What tests are used to diagnose retinal diseases?
Common tests include a dilated retinal examination and optical coherence tomography (OCT). Depending on the condition, we may also use ultra-widefield retinal imaging, ocular ultrasound, or fluorescein angiography. The tests needed vary according to the suspected retinal disease and how clearly we can view the inside of the eye.
