Critical
Visible or palpable, well-defined, subcutaneous nodule in the eyelid. In some cases, a nodule cannot be identified.

Definitions
Chalazion: Focal, tender, or nontender inflammation within the eyelid secondary to obstruction of a meibomian gland or gland of Zeis.
Hordeolum: Acute, tender infection; can be external (abscess of a glands of Zeis on eyelid margin) or internal (abscess of the meibomian gland). Usually involves Staphylococcus species and occasionally evolves into preseptal cellulitis.
NOTE: |
A steroid injection can lead to permanent depigmentation or atrophy of the skin at the injection site, especially in dark-skinned individuals. Similarly, a vigorous injection can rarely result in retrograde intra-arterial infiltration with resultant central retinal artery occlusion. Because of these risks, some manufacturers of injectable steroids (e.g., triamcinolone and betamethasone) have historically recommended against their use intraocularly and in the periocular region. Off-label use of the medications should include a detailed discussion between physician and patient. |
