Summary:
Purpose: to evaluate the volume of accommodation in students with the help of Tonoref III (Nidek, Japan) apparatus before and after the visual load, and also to identify the correlation of the volume of accommodation with the refraction indices and papilla size. Material and Methods. We investigated 204th year students of BSMU who passed the test of accommodation and refraction on the device Tonoref III (Nidek, Japan) 10 minutes before and immediately after a lecture. Results. We identified that the accumulative response after the exercise was weakened and clinical refraction was increased. The accommodation afterthe load was decreased. By reducing the amount of accommodation revealed an increase in the diameter of a pupil. Students with less severe refractive disorders showed a stronger increase in clinical refraction after exercise than students with moderate to high degrees of myopia. Conclusion. We concluded that the load reduces the absolute volum of accommodation, and this, in turn, leads to an increase in clinical refraction, dilated pupil and reduced visual acuity. Students with emmetropia and mild myopia are particularly susceptible to the above-mentioned changes.
