AIM:To analyse the risk factors of age,sex,course,best corrected visual acuity(BCVA),diopter and fundus features of high myopes with progressive high myopia.·METHODS:A total of 167 patients with high myopes were categorized into four groups:group 1,age of 29 years or younger;group 2,between the age of 30 to 49 years;group 3,between the age of 50 to 69 years and group 4,age of 70 years or older.The refractive errors of all patients were measured without cycloplegia with an autorefractometer.Data of the spherical equivalent(SE) of the refractive errors in diopters (D)and fundus examed by direct ophthalmoscope were used in statistical analyses.·RESULTS:The number of female was statistically larger than that of male(P<0.01),also the disease course was correlated to the age.The visual acuity of high myopes significantly decreased as they grew older including the higher incidence of lacquer cracker,submacular hemorrhage,Fuchs spots,chorioretinal atrophy.·CONCLUSION:Female maybe a risk factor of high myopia,advanced age is an important factor of visual acuity decrease.High myopes ought to be treated early to delay the progress of myopia and development of macular degeneration.
