Ophthalmologic disorders in children with syndromic and nonsyndromic hearing loss

Arch Otolaryngol Head Neck Surg. 2010 Mar;136(3):277-80. doi: 10.1001/archoto.2010.13.

Abstract

Objective: To determine the rate of ophthalmologic anomalies among patients with syndromic and nonsyndromic, congenital sensorineural hearing loss (SNHL) to assess the need for comprehensive ophthalmologic evaluation in these children.

Design: Retrospective medical chart review of children with SNHL who underwent comprehensive evaluation by pediatric ophthalmologists and geneticists.

Setting: Tertiary care pediatric hospital.

Patients: Seventy-seven patients with SNHL.

Main outcome measures: Degree of hearing loss (HL) and presence of ophthalmologic and genetic disorders.

Results: The overall rate of ophthalmologic disorders was 32% (25 of 77 patients). When children with multisystem genetic disorders known to be related to visual loss were excluded, the rate fell to 23% (12 of 53 vs 13 of 24; P = .006). There was no statistically significant difference in the degree of HL between patients with and without eye disorders (mean [SD], 46.5 [29.9] vs 49.1 [32.3] dB HL; P = .75). Patients with eye disorders were significantly more likely to have a multisystem genetic disorder (13 of 25 [52%] vs 11 of 52 [21%]; P = .006). No patients with ocular abnormalities had isolated otologic disorders, but 9 of 52 (17%) of those patients without ocular abnormalities did.

Conclusions: Comprehensive ophthalmologic examination revealed a rate of ophthalmologic disorders in children with SNHL in the lower end of the previously reported rates of 31% to 61%. Children with nonsyndromic SNHL have an approximately 2- to 3-fold increase in ocular abnormalities compared with the general pediatric population. Ophthalmologic and genetic consultations are warranted in patients with congenital SNHL.
