OBJECTIVES: To review the ocular abnormalities in children treated with cochlear implant. MATERIALS and METHODS: A total of 51 children (29 boys, 22 girls) who were under 18 years old, presented previously with severe to profound hearing loss, and underwent cochlear implantation surgery were included in this study prospectively. A detailed ophthalmic examination, including refraction, best corrected visual acuity, ocular motility, slit-lamp biomicroscopy, and dilated fundus examination, was performed for each patient. RESULTS: Mean age of the patients was 80.10±38.64 (range, 18-168) months. A total of 13 (25.4%) children had at least 1 ophthalmic abnormality. The majority of the detected ophthalmic abnormalities were hyperopia and astigmatism (6 patients had hyperopia, 5 had astigmatism, and 2 had hyperopia plus astigmatism). Strabismus (esotropia) was found in 2 patients, 2 patients had refractive amblyopia, and 2 patients had nystagmus. Moreover, 3 patients had microcornea, 2 patients had cataract, and 1 patient had epiblepharon. Optic disc coloboma (3 patients), choroidal coloboma (1 patient), and pigmentary abnormality (1 patient) were noticed on fundus examination. Congenital rubella syndrome (2 patients), Waardenburg’s syndrome (1 patient), and CHARGE syndrome (coloboma, heart defects, choanal atresia, growth retardation, genital abnormalities, ear abnormalities) (1 patient) were also present. CONCLUSION: Children treated with cochlear implant should be consulted with an ophthalmologist to identify any treatable ocular abnormality.
