What are the risks with these injections? 

As with any medical procedure, there is a small risk of complications that may occur following an intra-vitreal injection. Most complications that might occur are from the injection itself, rather than the drug. 

For most patients, the benefit of the treatment outweighs the small risk of injection injury.  This should have been discussed with you when you started your course of treatment.

The following are the main potential risks and side effects of anti-VEGF eye drug injections, but this is not a complete list of all risks. These risks are all rare. Significant loss of vision due to this treatment is very uncommon. 

• You might notice some discomfort and redness and your vision may be blurred for the first few days after your treatment and this usually settles between 24 – 48 hours. 
• You may notice floaters in your eye which usually disappear after a few days.

• Sometimes the eye may feel gritty and watery.  This should settle down after a day. 
• It is recommended that you take your normal analgesia after the injection if you eye feels uncomfortable 
• Serious eye infection - If your eye becomes progressively red, sensitive to light, swollen with increased pain, or if your vision gets worse after the injection treatment, you must seek medical help and advice from an ophthalmologist. 

This might indicate infection and normally occurs within the first few days after the injection.  The risk is minimal, but this is the most important complication, and you must contact us immediately if you are concerned about this.
