Test
Result
Test

Not useful in diagnosing styes or chalazia. However, if there is a question of dacryoadenitis (infection or inflammation of the lacrimal gland) or dacryocystitis (infection of the lacrimal sac), CT scanning may be appropriate to confirm the diagnosis and exclude other, more serious pathology such as orbital cellulitis. Such patients usually have more diffuse swelling, oedema, and erythema of the lid and peri-orbital region.[13]​​

Result

no significant findings in stye or chalazion; evidence of lacrimal involvement in dacryoadenitis or dacryocystitis, or peri-orbital or orbital cellulitis
