Visual Outcomes in Five Different Approaches for Treatment of Central Retinal Vein Occlusion

Central Retinal Vein Occlusion is a disease with the main draining vein of the retina, in the eye, becomes blocked). This results in backup of blood, bleeding and swelling in the retina, and subsequent vision loss.

This study examined which current treatment modality improves final outcome. The best treatment was a radial optic neurotomy combined with triamcinolone injection in the eye. A radial neurotomy is performed by making radial incisions around the optic nerve on the nasal side of the nerve (the side closest to the nose). Somehow this takes pressure of the central retinal vein, enabling blood flow. Triamcinolone is a type of steroid that decreases inflammatory response.
