Overview
Orbital cellulitis may be classified by various features of the disease. In 1970, Chandler's classification was created to describe five groups of complications of sinusitis by invading the surrounding tissue.[1]. Alternative ways of classifying the disease is by the microbial family of the offending pathogen (Bacterial vs. Fungal), or by the management protocol (Medical vs. Surgical therapy).

- Abscess vs. No Abscess:
Chandler's Classification of Complications of Sinusitis[1]
- Stage I: Preseptal Cellulitis - Also known as periorbital cellulitis, this condition is not classified as true orbital edema. It is rarely extends to become true post-septal orbital edema. It is characterized by lid edema, and no changes in visual acuity or ocular movements.
- Stage II: Orbital cellulitis - Also known as postseptal cellulitis or true orbital cellulitis. Diffuse orbital inflammation without abscess formation.
- Stage III: Subperiosteal abscess
- Stage IV: Orbital abscess
- Stage V: Intracranial involvement/Cavernous Sinus Thrombosis.
