The Study Of Type Ⅱ Diabetic Retinopathy In-patients With Visual Impairment And Postoperative Effects

Diabetic retinopathy(DR) is one kind of disease of serious visual damage ,which easily ignored for it doesn't affect central vision at early times .If people miss the best therapeutic opportunity, it is hard to help them gain a satisfied healing efficiency. The more delay, the serious visual damage . Long time low acuity and blindness affects patients'health and life severely. Thus by analyzing preoperative , postoperative visual acuity and high risks of visual damage in DR patients,our study aims to deepen the recognition of DR and its risk factors,remind people the early diagnosis and therapy of diabetes and DR is the appropriate way to save visual acuity and raise the quality of life.Objective: To evaluate the visual damage and postoperative visual conditions in type 2 diabetic retinopathy patients.Methods: The clinical cases of 221 type 2 DR patients with 247 eyes who underwent vitrectomy in department of ophthalmology, the second hospital of Jilin university from Apr.2008 to Mar.2009 were retrospectively studied. According to the datum ,we analyze sex ,age , preoperative and postoperative visual acuity ,duration of diabetes ,clinical stages of DR, blood pressure, whether preoperative PRP(panretinal photo coagulation )and postoperative visual acuity improvement..Results: With the development of DR ,the patients'visual damage tends to deteriorate. Our study shows age and stage conditions of DR in-patients. The age of 50~60 group is the most, and the percentage is 50.23%. There are little relationship among duration , blood pressure, whether preoperative PRP and preoperative or postoperative visual acuity. But the clinical stage of diabetic retinopathy affects postoperative visual acuity improvement. The increase of postoperative visual acuity of DR IV and DR V stage is much higher than DR VI stage. The visual acuity improvement rate of DR IV stage is 80.56%,and DR V stage is 84.89%,while DR VI stage is 64%. Postoperative low vision rate is 40.49%, and blindness rate is 44.53%. Low vision and blindness patients are lower after vitrectomy, but it seems that most patients'visions are still impaired severely.Conclusions: DR, which seriously influences the patients'vision , can leads to a high risk of blindness. Although most of patients'visual acuity can be improved by operations, a quantity of patients yet suffer blindness and low vision. The treatment of diabetic eye complications includes not only local ocular therapy, but also comprehensive points to realize and prevent the harm of diabetes and its complications .Meanwhile , we must intensify the propaganda and education of diabetes ,adjust diet style, control blood glucose and BP strictly to decrease the visual damage of DR.The diagnosis and treatment of diabetes must be as early as possible. If DR or visual damage occurs , regularly examinations and positive methods are appropriate to defer the progress of disease. PRP and vitrectomy at early stage of PDR are also necessary to prevent unrecoverable visual damage.
