| Summary: |
Purpose: Color Doppler
assessment of blood flow in ocular circulation in type 2
diabetes patients.
Material and methods: Total of 56 patients were
included in the study and divided into 3 groups: group I
– control group, group II – type 2 diabetes patients
without diabetic retinopathy, group III – type 2
diabetes patients with nonproliferative diabetic
retinopathy. USG Color Doppler method was used in all
patients to assess peak systolic blood velocity (PSV),
end-diastolic blood velocity (ESV) and resistivity index
(RI) in the following arteries: ophthalmic artery (OA),
central retinal artery (CRA), short posterior ciliary
artery (SPCA). In addition several clinical parameters
including age, diabetes duration, blood pressure, body
mass index (BMI) and blood glucose level with empty
stomach were statistically analyzed.
Results: Peak systolic blood velocity (PSV) and
end-diastolic blood velocity (ESV) in ophthalmic artery
(OA) in diabetic patients were significantly lower in
comparison to the control group. Peak systolic blood
velocity (PSV) and end-diastolic blood velocity (ESV) in
central retinal artery (CRA) were significantly lower
only in patients with diabetic retinopathy. In short
posterior ciliary arteries (SPCA) only peak systolic
blood velocity (PSV) was decreased in patients with
diabetic retinopathy. Average age of patients was
significantly higher in the group with diabetic
retinopathy. Diabetes duration was significantly longer
in group III in comparison to group II.
Conclusions: Color Doppler imaging method is
useful for assessing blood flow in ocular circulation.
Blood flow in ophthalmic artery is decreased in patients
with diabetes. Reduction of blood flow in central
retinal artery and short posterior ciliary arteries can
be significant in the development of diabetic
retinopathy. |
