Optic Nerve Sheath Ultrasound in Giant Cell Arteritis

The patients are examined in a supine relaxed position. The probe is gently placed on the closed eyelid with a standard ultrasound gel and adjusted to a suitable angle to display the optic nerve entry into the eyeball. Measurements are done 3mm distal to the posterior aspect of the ocular globe. Ultrasosonographic 14L5 probe is used with a safe thermal index, mechanical index and intensity limit. All patients will also undergo a bedside fundoscopic examination. Official ophthalmology consultation will be requested in patients with visual symptoms or abnormal fundoscopy.
