Evaluation of the ocular blood flow status using color ultrasound dopplerography in patients with glaucoma followed combined treatment
Purpose : to study the indices of the eye ball vessels hemodynamics before and after non-penetrating deep sclerectomy (NPDS) combined with vasoreconstructive surgery (VRS) in patients with glaucoma. Material and methods : 29 patients (36 eyes) with POAG of the II and III degree were examined. The age was from 54 to 72 years old, 10 male, 19 female. Results : it was noted that the following NPDS the increase in maximum systolic and minimum diastolic blood flow speed in all examined vessels by 25 % and the decrease in the resistant index by 5 % occurred. In combined treatment the increase in blood flow in all examined vessels, especially in ocular artery, central retinal artery and short posterior ciliary artery up to 40 % and more, the decrease of index by 8-10 % of the eye was observed. Also we noted the significant improvement of the ocular functional indices. Conclusion : the method of ultrasound color dopplerography allows assessing accurately enough the blood flow status in the vessels that feed the eyeball. Following NPDS we note the improvement of the blood flow in all examined vessels, and in combination with VRS the most positive effect is observed.
