In this article, we will explore a video presenting the imaging of retinal vessels after contrast injection. The procedure was carried out during a routine examination of a patient at one of the Oculus Eye Clinics. The video reveals an obstructed vessel, disrupting blood flow and creating a darker area around the retina. This obstruction resembles a similar condition seen in the brain, requiring prompt medical attention.
Imaging retinal vessels with a contrast medium
The procedure involves capturing images of retinal blood vessels using a specialized imaging technique called retinal angiography. During this procedure, a contrast agent is injected into the patient’s bloodstream. The contrast agent circulates in the eye’s blood vessels, enabling them to be seen during imaging.
VIDEO: Observation of an obstructed vessel
Around the 20th second of the video, an obstructed vessel becomes clearly visible. The contrast medium, represented by a white substance, cannot pass through the blocked vessel. This indicates that blood flow is impeded at this point, resulting in insufficient supply to the surrounding retinal tissue.
Identifying the affected retinal area
The area surrounding the blocked vessel appears darker, indicating reduced blood supply and nutrient deprivation in this part of the retina. This phenomenon is known as non-perfusion and can lead to significant visual impairment if not promptly treated. Non-perfused areas are of particular concern, as they can lead to loss of retinal function and potential vision deterioration.
Medical care
The management of retinal vessel occlusions requires a similar approach to that of brain vessel occlusions. Prompt medical intervention is essential to prevent further damage and restore blood circulation. Treatment options may include medication, laser eye therapy or, in more severe cases, surgery. Early detection and intervention can significantly improve the prognosis of patients with this type of condition.
Imaging retinal vessels with contrast media offers invaluable insights into the health of the retina and the condition of its blood vessels. Just as vessel blockages in the brain can have serious consequences, prompt treatment of retinal vessel occlusions is crucial to preventing vision loss. If you notice any sudden changes in your vision, or if you have any concerns about your eye health, it’s essential to consult an eye care professional. Regular eye examinations are also recommended starting at the age of 55.
