Imaging of orbital disorders.

Area of Science:

• Ophthalmology
• Otorhinolaryngology

Background:

• Orbital diseases encompass a range of conditions affecting the eye socket.
• Classification by etiology provides a structured approach to understanding these diverse pathologies.

Purpose of the Study:

• To categorize orbital diseases based on their etiological origins.
• To provide a differential diagnosis framework for orbital masses and inflammatory conditions.

Main Methods:

• Review of orbital disease classification by etiology.
• Discussion of common infectious and noninfectious inflammatory orbital conditions.
• Analysis of orbital mass lesions based on location, patient age, and tumor type.

Main Results:

• Orbital diseases are grouped into infectious (e.g., orbital cellulitis) and noninfectious inflammatory conditions (e.g., thyroid orbitopathy, idiopathic orbital inflammatory syndrome).
• Orbital masses include lacrimal gland tumors (lymphomas, epithelial lesions), extraocular muscle tumors (lymphoma, metastases), intraconal fat tumors (hemangiomas, schwannomas), and globe tumors (retinoblastomas, melanomas, metastases).
• Diagnostic considerations for orbital masses are influenced by lesion location and patient demographics.

Conclusions:

• Etiological classification aids in understanding and diagnosing orbital diseases.
• Recognizing the distinct presentations of inflammatory conditions and various orbital tumors is crucial for effective management.
