Transient hypotony is hypothesized to be due to the creation of a cyclodialysis cleft which might extend beyond the external diameter of the CyPass [52].
(15) Other reported causes of glaucoma in raptors are traumatic iridodialysis and cyclodialysis (13); neither of which was observed in the present case, and primary glaucoma, (11) which would not be permanently corrected with short-term medical therapy as was the case in the current report.
A cyclodialysis cleft can also occur following trauma (which produces a direct channel between the suprachoroidal space and the anterior chamber) and can be a cabsu off a lowering of IOP.
Although I did not find evidence of cyclodialysis or dissociation of the pectinate ligaments of the iridocorneal angle in our cases, iOCT can be used to elucidate the mechanism of the phenomenon reported by Akagi et al.
He bisected the nucleus in the anterior chamber using a sharpened cyclodialysis spatula.
In general, eyes from raptor species with intraocular inflammatory lesions have significantly lower intraocular pressure (mean [+ or -] SD, 7.4 [+ or -] 4.6 mm Hg) than normal eyes (mean [+ or -] SD, 15.6 [+ or -] 3.4 mm Hg), and eyes with iridodialysis or cyclodialysis have higher intraocular pressure (mean [+ or -] SD, 35.4 [+ or -] 12.2 mm Hg).
Cyclodialysis: An opening between the anterior chamber and subarachnoid space, which allows passage of intra ocular fluid and reduces intra ocular pressure
Several mechanisms of action were proposed to explain the final IOP lowering after HIFU, such as localized destruction of the ciliary-pigmented and nonpigmented epithelium, atrophy of the ciliary muscle, cyclodialysis cleft, and scleral thinning [11-13, 83].
Spaeth (1980) combined extraction of lens with trabeculectomy, partial punch sclerectomy, iridenchleisis and cyclodialysis, but did not find a single combination suitable for all type of cases.
It can lead to hyphema, iridocyclitis, iris sphincter tears, iridodialysis, cyclodialysis, lens subluxation, angle recession, retinal tear or dialysis, retinal detachment, vitreous hemorrhage or choroidal rupture.
