This study aimed to determine the relationship between blood pressure variability indices and retinal arteriolar diameter in non-diabetic and type II diabetes participants. Digitized retinal images were analysed to quantify arteriolar diameters in 35 non-diabetic (aged 52 ± 11 years; 49% male) and 28 type II diabetes (aged 61 ± 9 years; 50% male) participants. Blood pressure variability was derived from 24-h ambulatory blood pressure. Arteriolar diameter was positively associated with daytime rate of systolic blood pressure variation (p = 0.04) among type II diabetes participants and negatively among non-diabetics (p = 0.008; interaction p = 0.001). This finding was maintained after adjusting for age, sex, body mass index and mean daytime systolic blood pressure. These findings suggest that the blood pressure variability-related mechanisms underlying retinal vascular disease may differ between people with and without type II diabetes. date: 2016-07 official_url: http://dx.doi.org/10.1177/1479164116633424 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green article_type_text: Review verified: verified_manual elements_id: 1131034 doi: 10.1177/1479164116633424 lyricists_name: Hughes, Alun lyricists_id: ADHUG42 actors_name: Hughes, Alun actors_id: ADHUG42 actors_role: owner full_text_status: public publication: Diabetes and Vascular Disease Research volume: 13 number: 4 pagerange: 299-302 issn: 1752-8984 citation: Veloudi, P; Blizzard, L; Srikanth, VK; McCartney, P; Lukoshkova, EV; Hughes, AD; Head, GA; Veloudi, P; Blizzard, L; Srikanth, VK; McCartney, P; Lukoshkova, EV; Hughes, AD; Head, GA; Sharman, JE; - view fewer <#> (2016) Associations of blood pressure variability and retinal arteriolar diameter in participants with type 2 diabetes.
