What are retinal vein occlusion symptoms?
Sometimes there may be no retinal vein occlusion symptoms at all. It may just be an incidental finding by an optometrist who has noticed that there’s a pattern of haemorrhages or changes along the blood vessels.
This is commonly found in diabetics. For example, there may be a small localised vein occlusion that doesn’t interfere with their central vision. If the vein occlusion does involve the macula, the centre part of the retina, the vision can drop quite dramatically.
In a central retinal vein occlusion, depending on the degree of damage, the vision can vary from losing a few letters on the chart, to only being able to see shapes.
In a branch vein occlusion, patients may notice that half an object is missing or disturbed and that the bottom half or the top half is relatively much clearer.
If an abnormality is identified with your vision, it is important to get this tested straight away, so that the exact cause can be understood and treated properly. Prompt treatment is associated with a better outcome of the long term.
