中文摘要：

糖尿病性视网膜病变是患者致盲的主要疾病之一，定期的视网膜病变筛查是及时发现病变并治疗的唯一有效方法，而糖尿病性视网膜病变的远程筛查则有助于提高患者的筛查依从性。为此，本文对远程糖尿病性视网膜病变筛查系统进行分析，并重点提出系统远程操控模块的设计方案。系统远程操控模块由串口通信模块、操控平台及上位机通信程序3部分组成，实现了对眼底照相机的远程操控。通过测试，本方案所构建的远程操控模块具有结构简单，易安装且通用性较好等特点。

英文摘要：

Diabetic retinopathy is one of main diseases which lead to blindness. Regular screening for diabetic retinopathy is the only effective way for detection and treatment in time. Tele-screening for diabetic retinopathy will help patients to improve compliance with screening. Therefore, this paper analyzes the tele-screening system for diabetic retinopathy, and emphatically puts forward a design scheme of remote operation module, which is consisted of serial communication module, operation platform and communication program of computer, and realizes remote operation of fundus camera. Through the test, the module built by this scheme has advantages of simple structure, easy installation and universal property and so on.
