Study of hearing in children with visual deficiency

PURPOSE: analyze the hearing of students presenting with visual deficiency (low vision and blindness). METHOD: evaluation of 30 (100%) children, divided into two groups: Group I comprised 15 (50%) children with visual deficiency; and Group II comprised 15 (50%) children with normal vision, without hearing and/or education complaints. The patients underwent meatoscopy, liminal tonal audiometry, logoaudiometry and immitanciometry; in addition to sound location tests in five directions, verbal and non-verbal sequential memory, speech-in-noise tests, dichotic digit tests, duration standard behavior and random gap detection test (RGDT). RESULTS: concerning the basic auditory evaluation in Group I, four (26.6%) students showed results altered - two (13, 3%) with conductive hearing loss, one (6, 8%) with mixed and one (6, 8%) with neurosensorial hearing loss. Conversely, all participants in Group II showed normal results. In the sequence of auditory processing tests, 10 (66.6%) students in Group I showed results altered and four (26.6%) showed normal results. CONCLUSION: Group I demonstrated unfavorable performance in comparison with Group II, either in the basic auditory evaluation or in the sequence of auditory processing tests.
