Reduction of ocular lens dosage in dacrocystography.
Irradiation of the lens of the eye in dacrocystography is largely avoidable. We have measured the lens dosage in bilateral dacrocystography in vivo and in a phantom. We describe simple protective measures which can reduce the lens dosage by over 95% to less than one mGy.
