[Importance of studying the accommodation function in the diagnosis of clinical forms of hypermetropia].

Two hundred and thirty-one patients, aged 6 to 18, with hypermetropia were examined. They were shared between two groups with respect to an accommodation state: group 1--patients with weak accommodation, group 2--patients with normal accommodation. The below ocular parameters were registered for groups 1 and 2, respectively: axial size--22.35 mm and 21.58 mm, corneal diameter--11.48 mm and 10.74 mm, scleral ring diameter in the projection of the scleral central portion--14.66 mm and 13.98 mm, ocular refracting power--59.79 d and 62.23 d, corneal refraction--41.85 d and 42.82 d, and lens refraction--22.05 d and 24.03 d. New clinical signs were specified for uncomplicated type of congenital hypermetropia. The parameters of patients with normal-accommodation hypermetropia are typical of axial hypermetropia in adults due to growth inhibition, while the parameters of patients with weakened accommodation are typical of optical hypermetropia as a variation of normal eye development.
