Vitamin D Deficiency in Patients with Central Retinal Vein Occlusion: A Case Control Study.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as a randomized controlled trial.

The researchers aimed to evaluate if patients with CRVO have more vitamin D deficiency compared to matched controls.

Who Took Part

According to the abstract, 72 patients were involved.

By PubMed's age tags, the people studied were older adults, both men and women.

Prospective match controlled study of 72 patients with CRVO and 144 matched controls.

How the Study Was Run

The researchers set it up as a randomized study.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

All new CRVO cases presenting at St.

Erik Eye Hospital, Stockholm, Sweden during the study period were approached to participate.

Statistics Sweden provided randomly selected controls matched for age, gender, and season.

The first 18 cases of CRVO and 36 controls for each of the four seasons were included and blood was drawn for 25-OH vitamin D analysis (25(OH)D).

What Was Measured

The subject headings attached to it are Case-Control Studies, Incidence, Odds Ratio, Retinal Vein Occlusion, Risk Assessment, Risk Factors and Seasons.

The authors tagged it with the keywords Prospective studies, seasonality and vitamin D deficiency.
