Objective: To describe the clinical characteristics of high myopia and recommend the way to examine the eyes of high myopia. Method: observation, non comparative study, 60 high myopia eyes presented to VNIO from May 2007 to October 2008. Data collected included: age, sex, IOP, uncorrected visual acuity (UCVA), best spectacle corrected visual acuity (BSCVA), refraction, White to white, comeal refraction, comeal radius, endothelial cell, ocular length by echography and IOL Master, ERG... Results: average age was 25,28 + or - 0.938, 40.6 percent was male and 59.4 percent was women, IOP was 18.48 + or - 1.33mm Hg, ACD was 3.13 + or - 0.34mm, central comea thickness was 530 + or - 500, white to white was 11.44 + or - 0.32mm, comeal radius was 7.61 + or - 0.04mm, comeal refraction was 44.46 + or - 0.19, endothelial cells were 3055 + or - 26.45 cells/mm2, ocular length by ultra and IOL Master were 28.27 + or - 0.25mm and 28.60 + or - 0.26mm. UCVA was CF 1.5m, no one more than 1/10. BSCVA was 3.7/10. The mean manifest refractive sphere was 12.44D + or - 5.61D, the mean manifest refractive cylinder was 2.390 + or - 1.660, the mean manifest refractive spherical equivalent was 13.30 + or - 5.760. Retinal function: 7.5 percent ERG non-recorded type (Great decrease), 65 percent ERG moderate decrease, 27.5 percent ERG normal. 26/60 eyes were retinal periphery degeneration with high risk of retinal detachment, which had to laser. Conclusion: Almost the clinical and non clinical characteristics of high myopia in this study corresponded with previous ones among Caucasians and Asians. This study to recommend the way to examine, survey and treatment for high myopia.
