Embodiment

[0016] A research method for the relationship between the range of laser photocoagulation and the prognosis of diabetic retinopathy. Diabetic retinopathy was diagnosed in the Department of Ophthalmology of Tangdu Hospital affiliated to 280 patients (386 eyes) who received laser treatment. Diabetic retinopathy and macular edema are graded according to the 2002 International Diabetic Retinopathy Grading Standard, and fundus fluorescein angiography (FFA) examination shows large areas of non-perfusion and neovascularization are indications for retinal laser treatment.

Abstract

The invention relates to a research method for the relation between a laser photocoagulation range and a diabetic retinopathy prognosis, the purpose of which is to provide an important control strategy for the timing and method of treating the diabetic retinopathy with laser by comparatively analyzing the relation between the laser photocoagulation range and the diabetic retinopathy prognosis. By comparing different laser modes in three months of laser treatment, the research method discovers that the visual field defect of a diseased eye is obviously caused by panretinal laser photocoagulation while the retinal function outside the macular region is protected by local retinal laser photocoagulation and quadrant laser photocoagulation. The research proves that the quadrant retinal laser photocoagulation carried out on the diseased region of the retina can remarkably improve the anoxic state of the retina, prevent the growth of new blood vessels on the retina and protect the visual function of the macular region.

Description

technical field [0001] The invention relates to a research method for the relationship between the range of laser photocoagulation and the prognosis of diabetic retinopathy, which belongs to the technical field of pathology. Background technique [0002] With the increase in the incidence of diabetes, the incidence of diabetic retinopathy is also increasing. At present, diabetic retinopathy has become the first blinding eye disease among working people. In cities, 50% of diabetic patients will develop diabetic retinopathy. 150 million people worldwide suffer from diabetic retinopathy, and the number of people with diabetic retinopathy will double by 2025. [0003] Diabetic retinopathy is an important cause of blindness in patients over the age of 50 and is the leading cause of blindness in the West. In recent years, with the change of people's diet and the aging of the population, the incidence of diabetic retinopathy is increasing day by day. The importance of the treat...
