Objective: Carotid artery pathologies may have a part in the etiology of the patients with a normal tension glaucoma. We compared cases with primary open angle glaucoma (POAG) and normal-tension glaucoma (NTG) with respect to carotid artery pathology.
Materials and Methods: Carotid arteries of 58 patients (23 POAG and 35 NTG) were assessed using color doppler USG (Toshiba SSA-270-A, 7.5 Mhz linear probe). The mean age was 65.87±9.61 (50-80) for POAG and 61.11±11.17 (40-81) for NTG. Vessel wall thickness, plaque formation and the degree of stenosis in main carotid and internal carotid arteries were recorded asuming 50% and over as pathologic.
Results: There was no difference between POAG and NTG regarding age. As far as the frequency of carotid artery pathologies are concerned, there was stenosis exceeding 50% in one patient with POAG as well as intimal thickness and plaque formation in eleven. In NTG, stenosis exceeding 50% in 6 patients as well as intimal thickness and plaque formation in eight patients were found. No statistically significant difference was noted between the groups in terms of the presence of carotid artery pathology. When patients were divided into two groups below 59 and over 60 years of age independent of the type of glaucoma, there were age related increase with regard to intimal thickness, plaque formation and stenosis.
Conclusion: In this study, it appeared that carotid artery pathology had similar risk factor for POAG and NTG. There was an increase in carotid artery pathology with increasing age and this was independent from the type of glaucoma.Keywords: Normal tension glaucoma, Primary open angle glaucoma, Carotid dopplerT Klin Oftalmoloji 2004, 13:26-30
