Typical ultrasound biomicroscopic findings seen in ocular hypotony

Detailed imaging of the ciliary body region by means of ultrasound biomicroscopy can provide information that is crucial for further treatment whereas clinical evaluation and 10-MHz standard B scan are less helpful. BACKGROUND: To evaluate the suitability of ultrasound biomicroscopy (UBM) for elucidating the causes of ocular hypotony. PATIENTS AND METHODS: A retrospective chart review was performed to determine the usefulness of UBM in the evaluation of ocular hypotony. UBM, B scan, and a detailed clinical examination had been performed. Sixty patient charts with prolonged ocular hypotony of different causes were reviewed from January 1994 to December 1998. The information obtained by the UBM was classified into three groups: 'diagnostic' (group 1), 'helpful' (group 2), 'not helpful' (group 3). RESULTS: Of the 60 eyes, 45 UBM examinations (75%) were in group 1, 9 eyes (15%) were assigned to group 2 and 6 eyes (10%) were in group 3. The duration of hypotony had no influence. CONCLUSION: In cases of ocular hypotony, the cause was related to ciliary body pathologies in 80%. Only UBM could distinguish tractional from dehiscence ciliary body detachment which required a different management approach. UBM with its high resolution imaging of the anterior segment - including the ciliary body - is highly suitable for diagnostic clarification.     

Ultrasound Biomiscroscopy in the diagnosis and management of cyclodialysis clefts

PURPOSE: To report the role of Ultrasound Biomicroscopy (UBM) as a tool in the diagnosis and management of cyclodialysis clefts. METHODS: Six eyes of 6 patients with hypotony and suspected or diagnosed cyclodialysis clefts underwent UBM evaluation. Post-treatment UBM was performed in four eyes to assess the effect of the treatment. RESULTS: Cyclodialysis clefts were accurately diagnosed and delineated in 6 eyes by UBM. Complete closure was documented after treatment in 3 eyes, and a residual cleft in one eye. These findings were compared to gonioscopic findings. CONCLUSIONS: UBM is a safe, accurate and noninvasive diagnostic tool in the diagnosis of cyclodialysis clefts and is of particular use when other conventional methods of diagnosis are inconclusive.     

Closure of persistent cyclodialysis cleft using the haptics of the intraocular lens

PURPOSE: To evaluate a technique for ab-interno repair of cyclodialysis cleft in conjunction with placement of an intraocular lens (IOL). DESIGN: Interventional case reports. METHODS: setting: Clinical practice. patients: Two eyes of two patients, one phakic and one aphakic, present with hypotony secondary to traumatic cyclodialysis cleft. intervention: A single piece all-polymethyl methacrylate intraocular lens (PMMA IOL) 13.5 mm in diameter was placed in the ciliary sulcus with the haptics placed in the area of cyclodialysis cleft during cataract surgery and secondary placement of IOL. main outcome measures: Intraocular pressure (IOP). RESULTS: Hypotony resolved in both patients on the first postoperative day and the IOP was maintained above 10 mm Hg for more then 36 months postoperatively. CONCLUSIONS: In the setting of hypotony from a traumatic cyclodialysis cleft, the haptics of an IOL can be used as an internal cerclage during cataract or secondary IOL surgery to effectively close the cleft by direct apposition of the ciliary body to the overlying sclera.

Four cases of hypotony maculopathy caused by traumatic cyclodialysis and treated by vitrectomy, cryotherapy, and gas tamponade

Purpose We report our results in four cases of hypotony maculopathy caused by traumatic cyclodialysis and treated by combined vitrectomy and cataract surgery.Methods The patients' visual acuities ranged from light perception to 0.2, and intraocular pressures ranged from 4.7 to 5.7 mmHg (mean 5.1 mmHg) before surgery. Ultrasound biomicroscopy (UBM) revealed cyclodialysis associated with ciliary body detachment of 180° to 360°. We performed combined vitrectomy and cataract surgery, with pars plana cryopexy for detached ciliary body and an SF₆ gas tamponade.Results Postoperative UBM showed that cyclodialysis and/or ciliary body detachment disappeared in the whole circumference of two eyes, while it partially remained at 15° in one eye and at 30° in one eye. Postoperative visual acuity ranged from 0.06 to 1.2, with IOP ranging from 9.0 to 14.7 mmHg (mean 12.2 mmHg).Conclusions Based on our results, we consider that the present combined therapy is highly reliable for closing and adhering traumatic cyclodialysis and normalizing hypotony.     

Intraocular hypotony: use of ultrasound biomicroscopy (UBM) for differential diagnosis and its schematic representation

OBJECTIVES: To determine the use of high-frequency ultrasound biomicroscopy (UBM) in the assessment of hypotony and in particular to determine the proportion of cases for which UBM contributed significant additional hitherto unaccessible information. PATIENTS AND METHODS: Ultrasound biomicroscopy was performed in a standard manner, using a Humphrey UBM 840 system (Humphrey Instruments, Inc., San Leandro, CA). UBM findings were analysed and the clinical relevance of UBM information was determined for the whole collective. RESULTS: Twelve patients with hypotony were examined. UBM findings contributed essential information that allowed to reach a diagnosis or that determined the therapeutic attitude in 10 of the 12 hypotonic patients. In two cases the cause of hypotony was tractional ciliary body detachment, in 5 cases it was post-inflammatory atrophy of the ciliary body, in 3 cases it was post-traumatic irido and cyclodialysis, in one case it was supraciliary and suprachoroidal effusion and in the last case it was due to uveal effusion syndrome. Based on these findings we established a schematic approach for hypotony. CONCLUSIONS: This procedure enabled us to assess the morphological changes found in patients with hypotony. In a majority of cases UBM was useful either to orient therapeutic intervention or to establish a diagnosis. On the base of our findings a schematic approach for hypotony, using UBM, was established.
