Abstract:
Central retinal vein occlusion(CRVO) and branch retinal vein occlusion(BRVO) are the most common retinal vascular diseases. Althouht the pathogenesis of these two dieseases are different, the clinical features are similiar. In this paper, we studied on several factors such as sex, age, laterality, refractive error, intraocular pressure(IOP) and, systemic diseases(56 eyes of CRVO group and 128 eyes of BRVO group). In BRVO hroup, female, above 50 years old, bilaterality and hyperopia(above +3.0D) are more frequent than in CRVO group. In CRVO group, high IOP and below 40 years old are more frequent than in BRVO group. The hing incidence of female in BRVO group(P=0.034) and the high incidence of high IOP in CRVO group(P=0.011) are statistically significant. Diabetes melitus, glucose intolerance, tuberculosis, and syphilis are more frequently associated in CRVO group than in BRVO group, whereas hypertension and heart disease are more frequently associated in BRVO group. An abnormal level in CRP, VDRL and PTT are higher in CRVO group than in BRVO. On the other hand, the incidences of abnormal lipid profile, Hb A2 fraction and RA are higher in BRVO group than in CRVO. In cases of CRVO, the incidence of hypertension is higher in patients of 50 years old or older than in patients do 49 years old or younger, In cases of BRVO, the incidence of heart disease in patients of 50 years old or older is higher than in patients of 49 years old or younger, which both diseases are statistically significant(P<0.05).
