Age related macular degeneration or ARMD is the most common cause of irreversible vision loss for people over the age of 60.

If your eyelid rims are red and irritated, if they burn and itch or if you've noticed an oily discharge or scaly skin around them, you may have an inflammatory problem called "blepharitis". Some people describe it as "psoriasis of the eyelids".

A small area of redness and pain on the margin of your eyelid may indicate that you have a stye, known in medical terms as an external hordeolum. A stye is a blocked gland at the edge of the lid that has become infected by bacteria, usually Staphylococcus aureus.
