Resumo: Purpose: To report a case of a 48-year-old female with sudden decrease of visual acuity (VA) in the right eye (RE). Methods: This is a retrospective and descriptive case report based on data from clinical records, patient observation and analysis of diagnostic tests. Results: A 48 year old woman with no relevant personal or family history except for the use of oral contraceptives, presented loss of visual acuity, central and superior scotoma in the right eye. Best corrected visual acuity (BVCA) was 20/32 in the right eye (RE) and 20/20 in the left eye (LE). RE fundoscopy revealed cotton wool spots in the territory of the inferior temporal retinal artery. Optical coherence tomography (OCT) showed increased central macular thickness mainly at the level of the nerve fiber layer. RE fluorescein angiography showed stop of fluorescein at the emergence of the inferior temporal artery.  RE showed a superior altitudinal defect respecting the horizontal meridian. An intravitreal injection of 3.2mg triamcinolone was given within 24 hours. RE BVCA improved up to 20/20-1L at 3 months, with improvement of the visual field defect with time. Conclusion: Intravitreal steroids given within a few hours of the arterial occlusion may limit the spreadout of apoptosis nearby the ischemic areas, limiting visual field and central vision losses.

Métodos: Trata-se de um relato de caso clínico retrospetivo e descritivo, baseado em dados do processo clínico, observação da doente e análise de testes diagnósticos complementares. Resultados: Doente do sexo feminino de 48 anos sem história pessoal ou familiar relevante, com a exceção do uso de contracetivos orais, apresenta perda de acuidade visual súbita, escotoma central e superior no OD. A melhor acuidade visual corrigida (MAVC) era de 20/32 no olho OD e 20/20 no olho esquerdo (OE). A fundoscopia do OD revelava manchas algodonosas no território da artéria retiniana temporal inferior. A tomografia de coerência ótica (OCT) mostrava aumento da espessura macular central principalmente ao nível da camada de fibras nervosas. A angiografia com fluoresceína do OD mostrava paragem de circulação da fluoresceína no surgimento da artéria retiniana temporal inferior. Os campos visuais demonstravam um defeito altitudinal superior em relação ao meridiano horizontal. Uma injeção intravítrea de 3,2 mg de triamcinolona foi administrada num período inferior a 24 horas. A MAVC melhorou até 20 / 20-1L em 3 meses, com melhoria do defeito do campo visual. Conclusão: Os esteroides intravítreos administrados em poucas horas após a oclusão arterial podem limitar a extensão da apoptose nas proximidades das áreas isquémicas, limitando defeitos de campo visual e as perdas da visão central.    Ajnet2019-07-05T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/reporthttps://doi.org/10.48560/rspo.17005eng1646-69501646-6950Pereira, Joana MendesCampos, AntónioSantos, MónicaAragão, HenriqueAragão, HenriqueVieira, Maria JoãoSousa, João Paulo Castroinfo: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:RCAAP2022-09-22T17:06:08ZPortal AgregadorONG
