About DME

As with all macular diseases, the main symptom of DME is the loss of central vision (the ability to see things straight ahead). However, you may also notice changes in your colour vision and fine detail.

The symptoms of DME are very similar to those of other macular diseases. The key differentiator is whether you also have diabetes. DME symptoms can develop slowly, yet early detection is key. Therefore, if you are diabetic, you will have regular eye checks, and it is important to notify your doctor if you notice any of the following.^1,2

6 boxes. The first contains a line drawing of two eyes and the text “blurred or double vision”, the second has three circles and the text “seeing dark spots or smudges… especially noticeable in the morning”, the third has a drawing of a rainbow and the writing “distorted or faded colours”, the fourth has wavy lines and “straight lines appearing wavy”, the fifth has a line drawing of the sun and the text “light sensitivity” and the last has a line drawing of a head with a spiral inside and a question mark and the text “visual hallucinations… known as Charles Bonnet syndrome”.

If you notice any changes in your vision, consult a specialist immediately.
