IS IT THIS? - reference only, to read alongside your own examination
  SYMPTOMS - what the patient reports (3)
    - Patients report a drooping eyelid, cosmetic concern, reduced vision, a tilted head posture,
      lid movement linked to jaw motion, eye heaviness, and double vision looking up  [blurred
      vision · double vision · ptosis]
    - Eyelid drooping that varies from day to day raises suspicion for myasthenia gravis
    - A steadily worsening droop can be seen in chronic progressive external ophthalmoplegia
      [ophthalmoplegia]
  SIGNS - what you find (5)
    - Reduced eyelid-lifting muscle strength, lid lag on downward gaze, a weak or absent eyelid
      crease, and a wider eye opening in downgaze point to the congenital form
    - Severity is graded by the difference between the eyelid margins: 2 mm or less is mild, 3 mm
      moderate, and 4 mm or more severe
    - Lifting the drooping lid and watching whether the other eyelid then droops distinguishes true
      ptosis from pseudoptosis  [ptosis]
    - A good Bell reflex shows less than one-third of the cornea when the closed eye is gently
      lifted
    - Phenylephrine drops test Muller muscle function by stimulating its adrenergic receptors
  IF NOT THIS - what else fits (5)
    - Neurogenic ptosis stems from nerve problems such as third-nerve palsy, Marcus-Gunn jaw
      winking, Horner syndrome, multiple sclerosis, or ophthalmoplegic migraine
    - Normal muscle strength with a stretched or torn levator tendon points instead to aponeurotic
      ptosis
    - Extra weight on the lid from chalazia, swelling, a tumor, or redundant skin can cause
      mechanical ptosis
    - A myoneural junction disorder such as myasthenia gravis produces myogenic ptosis
    - A small shrunken eye, a sunken eye, upward eye deviation, or an abnormally small eye can mimic
      ptosis on the same side

1. NO DRUG THERAPY IN PRIMARY CARE (REFERRAL & ADVICE)    [1st line]
   Adult    Broad symptom bucket covering abnormal blinking and ptosis (drooping eyelid). Ptosis in
            particular can be a sign of serious neurological or neuromuscular disease, so there is
            no single drug for this code; the GP's job is recognising which presentations need
            urgent work-up versus routine ophthalmology referral. - Refer, with advice
   Peds     Children follow the same pathway: recognise and refer. No primary-care medicine is
            implied.

   Caution  No medicine is prescribed for this in primary care - this entry is for recognition and
            referral. Anything given is decided by the service it is referred to.
            RED FLAG - If severe ptosis is not detected and treated on time, it can lead to severe
            amblyopia and torticollis.
            RED FLAG - Sudden ptosis, especially with double vision or a dilated pupil (possible
            third cranial nerve palsy or stroke - an emergency), or ptosis that worsens through the
            day or with fatigue (suggests myasthenia gravis): refer urgently.
