Retinal Vein Occlusion

Retinal Vein Occlusion

This is blockage of a vein within the retina causing localised haemorrhages or ‘clots’. If the major vein is affected ie the central vein, then the vision may be severely affected. If only a smaller vein is affected this will only cause part of the vision to be blurred. The treatment depends on the type of ‘vein occlusion’ and severity.

Early intervention provides the best results.

It is now recommended to start treatment with intravitreal injections as soon as possible. This may be with a steroid, lucentis, aflibercept or avastin.Laser may be needed

High blood pressure is probably the commonest cause.
