In macular degeneration, the retina at the back of the eye slowly degenerates. It affects mainly the sensitive central area of the retina, so as it progresses sharp central vision is lost. Macular degeneration mainly affects people over 70, and sometimes family history or other medical conditions will increase the risk.

New research has suggested that diet may play a role in reducing the risk of macular degeneration. Spinach and Kale contain an ingredient that is protective against macular degeneration. Omega 3 fish oil also seems to be beneficial. Conversely, processed fats and smoking increase the risk.

Over the last few years there have also been some new treatments with laser therapy and intra-ocular medication that helps certain forms of macular degeneration.
