When do you refer to periorbital cellulitis?
The CREST guideline recommends urgent referral to ophthalmology for people with suspected orbital or periorbital cellulitis, as it is vital to distinguish between the two due to potential complications from orbital cellulitis (decreased ocular motility, decreased visual acuity and cavernous sinus thrombosis) [CREST.
What is the difference between blepharitis and chalazion?
A chalazion is a small firm bulge in the eyelid caused by a blocked opening or infection of the oil producing glands located in the upper or lower eyelids. Chalazia are frequently associated with a condition called blepharitis. Chalazia may be uncomfortable, look abnormal, or interfere with vision.
