Treatments considered will vary depending on the type of retinal vein occlusion, its location, severity and length of time.
If the centre of the retina has not been affected and vision remains good, no treatment may be an option. In limited cases, some mild retinal vein occlusions can resolve without treatment over many months.
- Anti-VEGF (Anti-Vascular Endothelial Growth Factor) injections involves medication to shrink the pooled blood vessels and dry up the excess fluid. This medication is administered via intravitreal injection.
- Laser treatment is occasionally used as an adjunct treatment with anti-VEGF injections to help control swelling and bleeding.
- Vitrectomy surgery may be recommended in cases where there has been bleeding into the vitreous cavity or a membrane (scar tissue) develops on the surface of the retina.
The earlier treatment is commenced, the greater the chance of preserving vision, as the longer the retina is swollen, the more permanent damage is done.
