Q

uveitis

A

o Steroid eye drops
o Use cycloplegics to relax ciliary bodies to dilate the eye -> iris can get stuck to cornea -> cycloplegics stop this

Q
A
  • Angle closure glaucoma
  • > 30mmHg measured using Goldmans tonometry
  • Fixed eye- key
  • Vision: halo sign

Management
- Timolol
- Pilocarpine
- Acetazolamide (TAP)
- Laser iridotomy
o Works by producing a hole, allowing an alternative hole for the aqueous to flow

Q

pathophysiology of acute angle closure glaucoma

A

When pupil dilates the iris crumples up to the corner i.e. if you are in a dark room like a cinema -> stops drainage -> can get stuck in this position therefore pupil dilatation

Q

management of glaucoma

A
  • ABC reduce production of aqueous from ciliary body
  • PAP -> increases flow through trabecular network
  • Mannitol is last resort

Q

Squints (strabismus) in adults

A
  • CN palsy
  • Thyroid eye
  • Blow out fracture
20
Q

Squints in children

A
  • Congenital misalignment
21
Q

Amblyopia vs strabismus

A

Strabismus is a problem with eye alignment, in which both eyes do not look at the same place at the same time. Amblyopia is a problem with visual acuity, or eyesight.

22
Q

cranial nerve examintion

A

go throught CNs one by one

23
Q

Olfactory

A
  • Smell
  • Causes
    o Cribriform plate fracture
    o Covid
24
Q

Optics

A
  • Inspect pupils
  • visual acuity
  • pupillary reflexes
  • colour vision
  • visual fields
  • fundoscopy
25
Q

visual acuity

A

Snellen (6m)
- Cover left eye first and read down to lowest line they can
- Distance from the chart
- Lowest full line that can be read correctly +- additional letters
- E.g. 6/24-1 (would be can reqad the 2 letters on line 24 but not the 3rd

26
Q

noral visual acuity

A
  • 6/6 is normal (20/20 in feet)
  • Driving limit 6/12
27
Q

pupillary reflexes

A

1) Direct and indirect
2) Relative afferent pupillary defect (RAPD- diff to indirect)

28
Q

Relative afferent pupillary defect (RAPD) (different to indirect)

A
  • If one eye not constricting as well as the other (will look way more dilated even if it seemed to constrict on the direct and indirect)
  • Swing light between eyes to compare (working CN eye will constrict more than the defective oen)
  • Damaged eyes looks like its dilating
29
Q

colour vision

A

colour chart

30
Q

visual fields test

A
31
Q

Cranial nerves oculomotor, trochlear , abducens

A
  • Eyelids (CN 3)
  • Eye movements
32
Q

Trigeminal nerve

A
  • Touch – sensory (ophthalmic, maxillary, mandibular division)- cotton wool
  • Motor assessment
    o Palpating Masseter muscle whilst clenching the teeth
  • Corneal reflex
33
Q

Facial nerve

A
  • Sensory assessment
    o Anterior 2/3 of tongue
  • Motor assessment
    o Facial expressions
34
Q

Vestibulocochlear nerve

A
  • Gross hearing assessment
  • Rinne and Webers test
35
Q

Glossopharyngeal and vagus

A
  • Swallow assessment
  • Gag reflex
  • Ask to cough
36
Q

Accessory nerve

A
  • Shrug shoulders
  • Can you push against my hand on face
37
Q

Hypoglossal

A
  • Put out tongue

look for direction and fasiculation

38
Q

uvula

A

tip of soft palate
o Muscular -> to help move food
o Vagus nerve -> ask them to say ahhh -> opposite direction to CN palsy (can cause nasal regurgitation, hot potato voice)

39
Q

palatine tonsils

A

(part of Waldeyeres ring)
o Tonsilitis
o Quinsy – peritonsillar abscess (opening mouth is painful, halitosis, hot potato voice (not neurological just due to physical distortion, systemic symptoms, unilateral distortion of soft palate)
o Stertor -> oropharynx – snoring noise

40
Q

Oropharyngeal cancer

A
  • Squamous
  • Metastasise to lymph nodes
  • RF
    o Beetle nut gum
    o HPV
    o Smoking
    o Drinking
  • Presentation
    o Lymphadenopathy
    o Ulceration
    o Hoarseness
    o Dysphagia
41
Q

Lymphadenopathy

A
  • Infection
  • Malignancy
  • Salivary glands
    o Infections and inflammations e.g. parotitis
    o Stones
    o Cancers- parotid more likely , facial nerve paralysis (ipsilateral facial droop
42
Q

role of larynx

A
  • Airway protection e.g. close off airway during swallow, coughing
  • Speech
43
Q

Anatomy of the larynx

A

Epiglottis is anterior -> pointing to the front
1. Aperture (gap)
2. True vocal cords- lighter in colour
3. Piriform fossa

44
Q

route of the recurrent laryngeal nerves (diff on each side)

A

Right Recurrent laryngeal nerve – Hooks underneath the right subclavian artery, then ascends towards to the larynx. It innervates the majority of the intrinsic muscles of the larynx.

Left recurrent laryngeal nerve – it hooks under the arch of the aorta, ascending to innervate the majority of the intrinsic muscles of the larynx.

45
Q

retropharangeal abscess

A

Infection in the retropharyngeal space is usually secondary to an upper respiratory tract infection (e.g. nasal cavity, nasopharynx, oropharynx) and is most commonly seen in children, usually under the age of 5 years. Infection in this space may

develop into an abscess.

A retropharyngeal abscess can present with a variety of signs and symptoms including a visible bulge on inspection of the oropharynx, sore throat, difficulty swallowing, stridor, reluctance to move their neck and a high temperature. It is important to recognise and treat early.
