Purpose:
The aim of the study is to investigate corneal sensitivity and the risk factors of corneal hypoesthaesia in diabetics.
Methods:
General examination and full ophthalmologic examination completed by exploration of corneal sensitivity were performed in one hundred thirty diabetic patients.
Results:
Eleven per cent of patients showed microkystic oedema, whereas corneal hypoesthaesia was found in 45% of cases. Corneal hypoesthaesia was correlated with the duration and balance of diabetic mellitus, the age of patients and the presence of diabetic retinopathy. On the other hand, peripheral neuropathy was found in 88% of cases.
Conclusion:
Ophthalmologic examination of diabetics should not be limited to retina only but should also include the entire eye ball and especially the cornea in patients with high risk.
