  • Painful swelling of the parotid one or both parotid glands

Cause

  • Viral infection
    • Historically the number one cause was the mumps
    • Parainfluenza and Epstein barr are the most common
    • HIV
  • Bacterial infection
    • Staph Aureus is the most common bacteria
  • Autoimmune disease
    • Sjogrens
  • Blockage
    • Stone
    • Mucus plug
  • Dehydration

Clinical Presentation

  • Facial swelling
  • Facial pain
  • Difficulty swallowing

Labs, Studies and Physical Exam Findings

  • Clinical diagnosis

Treatment

  • Supportive care
  • Appropriate antibiotics

Glaucoma

  • Increased intraocular pressure leading to damage to the optic nerve.
  • Aqueous humor is constantly being produced within the eye. It also is constantly draining out.
  • The four major types of glaucoma include
    • Open angle glaucoma which is a the chronic form
    • Closed angle glaucoma which is an acute clogging of the drainage of aqueous humor
    • Congenital glaucoma
    • Secondary glaucoma – caused by systemic diseases, trauma or steroids.

Risk Factors

  • Advancing age
  • African American
  • Family history of glaucoma
  • Diabetes
  • HTN
  • Hypothyroidism
  • Long term use of corticosteroids

Clinical presentation

  • Open angle glaucoma
    • Insidious, often no symptoms
    • Gradual loss of peripheral vision
  • Acute angle closure glaucoma
    • Pain
    • N/V
    • Blurred vision
    • Halos around lights
    • Photophobia

Labs, Studies and Physical Exam Findings

  • Open angle glaucoma
    • Tonometry: IOP > 22
    • Bowing of the iris
    • Visual field test will show decreased peripheral vision
    • Visual acuity should always be tested
    • Fundoscopic exam
      • look for vessels bending over the edge of the disc
      • cup:disc ratio of >0.5
  • Closed angle glaucoma
    • Tonometry: IOP > 22, in an acute phase pressures can be between 40 and 80 mmhg
    • Fixed mid dilated pupil
    • Red or hazy eye
    • Fundoscopic exam
      • look for vessels bending over the edge of the disc
      • cup:disc ratio of >0.5

Treatment

  • Medications
    • Prostaglandins to promote drainage
      • Latanoprost ( Xalatan)
      • Bimatoprost (Lumigan)
    • Beta Blockers to decrease production of aqueous humor
      • Timolol
      • Betaxolol
    • Alpha Adrenergic agonists to decrease production of aqueous humor and promote drainage
      • Apraclonidine (iopidine)
      • Brimonidine (Alphagan)
  • Surgical correction
    • Laser trabeculoplasty – open the clogged channels
    • Filtering trabeculectomy – removing a piece of the sclera to allow drainage
