkhole between the peripapillary intrachoroidal cavitation and the vitreous space.ConclusionsBoth myopic colobomas and sinkhole in myopic conus may contribute the coalescence of intrachoroidal cavitation with optic nerve head. These qualitative and quantitative new findings will be beneficial for understanding its pathomorphological mechanism, and the impact on optic nerve tissue of myopic patients.

“…Em se tratando desta ligação é necessário ressaltar que a memória reforça os sentimentos do passado fortalecendo a criação de vínculos com os consumidores no presente, por meio da nostalgia (BOYM, 2001;HOLAK;MATVEEV, 2006). Ao exaltar elementos selecionados do passado, a elaboração da memória tem forte poder de despertar sentimentos nostálgicos, ou de saudades de momentos do passado que não podem mais se repetir.…”

A memória é um importante ativo estratégico e tem sido utilizada gradualmente e indiretamente nos clubes de futebol. Por estes papéis que desempenha e pelo potencial presente e futuro da utilização da memória nos clubes de futebol é que o objetivo deste estudo é o de identificar como a memória organizacional pode ser utilizada na construção da identidade dos clubes de futebol. Como referências teóricas foram apresentadas as conceituações de memória organizacional, identidade organizacional, invenção de tradição e nostalgia para entender como a memória pode ser utilizada pelos departamentos de marketing dos clubes de futebol. Apresentam-se, também, as considerações sobre o marketing pós-moderno e o retro marketing que são as teorias em marketing que, essencialmente, utilizam a memória. A metodologia adotada foi à qualitativa exploratória com pesquisa bibliográfica e entrevistas em profundidade com os consumidores dos quatro clubes de maior torcida do estado de São Paulo. Para analisar os dados foi utilizada a técnica de análise de conteúdo. Os resultados apresentados neste estudo mostram a articulação entre a memória organizacional e a identidade organizacional, auxiliando no direcionamento das ações de marketing que estejam amparadas em aspectos do passado para que atendam, adequadamente, os anseios de seus consumidores e que sirvam para identificar o que do passado e como o passado deve ser enaltecido.
