| Thrombosed Iris Varix (Ultrasound Biomicroscopy) | |
| Ultrasound Biomicroscopy: circumscribed mass of the iris stroma. Patient:57 years of age, male, BCVA 0.7, IOP 17. Ocular Medical History: sometimes hyphema with increased IOP. General Medical History: arterial hypertension. Main Complaint: IOP peaks of 40mmHg Purpose: to present a thrombosed iris varix. Methods: Colour Photography Anterior Segment, Ultrasound biomicroscopy, Fluorescence Angiography of Iris. Findings: Colour Photography Anterior Segment: dark red iris mass of 2mm. Ultrasound Biomicroscopy: circumscribed mass of the iris stroma. Fluorescence Angiography of Iris: no perfusion in area of iridal mass, regular perfusion in iridal meshwork. Discussion: Iris varix is rare and little is known about its clinical characteristics. Iris varix should be included in the differential diagnosis of iris melanoma. Shields et al. (1) reported a case , that because of suspicion for melanoma, it was removed by sector iridectomy. Histopathologic examination disclosed an extensive focus of stromal hemorrhage, partially surrounded by endothelial cells that showed immunoreactivity to vascular markers.
