Objective: To describe one case of advanced prostate cancer first presenting with binocular diplopia due to retroorbital metastasis.
Methods: We present the case of a 54-year-old patient with the diagnosis of disseminated prostate cancer treated by complete androgen blockade.
Results: After the start of hormonal treatment, the patient initially improved although survival was limited.
Conclusions: Orbital metastasis is an infrequent site for prostate cancer dissemination which implies a limited survival oscillating between 7,5-30 months. In our case survival was 10 months from diagnosis.
