Retinal pictures are taken by a Fundus camera. Below are examples of eye diseases which were captured by retinal pictures.
Structures seen in the retina include the optic nerve (peripheral vision), macula (central vision), arteries and veins. This type of scan of the eye is unique as it is the only place in the body where we can see arteries/veins without cutting someone open!
Glaucoma is a slow progressing disease which can slowly cause deterioration of your peripheral vision without any symptoms – only signs. This is why eye exams are important. One of the signs we look for is the appearance of the optic nerve head.
Age Related Macular Degeneration
Macular degeneration can cause wavy central vision, especially when looking at faces. Foods to eat to protect the macula and ocular health in general include fatty fish (omega 3 and omega 6 fish fatty acids) and green leafy vegetables such as spinach, kale, broccoli, and bok choy. UV protection is also essential in protecting the macula.
How does diabetes affect the eye? When your blood sugar fluctuates, your vision fluctuates. More importantly, Optometrists are concerned as diabetes can cause bleeding in the back of your eye. It is very important to monitor your blood sugar, take medications on time, exercise, and regularly visit your primary care doctor.
