目前糖尿病性视网膜病变已成为成人继发性失明的重要原因之一。糖尿病病人一旦发生增殖性视网膜病变,出现神经胶质反应和新生血管,在五年内病程进展至视力完全丧失的机会高达50％,而且任何药物均难奏效。去除垂体前叶功能对若干病人乃是能够中断此种病程的唯一措施。1953年Poulsen首先介绍一例严重糖尿病性视网膜病变在发生垂体前叶机能减退症之后病情突然明显好转,指出垂体功能对病程的影响。1955年Lutt等首先采用垂体切除术治疗糖尿病性视网膜病变以来,迄今各家 Currently, diabetic retinopathy has become one of the important causes of adult secondary blindness. In diabetic patients with proliferative retinopathy, glial reactions and neovascularization occur, the course of disease within five years to the complete loss of vision opportunity up to 50%, and any drug is difficult to work. Removing the anterior pituitary function is the only measure that can interrupt this course for several patients. Poulsen first introduced in 1953 a case of severe diabetic retinopathy in the sudden onset of hypopituitarism after a sudden significant improvement in the condition, indicating the effect of pituitary function on the course. In 1955 Lutt and other first use of pituitary surgery to treat diabetic retinopathy, so far each house
