Age-related macular degeneration is one of the greatest challenges in ophthalmology today. We know that there are two types: the dry form and the wet form. The dry form is experienced by patients who are slowly losing their vision. It has been demonstrated that treatment with antioxidants and vitamins can reduce vision loss, although the slowing down of the process is not particularly spectacular. The wet form, which is so called because fluid is produced in the macula, is the most destructive, and current treatment involves the combining of photodynamic therapy, which started to be used some years ago, with other treatments, which has produced more positive results. Each year, new possibilities appear, which help in the fight against this disease.
Are there any safety considerations when performing an angiography?
The most important is to ensure that the patient is not allergic to the substances to be injected.
If a patient with age-related macular degeneration (AMD) sees wavy lines, should it be treated as an emergency?
Yes, it is an emergency, but relatively speaking, as it is possible to wait 3 or 4 days. It is necessary to examine the eye, because the symptom could indicate the onset of decompensation, which can cause severe loss of vision. This distortion is sometimes not due to decompensation, but it always needs to be confirmed.
Is it counterproductive for the patient to have an angiography when undergoing eye treatment?
It is not counterproductive for any eye treatment
What is angiography?
It is a diagnostic technique to determine pathological and abnormal structures in the blood vessels and the different layers of the retina. It can be used in cases of macular degeneration, diabetic retinopathy, vasculopathy and many other macular disorders.
What is the Amsler grid?
It is a grid of straight horizontal and vertical lines with a central point, used as a tool to detect visual disturbances in patients with scotoma or other anomalies.
Why is angiography useful?
Angiography is a technique used to delineate retinal or choroidal cases. Different contrasts are used, usually sodium fluorescein or indocyanine green. The scan is also useful for the diagnosis of other retinal diseases, such as pigment epithelium. In general, angiography is used to study many retinal diseases and their diagnosis.
