Symptoms of RVO

Introduction to RVO

As the effects of RVO result from macular oedema, RVO shares its symptoms with other macular diseases, such as DME. The main symptom being the loss of central vision, as well as^1,2,3:

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”.

Usually, RVO will only effect one eye as it is unlikely for veins in both to become blocked simultaneously. As a result, the other eye may compensate, making changes in your sight harder to notice.¹ That being said, early detection is key – allowing you to manage RVO before the damage can progress further. So if you notice any of these symptoms, notify your doctor or optician.

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