Changes to the retina caused by diabetic retinopathy can often be entirely symptomless in the initial stage of the disease. This can mean that it takes longer to diagnose unless regular monitoring of the backs of the eyes is carried out.
As it progresses, retinopathy can lead to deterioration of vision and varying vision symptoms. If you notice clear changes in your vision before you are due a screening appointment, contact your treatment provider, who can assess the severity of the symptoms and how urgently you should be examined by a doctor.
If you experience any of the following symptoms, please contact your treatment provider to review your situation:
sudden deterioration in vision or visual field defects
distortion of straight lines or objects appearing larger or smaller than they are
visual snow or sudden and abundant oscillating fogging in the field of vision
severe or dull eye pain.
