Use of beta radiation to control I.O.P.

ABSTRACT

The use of ophthalmic applicator containing Strontium-90 beta ray was used to bring about a change in I.O.P. by its effect on the ciliary body. The change in I.O.P. depends on the degree of damage done to the ciliary body. The study showed that the change in I.O.P. was directly proportional to the intensity of beta rays application - higher the dose of beta radiation more was the damage and more the reduction in I.O.P.
