Purpose: To report our diagnostic ultrasound-based approach and surgical strategy in a case of severe blunt trauma with complete hyphema, 270° iris disinsertion, and traumatic subluxated cataract. Case Report: A 70-year-old male was referred to our hospital for a blunt trauma in his right eye. A complete examination revealed visual acuity consisting in light perception, a complete hyphema, and an intraocular pressure of 45 mm Hg with moderate pain. Our diagnostic approached was ultrasound based with B-scan examination showing some vitreous hemorrhage and ultrasound biomicroscopy showing a large iris disinsertion of 270° with the iris entirely dislocated in the inferior sector of the anterior chamber. The patient was hospitalized and a systemic and topical treatment was started to lower intraocular pressure. Our surgery consisted in a single-step approach with removal of traumatic cataract with scleral fixation of an intraocular lens and iridoplasty. Conclusion: In our patient, the single-step surgery, supported by anterior and posterior ultrasound imaging, achieved a satisfactory anatomical and functional outcome.

Purpose. To compareab internoandab externoscleral fixation of posterior chamber intraocular lenses (PCIOL) using ultrasound biomicroscopy (UBM).Methods. Randomized patients underwentab externoorab internoscleral fixation of a PCIOL. Ultrasound biomicroscopy was performed 3 to 6 months postoperatively, to determine PCIOL centration, IOL distance to the iris at 12, 3, 6, and 9 hours, and haptics placement in relation to the ciliary sulcus.Results. Fifteen patients were enrolled in the study. Theab externotechnique was used in 7 eyes (46.6%) and theab internoin 8 eyes (53.3%). In theab externotechnique, 14 haptics were located: 4 (28.57%) in the ciliary sulcus; 2 (14.28%) anterior to the sulcus; and 8 (57.14%) posterior to the sulcus, 6 in the ciliary body and 2 posterior to the ciliary body. In theab internogroup, 4 haptics (25.0%) were in the ciliary sulcus, 2 (12.50%) anterior to the sulcus, and 10 (75.0%) posterior to the sulcus, 4 in the ciliary body and 6 posterior to the ciliary body.Conclusions.Ab externoandab internoscleral fixation techniques presented similar results in haptic placement.Ab externotechnique presented higher vertical tilt when compared to theab interno.

Anatomic Locations

Iris pigment epithelial (IPE) cysts are a subset of iris cysts that arise from the IPE. They are spontaneously erupting epithelial-lined cavities that are found in various anatomic locations of the iris, including the iris pupillary margin, midzone, periphery, and free floating in the vitreous or anterior chamber. We report the case of an asymptomatic 13-year-old boy with an incidental finding of a dislodged anterior chamber cyst diagnosed on routine examination. Modern multimodal image analysis of the cyst including anterior segment optical coherence tomography and ultrasound biomicroscopy (UBM) was utilized to characterize the microstructural anatomy of the lesion. The patient was managed conservatively without complications. Cysts of the IPE typically do not affect vision or ocular health and can be monitored and observed after ascertaining no associated malignancy. Initial diagnostic investigation can include UBM and anterior segment optical coherence tomography. Intervention should be reserved only for cases where the cyst growth leads to obstruction of the visual axis and/or other secondary complications.

<b><i>Introduction:</i></b> Ultrasound biomicroscopy (UBM) is the only widely used method for the evaluation of anterior uveal melanoma (AUM). <b><i>Objective:</i></b> Documentation of regression of AUM treated with ruthenium-106 (Ru-106) plaque types CCB and CCC using UBM. <b><i>Methods:</i></b> This single institution-based retrospective case series involved 10 Caucasian patients with AUM followed after brachytherapy with UBM from January 2014 until February 2019. The largest prominence of the tumor perpendicular to the sclera or the cornea (including scleral/corneal thickness) (<i>D</i>) and the largest basal dimension (<i>B</i>) were measured in millimeters with UBM for all patients prior to the brachytherapy and at 4-month interval follow-up. Tumor regression was calculated as a percentage of decrease in the initial <i>D</i> and <i>B</i> values. <b><i>Results:</i></b> The study involved 10 patients with a mean age of 64.4 years (yr) (range 46–80 yr). <i>D</i> ranged from 1.82 to 5.5 mm (median 2.99 mm) and <i>B</i> from 2.32 to 12.38 mm (median 4.18 mm). The apical radiation dose in all patients was 100 Gy. The median follow-up was 42.02 months. Regression for <i>D</i> was 21.11 ± 13.66%, 31.09 ± 14.66%, and 34.92 ± 19.86% at 1st, 2nd, and 3rd year of the follow-up, respectively, while for <i>B</i> it was 21.58 ± 16.05%, 28.98 ± 17.71%, and 32.06 ± 18.96%, respectively. Tumor recurrence was documented in 2/10 patients. <b><i>Conclusion:</i></b> The major regression of AUM, treated with Ru-106 plaque types CCB and CCC, was documented in the first 2 years after brachytherapy in our study group. In the following years, only minimal regression was documented that warns of the need for close monitoring and active search for local recurrences.
