Visual and hearing problems have a direct impact not only on the development and learning, but also psychological and social aspects. Hence the importance of early detection and correction. Specialists in Pediatrics advise parents to perform diagnostic tests outlined below to ensure good visual and auditory health of their children.
Early detection, both hearing and visual, can solve the problem some cases and in others, at least correct the degree of hearing or vision of the patient. In any case, as soon as possible vision and hearing problems are detected, the better the prognosis of the disease. In addition, the sooner the correction of these deficits is performed before improves learning, psychomotor development and social relations of children.
Diagnosis of deafness in the early years of life
During the immediate neonatal period, ie during the first days of life, Evoked Potentials Auditory performed to detect congenital deafness. This diagnostic test studies the nervous system reaction to auditory stimuli.
From three or four years of life periodic hearing tests are performed to detect late-onset congenital deafness and, above all, acquired deafness. In addition, all well-child reviews the ear canal and the eardrum is explored by otoscopy to detect infections and other ear pathologies.
Early detection of vision defects
The detection of visual problems begins from the moment of birth through periodic examination of the anatomy of the eye and eye reflexes. These evaluations can detect congenital anomalies, tumors and ocular motility disorders.
At 12 months of life exploration is done by Autorefraction. The objective of this test is to detect asymmetries in vision and refractive measure to assess the need for spectacle correction. This test is periodically repeated every year.
Later, toward the three or four years the test of visual acuity, binocular vision tests and viewing the colors are added. All the complete screening also is repeated annually.
This schedule diagnostic tests may change if a hearing problem or vision is suspected at some point. If necessary, the pediatrician will refer the child to an ophthalmologist or otolaryngologist.
