Accommodative asthenopia in schoolchildren with mild and moderate ametropia

The authors followed up 40 schoolchildren with accommodative asthenopia at the age from 8 to 17. The patients were divided into 2 groups according to the refraction type: with mild and moderate myopia (mean -1.93+0.18 D) and with mild and moderate hyperopia (mean +2.08+0.28 D). Weakness of accommodation in the nearest zone of clear vision and persistent strain of accommodation (mean 1.0 D) in the further zone of clear vision was noted in schoolchildren both with myopic and hyperopic refraction due to the overstrain of visual system. In accommodative asthenopia nonsynchronous strain of both eyes accommodation was present being expressed in anisometropic accommodation in myopia in the nearest zone of clear vision (mean 1.52+0.19 D), and in hyperopia both in the nearest and in further zone of clear vision (mean 2.43+1.16 D).
Normalization of indices of absolute accommodation in patients with myopia and hyperopia leads to the improvement of the vision at far and at near and to asthenopia elimination in 95% of cases.
