ABSTRACT
ABSTRACT A 22-year-old man complained of low visual acuity and pain in his left eye for five days. His ophthalmological examination revealed 2+ anterior chamber reaction and a white, poorly defined retinal lesion at the proximal portion of the inferotemporal vascular arcade. There were retinal hemorrhages in the inferotemporal region extending to the retinal periphery. In addition, venous dilation, increased tortuosity, and ischemic retinal whitening along the inferotemporal vascular arcade were also observed. A proper systemic work-up was performed, and the patient was diagnosed with ocular toxoplasmosis. He was treated with an anti-toxoplasma medication, and his condition slowly improved. Inferior macular inner and middle retinal atrophy could be observed on optical coherence tomography as a sequela of ischemic injury. To our knowledge, this is the first report of combined retinal branch vein and artery occlusion in toxoplasmosis resulting in a striking and unusual macular appearance.
RESUMO
RESUMO Um paciente do sexo masculino, com 22 anos de idade, queixou-se de redução da acuidade visual no olho esquerdo por 5 dias. O exame oftalmológico mostrou reação de câmara anterior 2+ e uma lesão retiniana esbranquiçada, pouco definida, na porção proximal da arcada vascular temporal inferior. Foram observadas hemorragias retinianas na região temporal inferior estendendo-se à periferia, assim como ingurgitamento venoso, aumento da tortuosidade e palidez isquêmica da retina no mesmo quadrante. Exames laboratoriais corroboraram o diagnóstico de toxoplasmose ocular. O paciente melhorou lentamente após tratamento apropriado. Foi evidenciada atrofia da retina macular inferior interna e média à tomografia de coerência óptica, como sequela da isquemia retiniana. Para nosso conhecimento, este é o primeiro relato de oclusão retiniana combinada de ramo arterial e venoso em toxoplasmose ocular, levando a um aspecto fundoscópico atípico e peculiar.
