Diagnosis and Treatment of Orbital Disorders

Orbital disease is less common than eyelid and lacrimal disease, and should be managed by a clinician experienced in this subspecialty. The correct diagnosis requires a careful history and examination, and other investigations such as an orthoptic assessment, orbital ultrasound, and imaging (typically CT) are often necessary. Depending on the underlying cause, the symptoms of orbital disease can vary from mild bulging of the eye, often unnoticed by the patient, to marked swelling, inflammation, ocular ache, double vision and even loss of vision. Treatment of orbital disease depends on an accurate diagnosis, and can include tablets or other medications to suppress the immune system, radiotherapy, or orbital surgery. The latter is not without risk to the vision, this depending on the extent and depth of surgery.
