Abstract

AIM OF THE STUDY: 1. To evaluate incidence of sensorineural hearing loss & retinopathy in patients with diabetes mellitus. 2. To correlate association of sensorineural hearing loss with retinopathy in patients with diabetes mellitus. METHOD AND MATERIAL: A sample of 92 subjects are selected by blind randomization & divided into cases & controls of 46 individuals in each. Detailed clinical examination of ear & eye is performed, including tunning fork tests fundoscopy & subjected to investigations. The data collected from these tests & investigations are subjected to appropriate statistical tests to arrive suitable conclusions. RESULT: In our study 73.9% of cases had diabetic retinopathy and 89% of cases had sensory neural hearing loss with significant P value. 60.8% cases with >2years of DM had retinopathy. About 39.1% cases of retinopathy had DM for >4 years. 4 out of 5 cases of PDR had DM > 6 years. 65.2% of cases with SNHL had DM > 2years of which 41.3% cases with SNHL had DM >4 years. Cases with HbA1C >7, 71.7% of them had retinopathy of which 43.47% of them had HbA1C >8. Similarly 84.7% of cases having SNHL had HbA1C >7 of which 41.35% had HbA1C >8. 47.8% of cases having SNHL >41dB (>/=moderate SNHL) had retinopathy of grade 2 NPDR or higher severity of retinopathy. It is highly significant that diabetics with greater SNHL have more severe retinopathy with P value: - <0.01. CONCLUSION: A statistically significant correlation was found between SNHL and the severity of diabetic retinopathy. More severe grades of SNHL and retinopathy manifesting in patients with higher levels of HbA1C and prolonged duration of DM.
