ABSTRACT
Objective:To study the effect of breviscapine on visual function of the patients with primary open-angle glaucoma after filtration surgery. Methods:Twenty-nine cases (42 eyes) of patients with primary open-angle glaucoma at middle and late stage after filtration surgery were selected and randomly divided into the experimental group and the control group according to the defect degree of visual field. The 15 patients (21 eyes) in the experimengtal group ( TG) were intravenously injected 250ml saline containing 50mg breviscapine, while the 14 patients (21 eyes) in the control group (CG) were intravenously injected 250ml saline containing 1g vita-min C. The treatment course was 2 weeks followed by one-week withdrawal. After three treatment courses, the visual function in the two groups was investigated and compared before and after the treatment. Results:After the treatment, the visual field defect value and the thickness of retinal nerve fiber layer of the patients in TG were both better than those before the treatment (P<0. 01,P<0. 05). The values of visual acuity and visual field defect of the patients in TG were significantly better than those of the patients in CG ( P<0. 05, P<0. 01). Conclusion:After intraocular pressure is controlled, breviscapine injection can reduce the vision damage of patients with primary open-angle glaucoma at middle and late stage after filtration surgery and improve the visual field defect.
ABSTRACT
@# ObjectiveTo study the clinical features and pathogenesis of ophthalmoplegia in senile patients with diabetes, and access the possibility of its development.MethodsBesides routine ophthalmologic and ocular muscle examination, general and laboratory examinations were also done. Some patients were diagnosed also with the help of image processing.ResultsMonocular involvement happened in all 21 patients. 12 patients suffered from oculomotor nerve paralysis, 5 abducent nerve paralysis, 3 trochlearis nerve paralysis, and 1 compound nerve paralysis. Among these patients with complete oculomotor nerve panalysis, no papillary change appeared.Conclusions Microvascular pathologic change may be the pathogenetic basis of ophthalmoplegia for senile diabetic patients. Its prognosis is favorable if reasonable treatment is made.
