Resumo: | Purpose: To describe the imaging features of choroidal nevi using optical coherence tomography angiography (OCT-A) and optical coherence tomography with enhanced depth imaging (EDI-OCT). Material and Methods: Retrospective observational case series of patients with choroidal nevi. The tumor and overlying retina structural features were analyzed with EDI-OCT. The OCT-A images were evaluated for vascular changes at the level of the retinal plexus, outer retina, choriocapillaris and choroid. Statistical analysis were performed using IBM SPSS Statistics. Results and Discussion: 21 patients, 73% female, were included. The mean age was 55±10 years old. The mean tumor thickness was 359±42 µm and the mean largest basal diameter was 3089±261µm. 27% of the nevi had their epicenter at the macula. US showed a solid flat lesion with high reflectivity. With EDI-OCT all lesions appeared as a highly reflective band within the choriocapillaris with posterior shadowing. 67% of the nevi had drusen and 25% had drusenoid pigment epithelium detachment (dPED). Chronic changes in the retina were found in 52% and subretinal fluid in 16%. On OCT-A the superficial and deep capillary plexus were normal. A neovascular membrane was detected in 1 case and a polypoidal vasculopathy in 3 cases. At the level of the choriocapillaris, 16% were hyperreflective, 74% were isorreflective and 10% were hyporreflective. Conclusion: Our work demonstrated that OCT-A may be useful in the diagnosis of vascular complications associated to small stable nevi. The identification of vascularized PEDs is crucial in order to decide treatment, avoiding further visual impairment. |

Materiais e Métodos: Estudo retrospetivo de série de casos de doentes com nevus da coroideia. A análise estrutural foi realizada com EDI-OCT. Nas imagens do OCT-A foram avaliadas alterações vasculares nos plexos retinianos, retina externa, coriocapilar e coroideia, ao nível do tumor e da retina suprajacente. A análise estatística foi realizada com o programa IBM SPSS Statistics. Resultados e Discussão: Foram incluídos 21 doentes, 73% do sexo feminino. A idade média foi de 55±10 anos. A espessura média do tumor foi de 359±42 µm e o maior diâmetro basal foi de 3089±261 µm. 27% dos nevus tinham o seu epicentro na mácula. O exame ecográfico mostrou uma lesão sólida plana de alta refletividade. No EDI-OCT as lesões apresentavam-se como um banda hiperrefletiva ao nível da coriocapilar condicionando sombra posterior. Drusens estavam presentes em 67% dos nevus e descolamento do epitélio pigmento (DEP) de caraterísticas drusenóides em 25%. Ao nível da retina 52% dos nevus apresentavam alterações crónicas e 16% tinham fluido subretiniano. No OCT-A os plexos superficial e profundo não apresentavam alterações. Foi detetada uma membrana neovascular em 1 caso e caraterísticas sugestivas de vasculopatia polipoidal em 3 casos. Ao nível da coriocapilar, 16% demonstravam hiperrefletividade, 74% isorrefletividade e 10% eram hiporrefletivos. Conclusão: O nosso trabalho demonstra a importância do OCT-A no diagnóstico de complicações vasculares associadas a nevus coroideus estáveis. A identificação de DEPs vascularizados é crucial para a decisão terapêutica, de forma a impedir maior disfunção visual.Ajnet2020-10-21T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.48560/rspo.19806eng1646-69501646-6950Henriques, Susana PintoBasto, RitaRoque, JoanaCoutinho, InêsColaço, LuísaPinto, FilomenaCosta e Silva, FilomenaPrieto, Isabelinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-09-22T17:06:11Zoai:ojs.revistas.rcaap.pt:article/19806Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:01:44.236454Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
