  • Retinal edema and hard exudates are caused by the breakdown of the blood-retina barrier, allowing leakage of serum proteins, lipids, and protein from the vessels. (medscape.com)
  • Serum lipids aggregate as exudates, and a build-up of serous fluid causes retinal edema. (aarogya.com)
  • The Early Treatment Diabetic Retinopathy Study (ETDRS) coined the term "clinically significant macular edema" (CSME) to describe when edema or hard exudates were likely to threaten the most visually important part of the central retina, called the fovea. (seeclearnj.com)
