Below shows redness of the top part of the eye. This is called Superior Limbic Keratoconjunctivitis (SLK). In middle-aged women who don’t wear contact lenses it can be due to hyperthyroid. In younger patients it is often due to irritation and inflammation stemming from contact lens wear. It can sometimes be difficult to manage with a combination of lubricants, steroids, anti-allergy drops, contact lens and solution change, cylosporin and others.
