Since transpupillary thermotherapy (TTT) is currently gaining attention as an optional treatment for choroidal melanomas and hemangiomas, we sought to determine whether TTT is suitable for treatment of solitary choroidal metastasis at the posterior pole. We report on a patient with decreased vision due to a serous macular detachment in a eye with a solitary choroidal metastasis from breast carcinoma, who was managed by TTT. After two months of follow up, total re-absorption of the serous macular detachment was achieved and the patient recovered full visual acuity in the treated eye. The choroidal mass became atrophic and hyperpigmentation of the retinal pigment epithelium and retinal folds in the macular region were observed. After six months of TTT, the ocular picture remained unchanged. TTT can be considered an acceptable therapeutic option for solitary choroidal metastasis associated with serous retinal detachment.

The ProMRI Phase C study is a multicenter, prospective, single arm, non-randomized study to evaluate the clinical safety of the Biotronik ProMRI Iforia ICD system during MRI. Patients were enrolled after ICD implantation, with either dual chamber DR-T or single lead VR-T DX system. Study defined, non-diagnostic cardiac or thoracic spine MRI was performed at least 1 week after enrollment. ICDs were placed into MRI mode with VF detection/therapy programmed OFF prior to scan and restored to non-MRI mode after scan. Interrogation was performed before, immediately after, and one month post-MRI. The primary endpoints were: 1) ventricular pacing threshold increase >0.5 V from pre-MRI to one month post-MRI, 2) R wave amplitude decrease >50% from pre-MRI to one month post-MRI, or R wave amplitude <5 mV at one month post-MRI, and 3) MRI and ICD system relate...
