Abstract:
AIM:To observe the clinical curative effect of different duration of retinal vein occlusion ( RVO ) by laser photocoagulation treatment, discuss the timing of the RVO laser photocoagulation treatment, provide the basis for clinical choice of RVO photocoagulation treatment time.
METHODS: Retrospective analysis. Line selection retinal laser photocoagulation treatment for 103 cases (103 eyes) with RVO, patients were divided into three groups according to the onset time. In group A (46 eyes), course≤ 1mo, 28 eyes with branch retinal vein occlusion ( BRVO ) , 18 eyes with central retinal vein occlusion ( CRVO);30 eyes were ischemic RVO, 16 eyes were non-ischemic RVO. In group B (38 eyes), 1mo RESULTS: The best corrected visual acuity improved rate, retinal hemorrhage, macular edema, absorption, macular center concave thickness decreased of patients with different course after RVO photocoagulation treatment, the early group was better than that of the late, non-ischemic RVO was better than that of ischemic RVO, laser photocoagulation treatment effect BRVO was better than that of CRVO and the difference was statistically significant (P<0. 05).
CONCLUSION:RVO laser photocoagulation in the early intervention treatment can accelerate the retinal hemorrhage, macular edema, absorption, effectively protect the patient's existing vision, improve the long-term vision, and has a certain clinical practical significance.
