Imaging of Painful Ophthalmologic Disorders.

Area of Science:

• Ophthalmology
• Radiology
• Medical Imaging

Background:

• Ophthalmologic disorders can cause significant pain and complications.
• Accurate diagnosis relies on effective cross-sectional imaging techniques.

Purpose of the Study:

• To outline the diagnostic utility of CT and MRI in ophthalmologic disorders.
• To differentiate the roles of CT and MRI in evaluating orbital infections and other eye conditions.

Main Methods:

• Review of cross-sectional imaging modalities, specifically computed tomography (CT) and magnetic resonance imaging (MRI).
• Analysis of CT and MRI applications in diagnosing orbital infections, cellulitis, abscess, optic neuritis, endophthalmitis, and fungal rhinosinusitis.
• Evaluation of CT angiography for carotid cavernous fistula detection.

Main Results:

• CT is a first-line imaging tool for suspected orbital infections, distinguishing preseptal from orbital cellulitis and detecting abscesses.
• MRI provides superior orbital soft tissue evaluation, crucial for optic neuritis, endophthalmitis, and invasive fungal sinusitis with orbital spread.
• CT angiography is the preferred noninvasive method for carotid cavernous fistula diagnosis.

Conclusions:

• CT and MRI are indispensable cross-sectional imaging tools for diagnosing painful ophthalmologic conditions.
• Each modality (CT and MRI) has distinct strengths in evaluating specific orbital and ocular pathologies and their complications.
• CT angiography is the gold standard for noninvasive assessment of carotid cavernous fistulas.
