Plaque Brachytherapy

A 47-year-old man presented with profound loss of vision in right eye and relative afferent pupillary defect. On fundus examination, posterior pole details were obscured due to dense vitreous haemorrhage. B-scan ultrasonography was performed that revealed a mushroom-shaped hyperechoic lesion with medium internal reflectivity on A-scan ultrasonography. After performing contrast-enhanced MRI of the orbit, a diagnosis of choroidal melanoma was established. Patient was managed using plaque brachytherapy based on multiplanar MRI. This was followed 10 months later by pars plana vitrectomy and cataract extraction. Vision postoperatively improved to 20/60. A systematic clinical assessment along with supportive ancillary investigations augments diagnostic accuracy and reduces delay in definitive management.

A 49-year-old gentleman presented with a 1-day history of painful deterioration of vision in his right eye. He was lifting heavy weights just before this visual loss. On examination, his vision was perception of light in that eye, with a medically uncontrollable high intraocular pressure and hyphaema almost completely filling his anterior chamber. An ultrasound performed suggested a working diagnosis of a Valsalva related ‘eight ball’ bleed. After an anterior chamber washout, he had another episode of bleeding three days later. A pars plana vitrectomy was performed and the sample obtained was sent off to the laboratory, revealing a choroidal melanoma. Following enucleation, the histology confirmed a large necrotic spindle cell melanoma, with a haemorrhagic background. Fortunately, no liver metastasis was found. Since his diagnosis 3 years ago, he continues to be followed up in an artificial eye clinic and has regular liver scans under the care of his oncologist.

Purpose: Penetrating eye trauma with an intraocular foreign body is very frequent, especially in men in their productive age. Pars plana vitrectomy would be the standard surgical method at our department. However, in indicated cases (metallic intraocular bodies in the posterior eye segment in young patients with well transparent ocular media without detached ZSM and without any evident vitreoretinal traction) transscleral extraction of the intraocular foreign body is performed using the exo magnet, eventually endo magnet with a minimal PPV without PVD induction under the visual control of endo-illumination. Materials and Methods: Between June 2003 and June 2018, 66 eyes of 66 patients diagnosed with a penetrating eye trauma caused by an intraocular foreign body located in the posterior eye segment were treated. In 18 eyes (27,3 %) with a metallic foreign body in vitreous (body) or in retina, no PPV or a minimal PPV without PVD was used as a surgical method. In the remaining 48 eyes (72,7 %), a standard 20G, respectively 23G PPV method were used together with PVD induction and the foreign body extraction via endo or exo magnet. Conclusions: As demonstrated by our survey/study, in the cases of a thoroughly considered indication an experimented vitreoretinal surgeon can perform a safe NCT transscleral extraction from the posterior eye segment via exo magnet, eventually endo magnet under the visual control of a contact display system with a minimal PPV. Thereby, the surgeon can enhance the patient´s chance to preserve their own lens and its accommodative abilities as well as reduce the risk of further surgical interventions of the afflicted eye.
