A 39-year-old female with elevated serum cobalt levels from her bilateral hip prostheses presented with a 3-week history of blurred vision in her left eye. Optical coherence tomography revealed patchy degeneration of the photoreceptor-retinal pigment epithelium (RPE) complex. The lesions were hypofluorescent on indocyanine green angiography. We postulate that this is a case of implant-related chorio-retinal cobalt toxicity.

A 63-year-old woman with a 1-month history of blurred vision in the right eye was found to have a right optic nerve sheath meningioma. She was treated with fractionated proton beam therapy using a total dose of 50.4 cobalt gray equivalent (CGE) in 1.8 CGE fractions, with subsequent improvement in vision. Twenty-seven months later, the patient reported a 6-week history of progressive blurred vision in her right eye. Magnetic resonance imaging revealed enhancement of the right optic nerve consistent with radiation optic neuropathy (RON). We are unaware of any previous reports of RON when radiotherapy doses fall within the current recommended guidelines of <55 CGE fractionated into daily doses <2 CGE.

A 40-year-old woman with no known medical conditions or allergies presented with severely painful, watery eyes and blurred vision. She reported topical application of face-paint onto both upper eyelids prior to attending a Halloween party. She subsequently noticed a burning sensation, epiphora and misty vision within a few hours. On examination, bilateral large corneal epithelial defects were highlighted with fluorescein dye under cobalt-blue light. Antibiotic ointment, mydriatic and sodium ascorbate 10% eye-drops were given, and patient was advised to keep the eyelids shut to promote healing. No corneal defects were visible by day 4 and the patient was discharged with vision recovering to normal levels.
