Parameters of accommodative and vergence systems and the development of late-onset myopia.

摘要: Purpose. To evaluate whether the characteristics of oculomotor system are related to development late-onset myopia. Methods. Forty-four college students were followed for 2 3 years. When recruited, 33 44 subjects had emmetropia whereas remainder (N = 11) myopia (LOM). For each subject, dark-focus, dark-vergence, response AC/A, and CA/C ratios, manifest refraction measured at 6-month intervals. Results. The mean dark-focus AC/A ratios 6) who started with became myopic higher than 25) remained emmetropic. These values presented before refractions exceeded -0.50 D. Interestingly, 7 11 LOM whose increased displayed dark-vergence lower Conclusion. found among seems be a consequence However, might eventually develop in person relatively high and/or values. Therefore, may predictors Invest Ophthalmol Vis Sci. 1995 ;36 :1737-1742.
