Purpose: In order to verify the prevalence of ocular abnormalities in patients who are deaf due to genetic causes, this paper presents the visual assessment of 97 deaf patients. Methods: 97 patients with definite or suspected diagno- sis of congenital and genetic deafness underwent a complete ophthalmologic evaluation; 10 patients were excluded. Results: 42 (48.28%) patients presented one or more ocular abnormalities, 22 (25.29%) patients presented several abnormalities and clinical manifestations of established genetic diseases. Conclusions: The ocular abnormalities may be the only clinical manifestations associated with deafness. Therefore the ophthalmological examination is a helpful tool for the etiological diagnosis of deafness.
