Retinal Photography

I had a retinal photograph today. How amazing is technology. It is a photo of the back of your eye. My Optician showed me the photos which showed the retina, optic nerve and blood vessels. It only took five minutes or so to have, no drops, and painless (thank heavens, I am hopeless with my eyes, someone has to sit on me to get drops in). My eyes may or may not be showing extreme early signs of glaucoma so this photograph will be stored and compared to another in 12months time to see what, if any, changes have taken place. This way subtle changes can be seen that could not have been detected before. Glaucoma can now be found and treated in its early stages. Thank you to the inventor.
