In this study, we propose a new method for evaluating the functional results based on the sizes of phosphenes that the patient drew which were then digitalized. We also describe the methodology of psychological testing and support for a deaf-blind patient.
A 59-year-old man with retinitis pigmentosa and hearing loss (clinical Usher syndrome) underwent surgery to implant the Argus II retinal prosthesis system in his right eye.
Correlation analysis showed a weak dependency between the size of a phosphene and the perceptual threshold. Significant correlations between a phosphene and the height of the interface, impedance or retinal thickness was not found. The patient with the retinal prosthesis felt more independent and confident, and more healthy. This is the first case of retinal implant surgery in Russia.
The results of this study add to the understanding in the field of retinal implants functioning. The experience of the successful rehabilitation of the deaf-blind patient after implantation of Argus II allowed us to design a methodology that can be used in future similar cases.
在这项研究中，我们提出了一种新的方法，基于患者数字化绘制的光幻视大小来评估功能结果。我们还描述了心理测试的方法和对一位聋盲患者的支持。
一位 59 岁的男性患有视网膜色素变性和听力损失（临床乌谢尔综合征），接受了 Argus II 视网膜假体系统右眼植入手术。
相关分析显示光幻视大小与感知阈值之间存在弱相关性。未发现光幻视与界面高度、阻抗或视网膜厚度之间存在显著相关性。接受视网膜假体的患者感到更加独立和自信，更加健康。这是俄罗斯首例视网膜植入手术。
本研究的结果增加了对视网膜植入物功能领域的理解。成功为 Argus II 植入后的聋盲患者进行康复的经验使我们能够设计出一种可用于未来类似病例的方法。
