Blepharitis is the inflammation of the eyelids, in which the eyelids become red, itchy and irritated. This is due to the overgrowth of bacteria along the lid margins. It can affect people of all ages. By using a microscope, we can take a photo of your eyelashes to show you the blepharitis. Crusting of the eyelids , also known as “bak sai” or “yan shi” is a common symptom seen in people suffering from blepharitis.
There are 2 types of blepharitis:
1) Anterior blepharitis: Occurs at the front surface of the lid margin, at the root of the eyelashes.
2) Posterior blepharitis: Occurs on the inner lid margin that touches the eyeball.
