Classification and Symptoms

• Retinal Artery Occlusion

  Retinal artery occlusion can be classified into central retinal artery occlusion and branch retinal artery occlusion based on the location of the vascular occlusion. The causes of occurrence are often unclear, but factors such as emboli or blood clots can act as triggering factors. In particular, in cases of central retinal artery occlusion, the visual prognosis is usually poor, and there is a risk of progression to systemic disease.

  • Central retinal artery occlusion resulting
    in a severe narrowing of the retinal artery, and the posterior segment of the retina appearing blurry.

  • Central retinal artery occlusion resulting
    in an occluded artery that appears as black lines with non-fluorescence.

• Retinal Vein Occlusion

  Retinal vein occlusion can be classified into central retinal vein occlusion and branch retinal vein occlusion based on the location of the vascular occlusion. Hypertension (high blood pressure), diabetes, and hyperlipidemia (high cholesterol) can lead to the occurrence of venous occlusion. It is not classified as an ophthalmic emergency, and the prognosis is generally favorable with treatment. However, due to the gradual narrowing of the veins in this condition, delayed treatment may result in visual impairment. Therefore, comprehensive systemic examinations should be conducted to address the underlying conditions and initiate appropriate treatment.

  • Branch retinal vein occlusion resulting
    in retinal vascular tortuosity and hemorrhage

  • Central retinal vein occlusion resulting
    in venodilation and oblique veins.
