What is typically observed during a fundoscopy for central retinal vein occlusion?

During a fundoscopy for central retinal vein occlusion, one of the hallmark findings is the presence of severe retinal hemorrhages. These hemorrhages occur due to the impaired venous drainage caused by the occluded central vein, leading to increased pressure within the retinal capillaries. This increase in pressure results in the rupture of these vessels, causing bleeding within the retina.

In addition to severe retinal hemorrhages, other associated findings may include cotton wool spots, which indicate areas of ischemia, and venous dilation. The identification of these retinal changes is crucial as it aids in the diagnosis and management of the condition. The presence of serious retinal hemorrhages strongly suggests a significant disturbance in the vascular structure of the retina, making it an important sign to observe during the examination.
