Patient: 70 years of age, male, BCVA 0.5 at OD, 0.4 at OS, IOP 12/14 mmHg.
Ocular Medical History: visual impairment of unknown history.
General Medical History: prostata carcinoma with ossary metastasis in lateral orbital bones.
Main Complaint: transient obscurations of vision.
Purpose: to present optic nerve edema caused by ossary metastasis in orbital bone.
Methods: MRI, Colour Photography Posterior Pole, SD-OCT.
Findings:
MRI: orbital metastases of lateral orbital bone (arrow).
Colour Photography Posterior Pole: papilledema with retinal hemorrhages in OD and OS.
SD-OCT: papilledema with thickened optic nerve head (1.5mm/1.6 mm) in OD and OS.
Discussion:
Matlach et al. (1) reported, that orbital metastases occur in 2-5 % of cancer patients. Breast, lung and prostate cancer cause orbital metastases, and in up to 25 % of patients orbital metastasis is the initial sign of an unknown primary tumor. Clinical symptoms are papilledema, proptosis, ocular motility disorder and visual impairment.
