The eye doctor performs the following test to diagnose the condition:
Dilated fundus examination
Optical coherence tomography (OCT)
Fundus fluorescence angiography (FFA)Dilated fundus examination:
The eye doctor examines the retina after instilling dilating eye drops. These drops are put at intervals of every 15mins for 3 to 4 times to dilate the pupil, i.e. the colored diaphragm of the eye. The retina is then examined with a high powered convex lens on the slit lamp, to visualize the macula in detail.OCT:
It is an instrument which gives high quality, high resolution three dimensional view of the macula in cross section helping the eye doctor to know the exact pathology which can help appropriate treatment.FFA:
It is a test done to visualize and photograph the retina after the injection of a specialized fluorescent dye into the patient’s vein. It helps to visualize the retinal blood vessels and interpret whether its functioning is normal.
