Abstract

A modified form of penetrating cyclodiathermy has been employed as a last resort operation in refractory glaucoma. The operation was intended to produce external filtration from the vitreous cavity through the pars plana at a few points, hoping to reproduce what P. A. Chandler has observed to occur fortuitously in rare cases, rather than attempting to suppress aqueous formation by destruction of the ciliary body, as usually intended in the past. Results from 100 of these operations performed on 26 adults and 27 children indicate approximately a 5% chance of obtaining lasting useful reduction of the intraocular pressure in this way, and about an equal chance of inducing phthisis.
