ABSTRACT We obtained audiograms and auditory brainstem responses from 44 patients with Duane's retraction syndrome to assess the incidence and nature of hearing deficit. Of 44 patients, seven (15.9%) had evidence of hearing impairment. Three (6.8%) subjects had a temporary conductive hearing loss because of middle ear fluid, and another patient had hearing loss from Crouzon's disease. The remaining three (6.8%) patients demonstrated sensorineural hearing deficit. This hearing impairment was attributed to a cochlear lesion and not to a pontine lesion. We believe that the frequency of sensorineural hearing loss in these patients warrants hearing screening programs similar to those used for infants in neonatal intensive care units.

    ABSTRACT: Although the high incidence of skeletal, neural, and other ocular problems has been identified in previous reports of large cohorts of patients with Duane syndrome, there has not been any documentation of anomalies in close relatives. Patients with Duane syndrome have a greater than 50% incidence of associated abnormalities that include deafness, other ocular anomalies, cranial nerve palsies, and skeletal abnormalities. This study was undertaken to review the experience of our strabismus service with patients who have Duane retraction syndrome (DRS) and to delineate the associated anomalies in them and their first-degree relatives. A prospective study of all patients with Duane syndrome who were seen at the strabismus service at Moorfields Eye Hospital has been ongoing for the last 4 years. All patients were assessed for the presence of ophthalmologic features of DRS and then referred to the pediatric service for a physical and neurologic examination. First-degree relatives were also examined, and a family pedigree was generated. We have evaluated 68 patients with DRS, of which 60.2% were female patients. The left eye was involved at a ratio of 4:1 in unilateral cases. The number of bilateral cases was 57.3%. Among the patients with DRS, 46% had first-degree relatives with associated abnormalities. The high incidence of associated anomalies in patients and first-degree relatives may suggest that a common genetic defect is responsible. This has to be confirmed with molecular genetic studies, which were not performed on these families because of a lack of available resources. However, our findings may indicate that the inheritance of Duane syndrome is much higher than the 10% previously reported, if any congenital abnormality is accepted as DRS associated. Children with Duane syndrome may benefit from a full medical assessment, in view of the frequency of other abnormalities, and so may their siblings.

    ABSTRACT: To describe the clinical characteristics of bilateral Duane syndrome. Retrospective medical record review (1982 to 2003) for patients with a diagnosis of Duane syndrome (examined by a pediatric ophthalmologist) who were bilaterally affected and had no prior ocular surgery. Data collected included type of Duane syndrome, gender, family history for strabismus, abnormal head position, versions, strabismus measurements, associated ocular and/or nonocular abnormalities, and amblyopia status. Of 270 patients with the diagnosis of Duane syndrome, 37 (14%) were bilaterally affected. None had ocular surgery prior to referral. Twenty-two (59%) were male, 35 (95%) had the same Duane syndrome type in both eyes, 29 (78%) had strabismus in primary position, 9 (24%) had ocular and nonocular congenital abnormalities, 6 (16%) had amblyopia, and 8 (22%) had a recorded strabismus family history. Unlike unilateral Duane syndrome, bilateral Duane syndrome may be more common in males and associated with a higher prevalence of strabismus in primary gaze position. The prevalences of amblyopia, positive strabismus family history, and associated congenital abnormalities in this series of bilateral cases is similar to the reported prevalence.

    ABSTRACT: We present the case of a 17-month-old male patient with a bilateral Duane syndrome type 1 associated to unilateral cochleovestibular dysplasia, perilymphatic fistula and recurrent meningitis. Diagnosis was carried out by MRI and CT scan. His management and treatment are described, as well as the postoperative evolution. We believe this is an exceptional case due to the low frequency of this syndrome, as well as to the otoneurological complications.
