[Screening for ocular involvement in deaf children]

The association between deafness and visual disorders is frequent. These disorders range from simple refractive disorder to severe disease that can lead to disability. Hence the interest of early screening. This study aims to highlight the importance of multidisciplinary management and of the need for ophthalmological examination in each deaf child. We conducted a prospective monocentric data collection from medical records of 200 children followed for hypoacousia from January 2014 to January 2015. Each child underwent complete ophthalmological examination, ENT examination and clinical examination. Data from 155 medical records were collected. Ocular involvement was found in 47 patients, reflecting a rate of 30.4%. Bilateral involvement was found in 45 patients. The main syndromic causes were: Usher syndrome (8 casess), Waardenbourg syndrome (5 cases), Alport syndrome (3 cases), Wolfram syndrome (2 cases), Goldenhar syndrome (3 cases), Cogan syndrome (3 cases), Franceschetti-Kleinsyndrome (1 case), Charge syndrome(1 case), otomandibular syndrome (1 case), Stickler syndrome(1 case), Alström syndrome (1 case), Refsum disease (1 case), Susac syndrome (1 case) and KID Syndrome (1 case). Screening for ocular involvement allowed to shorten the average length of cochlear implantation from 9 months to 3 months. There are numerous ocular and auditory involvements because of the embryological and cellular similarities of these two organs, including the retina and the inner ear. The diagnosis of these involvements is facilitated by the presence of facial dysmorphism; on the other hand, diagnosis is difficult when there are visual and auditory sensorineural involvements. Early diagnosis of ocular and auditory involvements allows for best psychomotor development and optimal social inclusion. Therefore multidisciplinary management is necessary to allow for the best psychomotor, orthophonic and visual rehabilitation.
