毛细血管无灌注是糖尿病性视网膜病变缺血的一个信号。以往认为小范围受累可有再生血管形成,而大范围受累是不可逆的。作者报告1例增殖性视网膜病变,在广泛光凝后有大范围再生血管形成。 病例:33岁,男性。患糖尿病24年。用胰岛素及饮食治疗,病情控制较好。9年后发现有糖尿病性视网膜病变,周边网膜有新生血管。伴有周围神经炎及手指强直症状。 Capillary non-perfusion is a sign of ischemia in diabetic retinopathy. In the past that a small area may have involved in the formation of regenerative blood vessels, and a wide range of involvement is irreversible. The authors report a case of proliferative retinopathy with extensive revascularization after extensive photocoagulation. Case: 33 years old, male. Suffering from diabetes for 24 years. With insulin and diet treatment, the disease control is better. Nine years after the discovery of diabetic retinopathy, peripheral retinal neovascularization. Accompanied by peripheral neuritis and finger stiffness symptoms.
