·AIM:To observe the effect of differentiation of syndrome on early ischemic retinal vein occlusion after laser photocoagulation.METHODS:Totally 194 cases(214 eyes)with early ischemic retinal vein occlusion were randomly divided into control group,including 96 cases(102 eyes),and treatment group,including 98 cases(112 eyes).The control group was treated with Western medicine on the basis of retinal laser photocoagulation.The treatment group were differentiated into the syndromes of liver yang hyperactivity,qi stagnation and blood stasis,deficient spleen and weak qi,liver depression and bleeding due to blood-heat,then they were respectively given to differentiation of syndrome after laser treatment.RESULTS:In treatment group,34 eyes were recovered,68 eyes improved,10 eyes invalid,and the total effective rate was 91.1%.In control group,8 eyes were recovered,68 eyes improved,26 eyes invalid,and the total effective rate was 74.5%.The difference of clinical effect between the two groups was statistically significant(P<0.05).CONCLUSION:It is satisfactory to treat early ischemic retinal vein occlusion after laser photocoagulation therapy with differentiation of syndrome.
