Abstract:
AIM: To investigate the value of ultrasonography in diabetic retinopathy ( DR) .?METHODS: Totally 103 cases ( 103 eyes ) of type 2 diabetes mellitus were selected from May 2015 to May 2017 in our hospital, there were 32 patients 32 eyes with non diabetic retinopathy ( NDR) , 40 patients 40 eyes with non proliferative diabetic retinopathy ( NPDR ) , and 31 patients 31 eyes with proliferative diabetic retinopathy (PDR), 40 healthy volunteers (40 eyes) were selected as control group, the maximum systolic blood flow velocity ( PSV ) , end diastolic velocity ( EDV ) and resistance index (RI) of the central retinal artery (CRA), posterior ciliary artery ( PCA ) and ophthalmic artery ( OA ) were detected by color Doppler ultrasound.?RESULTS:The difference of PSV, EDV and RI of CRA, PCA and OA in each group was statistically significant (P<0. 05). The PSV of CRA, PCA and OA in NDR group were 12. 38 ± 2. 10cm/s, 13. 36 ± 2. 55cm/s and 32. 04 ± 6. 07cm/s, significantly higher than that of NPDR group (9.70±1.67cm/s, 12.20±2.01cm/s and 27.40±4.32cm/s) and PDR group ( 7. 13 ± 1. 40cm/s, 10. 31 ± 1. 82cm/s and 22.10±3.51cm/s) (P<0. 05). EDV were 4. 67±1. 20cm/s, 5. 61 ± 1. 25cm/s and 8. 40 ± 1. 51cm/s, significantly higher than that of NPDR group (3. 52±1. 19cm/s, 5. 01±1. 30cm/s and 6.61±1. 67cm/s) and PDR group (2. 48±1. 02cm/s, 4. 11±1.04cm/s and 4. 01±1. 52cm/s) (P<0. 05). And RI were 0. 63 ± 0. 07, 0. 60 ± 0. 04 and 0. 77 ± 0. 05, was significantly lower than that of NPDR group (0. 72±0. 06, 0. 67±0. 05 and 0. 81 ± 0. 03) and PDR group (0. 80 ± 0. 09, 0. 74±0. 06 and 0. 86±0. 04) (P<0. 05).?CONCLUSION: Color Doppler ultrasound monitoring the hemodynamic changes of ocular blood vessels in diabetes can provide evidence for early detection of diabetic retinopathy.
