**19. Retinal vascular diseases and cholesterol**

Hyperlipidemia is associated with retinal vascular diseases. In old age, structures called "druzen" in tissue are similar to atherosclerotic lesions. Ischemic optic neuropathy can be seen as a result of stenosis in the retinal arteries and venules. In the ACCORD Eye trial, although strict treatment for diabetes and hyperlipidemia was beneficial, there was no significant benefit from strict blood pressure regulation [37, 38].
