Anatomical Factors On The Retinal Branch Vein Occlusion In The Role

Objective:To 62 retinal branch by vein occlusion obstruction parts structure characteristic of patients with vision and follow-up analysis and the first sight of statistics, this paper explores its triggers in the importance of anatomical factors, thus for the future clinical diagnosis and prognosis assessment for reference. Methods:We retrospectively reviewed in January 2008 to December 2010 in XinJiang medical university first affiliated hospital of ophthalmic ward to accept treatment BRVO 62 cases patients (62 eye) and the same period BRVO patients (62 eye) of indirect ophthalmoscopy fluorescence angiography results, record two groups after extremely department arteriovenous cross quantity and overlapping relation, temporal side first move vein intersection and pan edge distance, the second isolated retinal arterial existence condition and BRVO patients with both the visio:n and follow-up eyesight, statistical analysis. Results:BRVO occurs in temporal on quadrant (percentage) in the trunk of a branch and the arteriovenous intersecting vascular, including vein after a crossover (85.5%), BRVO temporal lobe on the team first move vein intersection and plate margins average distance between 0.89±0.53 PD control on the temporal than the first move vein intersection and mycoplasma disk edge average distance 1.90±0.79 PD considerably shorter, the temporal lobe BRVO eye under the first move next branch vein intersection and plate margins average distance between 1.78±0.24 PD relatively control the first move vein intersection and mycoplasma disk edge average distance 2.09±0.64PD short, BRVO eye second isolated retinal arterial branch of quantity is less, BRVO contralateral eye a second isolated retinal arterial of BRVO patients than without a second isolated retinal arterial BRVO patients of both the vision and follow-up eyesight considerable improvement. Conclusion:Branch retinal vein occlusion occurs in temporal lateral trunk and a branch vascular junction especially after a cross, intravenous temporal side first move vein of crossing and plate margins distance too short and BRVO occurs with close relation, the second isolated retinal arterial branches of the existence of retinal branch vein occlusion may their vision has certain protective effect.
