An ophthalmic radiation device having a substantially light-transparent wand configured to emit light propagating through the wand light from a series of illumination ports at least partially circumscribing a radioactive source disposed in the holder, thereby providing a visual reference for identifying a position of the radioactive source. Embodiments are directed at effectively directing light from a light source through the body of the wand to illumination ports by using the wand body itself as the light guide. The illumination ports are used as reference points by a medical practitioner to facilitate placing the device into a correct treatment position.
