Abstract
Inflammatory changes in the eyelids are of bacterial or viral origin. Bacteria affect the eyelid margins in various ways and can be the cause of stye and chalazion.
Viral conjunctivides are caused by herpes viruses. Serious eyelid diseases include abscess or phlegmon that can both cause orbital inflammation.
Conjunctivides are aetiologically and clinically varied. They are divided into infectious (bacterial, viral, chlamydial, fungal) or non-infectious (allergic or toxic).
Acute bacterial infections are characterized by discharge of pus and eye redness. Viral inflammations are accompanied by preauricular node swelling and the cornea may also be involved.
Allergic conjunctival reactions take the form of seasonal or perennial inflammations, less frequently of atopic or vernal conjunctivitides.
