jaw claudication (65%)
visual disturbances:
- amaurosis fugax
- blurring
- double vision
- vision testing is a key investigation in patients with suspected temporal arteritis
- secondary to anterior ischemic optic neuropathy
tender, palpable temporal artery
around 50% have features of PMR: aching, morning stiffness in proximal limb muscles (not weakness)
also lethargy, depression, low-grade fever, anorexia, night sweats

Q

Mx temporal arteritis?

A
  • urgent high-dose glucocorticoids should be given as soon as the diagnosis is suspected and before the temporal artery biopsy (40-60mg prednisolone) -> PPI AND alendronate for 2y
  • no visual loss: high-dose prednisolone is used
  • evolving visual loss: IV methylprednisolone is usually given prior to starting high-dose prednisolone
  • urgent ophthalmology review same day, visual damage is often irreversible

other treatments:
bone protection with bisphosphonates is required as long, tapering course of steroids is required
low-dose aspirin is sometimes given to patients as well, although the evidence base supporting this is weak
