[Ciliary circulation in glaucoma complicated by diabetes mellitus]

The speed of blood perfusion and the pulsation curve in ciliary arteries was checked by the method of Doppler's pulsating focused ultrasonography in 30 patients aged 46-78 years treated for glaucoma and diabetes. The data obtained were compared with analogical data in nondiabetic patients with glaucoma. It was established that the increase of the intraocular pressure caused a larger and earlier impairment of the regulating mechanism of the ciliary microcirculation in diabetic patients with glaucoma in comparison with the group of glaucomatous patients without diabetes. Particularly high values of pulsation indexes for ciliary arteries were observed in eyes with glaucoma and with diabetic changes rated as the fifth group of diabetic changes.
