Objective: To study the incidence of visual fatigue related factors , to explore its pathogenesis, syndrome type and its characteristics . Methods: 143 cases of patients with ocular visual fatigue syndrome and systemic investigations , according to the national diagnostic criteria summarized syndromes, combined with literature data for statistical classifications , summed up the law to identify characteristics of its etiology and pathogenesis , and make Syndromes . Results : 143 patients statistics show that as the mental fatigue significantly more than manual workers ; occurs in 25 to 50 years of age and more common in women . Prevalent in patients with refractive errors and longer- term use VDT ( video terminal ) phenomenon, respectively 65.73% and 78.32% ; refractive errors visual fatigue caused by astigmatism , accounting for 58.51% , followed by hyperopia ( 29.79% ) , myopia least ( 11.70% ) . Depending on the degree of fatigue with VDT usage time was positively correlated with BUT ( tear film break-up time ) , and a negative correlation between the range of fusion . TCM etiology visual fatigue Typing Class deficiency syndrome ( liver and kidney deficiency , spleen qi , blood deficiency ) of 92 cases, accounting for 64.34% ; empirical class syndrome ( liver qi stagnation , blood stasis , liver and gallbladder Huochi ) of 47 cases, accounting for 32.87% . Deficiency in the liver and kidney and spleen qi deficiency , accounted for 42.39% and 38.04% . Empirical dominated by qi stagnation , a total 28 cases , accounting for 59.57% . The study found a total of 80 cases were complicated with dry eyes , and various syndromes , the liver and gallbladder and liver Qi stagnation Huochi rates were 100% and 82.14% , significantly higher than other syndromes . Conclusion: visual fatigue Pathogenesis is still in line with modern medicine for the disease etiology and pathogenesis of understanding: that is, from the liver , kidney, spleen, heart dysfunction caused by four dirty , and found that factors in the pathogenesis of liver Qi stagnation occupy an important position , consider the modern state of existence are closely related, should be stressed.
