Intraoperative sonographically assisted radioactive iodine 125 plaque brachytherapy for choroidal melanoma: visual acuity outcome.

Objectives: The purpose of this study was to present a retrospective series of cases from a single Canadian academic center assessing visual acuity outcomes after intraoperative sonographically assisted iodine 125 ((125)I) plaque brachytherapy treatment.

Methods: The cases of 28 patients (16 male and 12 female; mean age ± SD diagnosis, 62.3 ± 15 years) with choroidal melanoma treated with (125)I plaque brachytherapy using intraoperative sonography between 1997 and 2002 were reviewed.

Iodine-125 radiotherapy for choroidal melanoma.

The objective was to evaluate the effect of the gender, size, and tumor location at the time of the diagnosis on the regression response of choroidal melanoma following plaque radiotherapy treatment. The paper is a longitudinal prospective study of 28 patients diagnosed with choroidal melanoma at McGill University Health Centre from 1997 to 2002. All patients were treated with episcleral iodine-125 (I(125)) plaque radiotherapy.

Intra-operative echographic localization for radioactive ophthalmic plaques in choroidal melanoma.

The objectives were to evaluate the beneficial effect of intra-operative echographic plaque site localization and to assess the rate of complications of postplaque insertion. This paper is a descriptive study of 48 patients with choroidal melanoma who underwent iodine-125 (I(125)) or ruthenium-106 (Ru(106)) plaque radiotherapy with intra-operative echographic confirmation of plaque placement with the aid of a nonradioactive plaque (dummy) at McGill University Health Centre from 1997 to 2003. Patients' mean age was 63.

Visualization of posterior lens capsule integrity by 20-MHz ultrasound probe in ocular trauma.

Purpose: To evaluate the use of the 20-MHz ultrasound probe in facilitating visualization of the posterior lens capsule in ocular trauma.

Design: Interventional case report.

Methods: Serial examinations using 10-MHz, 20-MHz, and 50-MHz ultrasound technologies were performed on the anterior segment of the right eye of an 18-year-old man referred with a diagnosis of globe penetration and secondary traumatic cataract.

Ultrasound biomicroscopy of pseudophakic eyes with chronic postoperative inflammation.

Purpose: To evaluate the ultrasound biomicroscopy (UBM) findings in pseudophakic eyes with chronic noninfectious postoperative inflammation and discuss the use of the technique in these cases.

Setting: Uveitis Service, Department of Ophthalmology, McGill University, Montréal, Québec, Canada.

Methods: Fifty-four eyes of 51 patients with chronic noninfectious postoperative inflammation were prospectively evaluated between January 1998 and September 2001.

Ultrasound biomicroscopy of the Artisan phakic intraocular lens in hyperopic eyes.

Purpose: To study in situ the intraocular position of the Artisan iris-claw intraocular lens (IOL) (model 203) (Ophtec) in phakic hyperopic eyes using ultrasound biomicroscopy (UBM).

Methods: Echograms of the anterior chamber were taken preoperatively and 24 to 317 days postoperatively in 4 eyes implanted with the Artisan IOL (power +4.0 to +6.
