Ocular motility in children between ages 7 and 15

Human growth and development is constantly exposed to physical, mental and social changes that make it necessary to observe and analyze measurable variables of proper growth at early ages that could allow us to prevent health problems in adulthood. For the purposes of this document, our approach focuses on vision problems that develop more strongly for not receiving prompt and adequate treatment. Health problems commonly identified in children are associated with strabismus, amblyopia [1], [2], Apert syndrome, cerebral palsy, retinoblastoma, nystagmus, among others [3], [4], [5] as well as rehabilitation processes for loss of the principal organ of vision, the eye. Loss of this organ may be due to congenital causes, such as anophthalmia and microphthalmia or acquired causes as in the cases of trauma, diseases like retinoblastoma, glaucoma, cancer and surgical complications. To this day there have not been any reported benchmarks for clinical comparisons of lateral and vertical eye movements in patients with and without associated pathologies [4]. In order to build a reference for clinical comparisons, an eye movement quantification tool called MODET® [6] is used. This tool allows to obtain a reliable measure of eye movements made by a subject in the primary and secondary diagnostic positions of gaze according to the direct confrontation eye test generally used by ophthalmology specialists. This paper presents results of the measurement of ocular motility on 26 children in southwestern Colombia between the ages of 7 and 15 years; these patients did not have associated pathologies, finding motion ranges for each one of the defined diagnostic positions. Also, a pathological case of anophtalmia [6] is presented as first comparison example of eye movement ranges in pathological and non-pathological cases.
