Vitamin B12 with eye injections for blocked retinal vein
Treatments studied
Part of Eyes & vision, Heart & circulation clinical trials.
This trial tests if adding mecobalamin (a form of vitamin B12) to standard anti-VEGF eye injections helps people with vision loss caused by a blocked vein in the retina. You must have swelling in the back of the eye and have had no prior treatments for this condition.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be between 18 and 80 years old
- You have a blocked vein in the retina with swelling in the center of the eye, confirmed by an OCT scan
- Your vision is between 20/400 and 20/40 on an eye chart
- You have never had treatment for this condition, including eye injections, laser, or steroid therapy
- You do not have other eye diseases that cause swelling, like diabetic retinopathy or uveitis
- You are not pregnant, breastfeeding, or have uncontrolled health issues like high blood pressure or diabetes

This trial tests a new eye injection (GenSci148) for people with wet age-related macular degeneration, diabetic macular edema, or retinal vein occlusion. The injection may help reduce swelling and abnormal blood vessel growth in the retina, which can improve or stabilise vision.
This trial tests a new medicine called SMO1 for people with vision loss and swelling in the eye caused by a blocked vein in the retina. It involves regular eye injections to see if the medicine can reduce swelling and improve vision.
This trial tests a tiny needle injection into the artery to dissolve a blockage in the eye's main blood supply. It may help restore vision if the blockage happened within the past week.
This trial tests an eye injection called OLN324 for diabetic macular edema, a condition where fluid builds up in the retina and blurs vision. The treatment aims to improve vision and reduce swelling in the eye.
This Phase 1 trial tests whether BBC1501, an injection given into the eye, is safe for people with wet age-related macular degeneration (nAMD). It mainly looks at side effects and whether the study injections can be given safely in patients who still have active disease despite prior anti-VEGF treatments.
This study looks at how repeated eye injections of a drug called bevacizumab affect chemicals in your blood that relate to heart health and inflammation. Researchers want to understand if these eye injections might impact your cardiovascular risk.
