| Introduction: Visual and hearing impairment compromise the basic modes of communication leading to social isolation and impaired cognitive and general functions. Inconsistent results regarding the co-existence of eye and ear pathologies have been found. Objectives: The aim of this study is to assess audio-vestibular functions in patients with open angle glaucoma (OAG (. Patients and Methods: Fifty patients with OAG and 20 age and sex-matched healthy controls were included. Pure tone audiometry, immitencemetry, distortion product otoacoustic emission (DPOAEs), auditory brainstem response (ABR), and electronystagmography (ENG) were done and compared between the two groups. Results: Compared to the control group, patients with OAG had significantly elevated pure tone audiometric thresholds at all audiometric frequencies (P between 0.003 to 0.001), sensory neural hearing loss (SNHL) in 86% of the patients, lower amplitude of the DPOAEs at all tested frequencies, prolonged waves I, III and V in ABR and abnormal caloric test in 22% of the patients. Conclusions: The present study confirmed the association between SNHL and OAG. The results of PTA, DPOAEs and caloric tests suggesting that the cochlea is most probably the main site of pathology in patients with OAG | ||||
