Objective: To investigate the correlation between corneal thickness and colour Doppler sonography of retrobulbar vessels of glaucoma patients.
Methods: Corneal pachymetry as well as colour Doppler sonography of the retrobulbar vessels (ophthalmic artery, central retinal artery and cilliary arteries) was performed on 57 glaucoma patients. Pearson’s correlation was used to evaluate the association between corneal thickness and retrobulbar blood flow.
Results: No significant correlation was found between corneal thickness and retrobulbar blood flow. R² ranged between 0.00003 and 0.04.
Conclusions: In our patients no correlation was found between corneal thickness and the basal blood flow in the retrobulbar vessels. Maximum systolic, diastolic velocity, and resistivity index were all not associated with corneal thickness.
