RESUMO
Abstract This paper provides a fast and inexpensive technique to prevent slippage of the infusion cannula from the EVA DORC® 27-gauge system. After the usual retrobulbar anesthesia, antisepsis and asepsis, a 2% hydroxypropyl methylcellulose drop is placed around the infusion cannula in the trocar to hold it in position. This technique prevents the slippage of the infusion cannula and both the surgical time and creation of the first sclerotomy in the eye can be shortened slightly.
Resumo Este artigo fornece uma técnica rápida e barata para evitar o deslizamento da cânula de infusão do sistema EVA DORC® 27-gauge. Após a habitual anestesia retrobulbar, antissepsia e assepsia, uma gota de 2% de hidroxipropilmetilcelulose é colocada ao redor da cânula de infusão no trocater para mantê-la em posição. Essa técnica evita o deslizamento da cânula de infusão e o tempo cirúrgico e da criação da primeira esclerotomia no olho podem ser ligeiramente reduzidos.

PURPOSE: To report a case of unilateral acute idiopathic maculopathy (UAIM) associated with yellow fever. OBSERVATIONS: A 59-year-old man presented with acute blurring of his vision 30 days after symptoms of yellow fever virus infection. Findings resembling unilateral acute idiopathic maculopathy of the left eye were noted on ophthalmoscopy, fluorescein angiography and optical coherence tomography. The right eye exam was normal. He was managed conservatively and recovered complete visual function in 8 weeks. CONCLUSIONS: We describe a case of unilateral acute idiopathic maculopathy disease in a patient infected by yellow fever virus confirmed with reverse transcriptase polymerase chain reaction (RT-PCR).
