Accurate visualization of the tumor base by diaphanoscopy is essential for optimal placement of a ruthenium plaque. Depending on the localization of the tumor, dissection of one or more of the rectus muscles is necessary during placement of the plaque or during the course of protracted irradiation. Orthoptic investigations were performed to evaluate the cause of motility disorders and to follow up the functional outcome. In 13 patients (out of 30) who underwent ruthenium-106 therapy for uveal melanomas, one or more muscles had to be dissected during placement of the plaque and were reinserted in the same operation or after removal of the applicator. In 4 cases rectus muscles had to be shifted and were replaced after the irradiation. There were 5 patients who developed motility disorders with double vision. All of them were orthophoric within 6 months without surgery.
透照法准确显示肿瘤基底对于钌板的最佳放置至关重要。根据肿瘤的位置，在放置钌板期间或长期照射过程中，需要对一条或多条直肌进行解剖。进行了视轴矫正检查以评估运动障碍的原因并跟踪功能结果。在30例接受钌 - 106治疗葡萄膜黑色素瘤的患者中，有13例在放置钌板期间必须解剖一条或多条肌肉，并在同一次手术中或取出敷贴器后重新植入。在4例患者中，直肌必须移位，并在照射后进行复位。有5例患者出现了伴有复视的运动障碍。他们所有人在6个月内未经手术即恢复了正视。
