- Cataracts and Vitamin D - many studies 12 as of April 2023
- Cataracts prevented and perhaps treated by Vitamin D - 2015
- Cataracts associated with low Omega-3, Vitamin D, etc – April 2017
Vision category starts with the following
- 12% larger pupils in children who are Vitamin D deficient – Feb 2024 parasympathetic nervous system?
- Myopia, AMD, Dry Eye, and Diabetic Retinopathy are all associated with low Vitamin D - April 2023
- An ocular disease can be associated with low vitamin D and 1 of 5 poor vitamin D genes – June 2022
- Eye vitamin D may not be associated with blood VitD, but is associated with CYP27B1 and CYP24A1 – Nov 2019
- Vitamin D treats and prevents a variety of eye problems (need 70 ng) – June 2018
- Vitamin D and Myopia, AMD, Diabetic Retinopathy, Uveitis, Glaucoma, VDR etc. – May 2015
- Tears often have 25 % higher levels of vitamin D than does blood

Purpose. To study the relation between the serum 25-hydroxyl vitamin D (OH D) level and the occurrence of age-related cataract in a case-control study.
Patients and Methods. 325 cataract patients and 385 control individuals of both sexes were examined for the 25-OH D level using the chemiluminescent microparticle immunoassay (CMIA) technology.
Results. Mean 25-OH D level in cataract patients was 7.6 ± 5.5 ± 11.2 ng/mL and median was 5.6 (2.6–31.9), while in the control group, mean 25-OH D level was 18.5 ± 9.6 ng/mL and median was 17.8 (3.4–37.8) ( value < 0.001). There was a statistically significant difference among the different types of cataracts with the lowest level in nuclear cataract.
Conclusion. 25-OH D levels in all enrolled individuals were below the reference levels with a severe deficiency in cataract patients. These results might highlight the role of deficiency of 25-OH D in age-related cataract patients.
