The main objective of this study is to evaluate the efficacy at 6 months of omega 3 supplementation on macular capillary density measured in optical coherence tomography angiography in patients with minimal or moderate non proliferative diabetic retinopathy.


Diabetic retinopathy (DR) is a leading cause of vision loss worldwide and is a major public health problem.

In Western countries, the prevalence of DR is estimated to be 35% in diabetic patients, while diabetic macular edema (DME) affects 5% of them.

Currently, apart from the balance of diabetes and other cardiovascular risk factors, no specific treatment is given for the minimal and moderate non-proliferative forms.

  • DHA concentration in the retina can be modified according to the patient's diet.
  • Minimal diabetic retinopathy does not currently benefit from specific treatment outside of diabetic control.
  • Omega 3 are already known for their beneficial effects on the retina, brain and cardiovascular system but their effectiveness has not been tested on diabetic retinopathy.
  • It is therefore a question of evaluating whether an omega 3 supplementation, at a dosage of 1000mg per day, can treat a minimal or moderate stage of diabetic retinopathy.

A study by Salavila et al. has shown that the intake of LC3PUFA, via a Mediterranean diet, improved the stage of DR in diabetic patients.
