Yet another reason to go outside.
A new study investigated whether there was a connection between serum 25-hydroxy vitamin D, vitamin B12, and folic acid levels in patients with progressive and nonprogressive keratoconus. The key question they were looking to answer was: Does the insufficiency of vitamin D play a crucial role in the etiopathogenesis of keratoconus?
Tell me about the study.
The study included 55 patients with keratoconus (roughly half were progressive and half nonprogressive) and 30 controls. Serum 25-hydroxy vitamin D, B12, and folic acid levels were measured and compared between the control group and the keratoconus groups.
What did they find?
Serum vitamin D levels were significantly reduced in the keratoconus group as compared to the control group. There was a small difference in vitamin D levels between the progressive and nonprogressive keratoconus groups, but this was not statistically significant. There was no difference in the B12 and folic acid levels between the three groups.
The take home:
Vitamin D supplementation can be promising for vitamin-deficient patients in preventing the development of keratoconus. However, randomized controlled prospective studies investigating the topographic changes in patients with keratoconus after vitamin supplementation are necessary to suggest a regimen.
