Search for: [Abstract = "In 72 patients \(47.7%\) treated with Ru\-106 isotope and in 152 patients \(89.4%\) treated with I\-125 isotope the visual acuity after the treatment was less than 0.1. In patients with a good visual acuity before the treatment \(0.5\-1\-0\) the acuity deteriorated in 37 individuals \(59.7%\) treated with Ru\-106 and in 43 individuals \(95.6%\) treated with I\-125 isotope. In the same group of patients the visual acuity did not change after the treatment in 25 subjects \(40.3%\) who underwent Ru\-106 brachytherapy and in 2 subjects \(4.4%\) who underwent I\-125 brachytherapy. The analysis of the factors affecting the occurrence of the post\-treatment visual acuity of less than 0.1 revealed a negative influence of the type of applicator \(I\-125\), the height of the tumour \( 8 mm\), the size of the tumour according to the Collaborative Ocular Melanoma Study classification \(large tumours\), the radiation doseapplied to the tumour top \( 100 Gy\) and the presence of symptoms at the time of diagnosis.Ru\-106 and I\-125 brachytherapy is the method which allows effective local control of the disease \(Ru\-106 \-76% vs I\-125 \- 95.1%\) and does not worsen distant prognosis in reference to the occurrence of metastases \(Ru\-106 \-14.6% vs I\-125 \- 15.1%\). In comparison to other available methods of treatment, it is a recognized and a commonly used procedure in the treatment of uveal melanoma. Due to this method the eye can be preserved in a large number of patients \(Ru\-106 \- 86% vs I\-125 \- 88.8%\) and the functional visual acuity can be retained in a considerable number of patients \(Ru\-106 \- 52.4% vs I\-125 – 10.6%\), which is significant in assessing the psychological and social aspects of the procedure. The results obtained in our centre, presented in my dissertation, remain consistent with the results offered by other authors in the field."]
