21. Imaging the microcirculation of untreated and treated human choroidal melanomas.

Author

Abstract

Introduction: Histologically demonstrable microcirculation patterns (microcirculation pattern) of human choroidal melanomas have prognostic significance for the patient. We report on our experience in imaging these microcirculation pattern in vivo using simultaneous confocal Fluorescein (FA)- and Indocyaninegreen (ICG) angiography before and after brachytherapy. Patients and methods: The simultaneously procuredconfocal FA- and ICG angiograms of 50 patients with untreated choroidal melanomaswere studied for the visibility of microcirculation pattern. Patients were also followedwith simultaneous FA/ICG after brachytherapy. Results: Confocal FA disclosed signs of tumor vascularization in 12 (24%) of the 50 examined patients but microcirculation pattern only in 3 patients (6%). In contrast, simultaneously obtained confocal ICG disclosed microcirculation pattern in 47 patients (94%). In 10 (77%) of the 13 patients the tumor microcirculation changed considerably after brachytherapy: Distortion, thickening, thinning, as well as complete obliteration of vessels could be observed. Conclusion: Histologically demonstrated microcirculation pattern can be imaged in vivo. This offers the possibility to assess the likely biologic behavior of the individual tumor without the need for obtaining a cytologic or histologic specimen via enucleation or fine-needle biopsy. Confocal ICG angiogiography images microcirculation pattern better than FA which can be explained by the different absorption-, fluorescence- and exudation-characteristics ICG. Follow-up with confocal ICG of choroidal melanomas after brachytherapy shows different features and allows for visualization of themicrocirculation reaction to the treatment which might be a useful tool for studying the effects of future anti-angiogenesis based tumor therapies.

Abstract

PURPOSE: To report the occurence of neurotrophic corneal defects in amn after ciliary body ablation with the diode laser. METHODS: Case reports. RESULT: Neurotrophic keratitis, previously associated with cyclocryotherapy, may also be associated with ciliary body ablation with a contact diode laser. CONCLUSION: Practitioners who use the diode laser for ciliary body ablation should be aware of neurotrophic keratitis as a possible complication, especially because the patient population receiving this therapy may have diabetes, chronic eye inflammation, or other conditions predisposing to compromised corneal innervation, which is necessary for epithelial integrity.
