Histopathologic Findings of Ciliary Body Destructive Procedures

Arch Ophthalmol. 1986;104(11):1583. doi:10.1001/archopht.1986.01050230021004
Abstract

To the Editor.  —Recently Margo1 described the histologic effects of an unsuccessful focused ultrasound treatment for glaucoma. We should learn as much as possible from such valuable experience. For example, in this eye, why was the glaucoma not controlled? The author stated that in areas with "highly localized destruction" of the ciliary body, only the "posterior half of the pars plicata" was disorganized. Unfortunately, in the three photographs showing the pars plicata (Figs 1 through 3), two figures have little direct view of this structure and the third one (Fig 2) is too dark and set at too low a magnification to detect the details of the effect of treatment. Presumably, however, the protocol used in this eye did not destroy enough aqueous humor-forming capacity to normalize eye pressure; either the direction at which the instrument was aimed was too posterior (destroying only the posterior portion of the pars
