Retinal imaging allows us to detect and monitor slowly developing, often sight threatening conditions such as glaucoma, macular degeneration, diabetes, hypertension and high cholesterol.
A retinal camera captures a high definition digital image of your retina. This allows a very detailed assessment of the blood vessels and optic nerve located at the back of your eye. Subtle changes in the blood vessels or the appearance of your nerve or retinal tissue can be instantly and accurately assessed.
Imaging provides a detailed record of you retina and allows us to compare future images with past images to assess for change of progression of disease.
Normal Field (central) retinal imaging takes images of the central 40° of the retina. Normal Field retinal imaging therefore provides very high definition images of only a small area of the retina. Normal Field retinal imaging can also be done with autofluorescence.
Autofluorescence provides additional information, not possible with standard retinal imaging, which helps in the diagnosis, monitoring and prognosis of retinal conditions such as macular degeneration and central serous retinopathy.
Ultrawide Field Digital Retinal Imaging is the latest technology in retinal imaging and captures up to 200° of the retina in a single image. This allows analysis of both central and peripheral retinal conditions simultaneously, enabling better diagnosis and management of disease.
The Optos 200TX also allows autofluorescence imaging of the entire retina not just the central retina. This is particularly useful in managing the effects of peripheral retinal disease which is often seen in patients with diabetes or retinal detachments or tears.
