Motility assessment and clinical outcomes of a magnetically integrated microporous implant.

The purpose of this study was to evaluate the surgical technique, morbidity, and motility of a novel microporous, high-density, polyethylene implant with magnetic coupling of the prosthesis and implant. Four adult patients requiring enucleation underwent implantation of a microporous, high-density, polyethylene implant with an integrated stainless steel, titanium-coated post. The motility of a magnetically embedded prosthesis was assessed by measuring lateral prosthetic excursion using digital photography.

Macular retinoblastoma: evaluation of tumor control, local complications, and visual outcomes for eyes treated with chemotherapy and repetitive foveal laser ablation.

Objective: To determine tumor control rates, complication rates, and visual acuity (VA) for patients with macular retinoblastoma undergoing systemic chemotherapy and foveal diode laser ablation.

Design: Noncomparative retrospective case series.

Participants: All patients with retinoblastoma in the macula at the Bascom Palmer Eye Institute between 1991 and 2004 were evaluated.

Pars plana lensectomy and intraocular lens implantation in pediatric radiation-induced cataracts in retinoblastoma.

Objective: To investigate visual outcomes, surgical complications, and tumor recurrence among children with retinoblastoma (RB) undergoing pars plana lensectomy, vitrectomy, and simultaneous intraocular lens insertion for radiation-related cataract secondary to external beam radiotherapy (EBRT).

Design: Retrospective, noncomparative, consecutive case series.

Methods: The medical records for all patients treated with pars plana lensectomy, vitrectomy, and posterior chamber intraocular lens implantation for radiation-induced cataract after EBRT for RB at a single institution between January 1, 1990, and December 31, 2000, were reviewed.

External beam radiation "salvage" therapy in transgenic murine retinoblastoma.

Objective: To determine the efficacy of low-dose "salvage" external beam radiation therapy (EBRT) following failed subconjunctival carboplatin chemotherapy in a murine model of heritable retinoblastoma.

Methods: Eighty-four eyes from 8-week-old, simian virus 40, T-antigen-positive mice were treated with 6 serial subconjunctival carboplatin injections (100 microg/25 microL). At 12 weeks of age, 64 eyes received EBRT for a total dose of 480 (4.

Magnetically integrated microporous implant: safety and efficacy of secondary posting.

Objective: To evaluate the surgical technique and morbidity related to secondary posting of a previously implanted 12-mm microporous high-density polyethylene implant (MEDPOR) and the enhanced motility associated with magnetic coupling of the prosthesis and the implant in a rabbit model.

Methods: Eight New Zealand rabbits underwent primary evisceration surgery with implantation of a 12-mm microporous high-density polyethylene implant. At 6 weeks, a 4 x 6-mm stainless steel, titanium-coated post was secondarily inserted in 6 rabbit eyes using a bilevel incision.
