—One of the chief disadvantages of transpupillary argon laser cyclophotocoagulation is the inability to properly visualize enough ciliary processes for treatment. By using an indentation funnel^1,2 and tilting it so that the indentation protuberance indents the ciliary body, all ciliary processes can be visualized and treated in virtually any eye with a dilatable pupil.

The same placement of the indentation funnel (with the protuberance indenting the ciliary body) causes a marked deepening of the anterior chamber. This deepening is so profound that a gonioplasty is no longer necessary in neodymium (Nd)-YAG sclerostomy.³ (If a gonioplasty is not performed in Nd-YAG sclerostomy, then Nd-YAG laser iridectomy should be performed at the end of the procedure.) The indentation funnel is so helpful in Nd-YAG sclerostomy that it is not considered required in all cases, whether gonioplasty is performed or not. . . . [Full Text PDF of this Article]
