[The visual manual localisation in oblique plane among healthy persons]

The investigation of the visual manual localisation in horizontal plane was led among healthy people to study its behaviour. In medical literature is lack of assessment of visual manual localisation in oblique plane. The aim of the work was to estimate the visual manual localisation in the action of the vertical rectus and oblique muscles in healthy persons.

I studied healthy people with no strabismus, who were divided into three groups. The first group consisted of children aged 6-7 years (111 persons), the second group was aged 14-15 years (111 persons) and the third group consisted of adults aged from 22-26 years (111 persons). The patients were examined by an ophthalmologist to check for eye acuity. The investigation of localisation was done on the special reconstructed vertical manual localisator.

From results of study localisation in oblique plane were observed three patterns of localisation; the first--exact localisation, the second--ancrossed localisation and the third--crossed localisation. The most often were represented precise localisation in three study groups. The visual manual localisation in oblique plane changes together with age of patient.
