RESUMO
Acute lymphoblastic leukemia is a malignant hematopoietic neoplasia, which is rare in adults. Although ocular fundus alterations may be commonly observed in the course of the disease, such alterations are rarely the presenting signs of the disease. Here we describe the case of a patient with painless and progressive loss of visual acuity (right eye, 2/10; left eye, 3/10) developing over two weeks, accompanied by fever and cervical lymphadenopathy. Fundus examination showed bilateral macular serous detachment, which was confirmed by optical coherence tomography. Fluorescein angiography revealed hyperfluorescent pinpoints in the posterior poles. The limits of the macular detachment were revealed in the late phase of the angiogram. The results of blood count analysis triggered a thorough, systematic patient examination. The diagnosis of acute lymphoblastic leukemia B (CD10+) was established, and intensive systemic chemotherapy was immediately initiated. One year after the diagnosis, the patient remains in complete remission without any ophthalmologic alterations.

RESUMO A leucemia linfoblástica aguda é uma neoplasia maligna das células hematopoiéticas, incomum em adultos. Apesar da maioria dos casos apresentar alterações no fundo ocular no decurso da doença, estas são raramente forma de apresentação da mesma. Descreve-se o caso de uma doente com diminuição progressiva e indolor da acuidade visual (OD 2/10 e OE 3/10), que apresentava concomitantemente febre e adenopatias cervicais, com duas semanas de evolução. À oftalmoscopia apresentava descolamento seroso macular bilateral, confirmado por tomografia de coerência ótica. A angiografia fluoresceínica revelou pequenas lesões hiperfluorescentes tipo pinpoints no polo posterior. Nos tempos médios e tardios do exame adivinham-se os limites da bolsa do descolamento do neuroepitélio. As alterações encontradas no hemograma suscitaram um estudo sistêmico extenso. O diagnóstico de leucemia linfoblástica aguda B (CD10+) foi efetuado, iniciando-se, de imediato, quimioterapia sistêmica intensiva. Um ano após o diagnóstico a doente continua em remissão e sem alterações oftalmológicas de novo.
