Abstract


Objective: branch retinal vein occlusion (BRVO) is the most common retinal vascular diseases, is a common clinical blinding eye disease . Complexity of its causes , risk factors and diverse, usually occurs in with hypertension, arteriosclerosis , diabetes and other systemic diseases of the elderly . Branch retinal vein occlusion in the pathogenesis of a variety of factors involved in the pathophysiological process , it is not very clear. This study investigated the branch retinal vein occlusion and anterior chamber depth and axial length relationship . Methods: randomly selected from March 2009 to October 2010 at the First Affiliated Hospital of Dalian Medical diagnosis and treatment of 45 patients ( 90 eyes ), BRVO eye 45 cases ( 45 eyes ) , come to my hospital examination in 45 cases ( no eye disease ) as a control group . Respect to their color fundus photography and fluorescein angiography (FFA) Check and groupings. BRVO eyes 45 eyes with group 1 , the contralateral eye ( eye health ) 45 eyes of group 2 , the control group 45 right for the group 3 , the control group 45 left for the group 4 . Optical coherence biometry -IOL Master of each group were measured axial length and anterior chamber depth , and for statistical analysis, the control group and the case group age and sex-matched . Results : BRVO group blocking the average axial length of the eye (22.69 ± 0.99) mm, the average axial length of the fellow eye (22.78 ± 1.24) mm, the statistical analysis , the difference was not statistically significant (t = 0.355, P> 0.05 ) ; eye control group mean axial length (23.38 ± 1.32) mm, left eye mean axial length (23.37 ± 1.27) mm, the difference was not statistically significant (t = 0.017, P> 0.05), BRVO group blocking eye axial length and the control group was significantly (t = -2.563, t = -2.663, P <0.05). BRVO group blocking the average eye anterior chamber depth (2.66 ± 0.26) mm, contralateral eye mean anterior chamber depth (2.65 ± 0.30) mm, the statistical analysis , the difference was not statistically significant (t = 0.089, P> 0.05) ; the control group mean anterior chamber depth of the right eye (2.56 ± 0.29) mm, left eye mean anterior chamber depth (2.59 ± 0.30) mm, the difference was not statistically significant (t = -0.592, P> 0.05), BRVO group blocking eye and anterior chamber depth control group showed no significant difference (t = 1.779, t = 1.778, P> 0.05). Conclusion : Short axial length may be a development branch retinal vein occlusion risk factors. Anterior chamber depth and branch retinal vein occlusion relations to be further confirmed.
