A total of 3 studies (411 patients) were enrolled in the meta-analysis. Central retinal arteriolar equivalent found to be not different between patients with and without dipping status (mean differences [MD]: -0.01; 95% CI: -0.23 to 0.20; I²=0%; P < 0.610). Regarding central retinal venular equivalent, dippers showed significantly lower values compared to non-dippers (MD: -0.25; 95% CI: -0.47 to -0.03; I²=0%; P < 0.024). For the comparison between nighttime and daytime BP regarding the damage in small retinal vessels, we identified only 5 studies.

In summary, this is the first effort to summarize evidence on the effects of day-to-night variation of BP on the retinal small vessels. According to the findings of the present systematic review and meta-analysis, non-dipping status may be associated with retinal venular dilatation, and elevated nighttime BP with retinal arteriolar narrowing.
