There are 3 possible tests you will be required to do.
The main test is optical coherence tomography (OCT). This test uses light to take cross-sections of the retina, giving an insight into the retinal layers in great detail. It diagnoses retinal disease at an earlier stage and determines how patients may respond to treatment, including injections into the eye. It is also used to determine how many injections are needed and how often they are required.
Scanning laser ophthalmoscopy (SLO) is a broad field colour photography of your retina, including autofluorescence of your macula and choroid.
The third test used is angiography. At Clinica London, these tests are performed by injecting a fluorescent dye into a vein in the back of the hand, which circulates through the body to the blood vessels in the retina. This allows the medical retinal consultants to visualise and document the blood supply in the retina and check for any leakage from the blood vessels. The specialist retinal Consultant can then direct treatment to the areas of leakage if necessary, using low threshold laser.
