Retinale vaatocclusies

Retinal artery and vein occlusions can both lead to significant vision loss. Vein occlusions are much more common, while visual acuity is usually more severely affected in artery occlusions. In addition to ophthalmological treatment, both types of occlusions require a multidisciplinary approach, in which cardiovascular risk management is important. In the event of an artery occlusion, an urgent search for the source of the embolism must be carried out. We discuss two cases. First, a 71-year-old man with a central retinal artery occlusion who presented three hours after the event and was treated successfully. Second, a 37-year-old obese man with a central retinal vein occlusion for which he has undergone long-term treatment with intravitreal anti-VEGF injections for persistent macular edema.
