Prostatic carcinoma metastatic to choroid.

Metastatic prostatic carcinoma of the choroid became clinically undetectable after orchidectomy and oestrogen administration. The choroidal tumour rapidly regressed over a 2-month period and clinically disappeared, with restoration of 6/6 vision from 6/60 and return of visual field. This dramatic response and lack of complications make hormonal manipulation the preferred mode of initial therapy in prostatic carcinoma metastatic to the choroid.
