To our best knowledge, this is the first case-control study with a large number of participants to evaluate ocular blood flow in patients with cataracts.Materials and methods: Color Doppler and duplex sonography of the orbital vessels was performed in 224 eyes of 112 patients with known bilateral age-related cataracts and in 76 eyes of 38 healthy age- and sex-matched volunteers.Results: The mean &plusmn; (standard deviation [SD]) of peak systolic velocity (PSV) of the ophthalmic artery in patients with cataracts (34.59 &plusmn; 22.49 cm/second) was significantly different to that in controls (52.11 &plusmn; 14.01 cm/second) (P &lt; 0.001). The mean &plusmn; SD PSV of the central retinal artery in patients with cataracts (15.31 &plusmn; 4.93 cm/second) was significantly different to that in controls (9.61 &plusmn; 5.64 cm/second) (P &lt; 0.001).Conclusion: The mean PSV and resistive index (RI) of the ophthalmic and central retinal arteries were lower in cataract patients when compared with normal subjects. This suggests that ocular hypoperfusion and changes in ocular hemodynamic may have a role in the formation of age-related cataracts.Keywords: retrobulbar blood flow, age-related, cataract, color Doppler ultrasonographicMohammadi AKhorasani NMoloudi FGhasemi-rad MDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2011, Iss default, Pp 1521-1524 (2011)
