Transscleral cyclocoagulation using a neodymium:YAG laser.

A series of pigmented rabbit eyes were treated with pulsed 10 msec (free running mode) neodymium:YAG laser burns to achieve transscleral cyclocoagulation. Grossly evident burns were created in the ciliary body with laser pulses of 1.5 joules of energy. Sustained reduction in intraocular pressure was obtained when 30 such laser burns were made in an eye.
