Trodd YR 1978 UL http://bjo.bmj.com/content/62/4/268.abstract AB Several techniques have been used to treat dry eye, to irrigate the eye surface, or to apply drugs in solution. The commonest method is to apply drops. But a technique is needed for giving solutions over long periods either as drops or continuously. The apparatus described here consists of a replaceable plastic tank under mechanical pressure attached to capillary tubing which is kept in contact with the inner canthus of the eye. It was found to alleviate symptoms in severe dry eye conditions not alleviated by other methods.
