Q

what is the difference between open and closed angle glaucoma? [2]

A

Open angle Glaucoma: flow reduced due to degeneration and obstruction of trabecular meshwork.

Closed Angle Glaucoma: iridocorneal angle is completely closed. Flow of fluid inside the eye cannot pass through the canal of Schlemm.

Q

A 44-year-old gentleman presents to the emergency department having been hit by a car while crossing the road. The paramedics tell you that he was fully conscious at the scene, but while travelling in the ambulance his consciousness level seemed to deteriorate. He is now responsive to voice but is only responding in single words. After stabilising the patient, you request an urgent CT scan of the head. This shows the patient has an extradural haemorrhage. A common cause of extradural haemorrhage is rupture of the middle meningeal artery. The middle meningeal artery runs along the deep surface of the cranium, with its anterior division running close to which of the following points on the cranium?

Pterion
Asterion
Lambda
Bregma
Nasion

Facial

Abducens
Trochlear
​Trigeminal

The trochlear nerve has a relatively long intracranial course and this makes it vulnerable to injury in head trauma. Head trauma is the commonest cause of an acute fourth nerve palsy. A 4th nerve palsy is the commonest cause of a vertical diplopia. The diplopia is at its worst when the eye looks medially which it usually does as part of the accommodation reflex when walking down stairs.

A General Practitioner performs an eye examination to a 44-year-old lady. When shining a light on the left eye, the direct pupillary reflex is normal while the consensual response of the right eye is absent. Direct and consensual reflexes are normal when the light is shone into the right eye.

Where is the most likely site of the lesion?

Right retectal nucleus
Left optic nerve
Right Edinger-Westphal nucleus
Left Edinger-Westphal nucleus

Q

A 19-year-old man is involved in a high-speed collision on a motorway. He sustains a head injury and is brought into hospital, intubated and ventilated, and undergoes a computed tomography (CT) scan of his head.

The scan shows an area of cerebral hemisphere being forced inferiorly towards the brainstem. This is reported by the radiologist as ‘uncal herniation’.

Through what structure, made of dura mater, is the brain herniating?

Falx cerebelli
Falx cerebri
Sella diaphragm
Tentorium cereblli
Trigeminal cave

Q

what is tonometry? [1]

A

Tonometry is a diagnostic test that measures the pressure inside your eye, which is called intraocular pressure (IOP). This measurement can help your doctor determine whether or not you may be at risk of glaucoma.

Q

what are the different drug types & mechanims to treat glaucoma? [5]

A
  • Prostaglandin analogs increase outflow of aqueous humor through canal of Schlemm
  • Beta-adrenergic receptor antagonists decrease aqueous humor production
  • Alpha2-adrenergic agonists work by a dual mechanism, decreasing aqueous production and increasing outflow.
  • Parasympathomimetic agonists and anticholinesterases work by contraction of the ciliary muscle, which opens the canal.
  • Carbonic anhydrase inhibitors lower secretion of aqueous humor by inhibiting carbonic anhydrase in the ciliary body.

Imaging demonstrates infarction of the ventral spinal cord betwen T10 and L2 due a clot in a large, left sided segmental medullary artery at T10. What is the name of this artery?

This artery is commonly known as the artery of Adamkiewicz. It is the largest and most important segmental medullary artery and is responsible for most of the arterial supply to the lower thoracic and lumbar spine. Damage to this artery therefore can cause catastrophic neurological sequelae.

Q

what do the following do?

Superior rectus: [3]

Inferior rectus: [3]

Inferior oblique: [3]

A

Superior rectus: elevation, adduction and intorsion

Inferior rectus: depression, adduction and extorsion

Superior oblique: Depression, abduction and intorsion

Inferior oblique: Elevation, abduction and extorsion

The action of the medial and lateral recti is straightforward: medial rectus adducts the globe (eyeball) and lateral rectus abducts the globe, without elevation or depression.

The superior and inferior recti act to elevate and depress the globe respectively. However as the orientation of the muscle is not inline with the angle of the orbit, the recti muscles also create secondary actions.

A set of observations taken immediately are:
Heart rate: 36 bpm
Blood pressure: 60/42 mmHg
Sats: 96%
Temperature: 36.7ºC

The GP suspects carotid sinus syndrome.

Q

what is romberys test?

what is it testing?

of what assumption does it work off?

A

used to quickly screen for evidence of sensory ataxia (i.e. non-cerebellar causes of balance issues).

Romberg’s test is based on the premise that a patient requires at least two of the following three senses to maintain balance whilst standing

Proprioception: the awareness of one’s body position in space.

Vestibular function: the ability to know one’s head position in space.

Vision: the ability to see one’s position in space.

Q

An 88-year-old diabetic woman with known vascular dementia is telling her carers she cannot feel the left hand side of her body.

Her cranial nerve examination is unremarkable. Upon neurological examination of her upper limbs and lower limbs there is a dense sensory loss to light touch, vibration and pain on the right. Moreover, she cannot detect temperature change and her joint position sense is impaired on the right. A CT head scan reveals an area of infarction in the region of the lateral thalamus on the left side.

Which lateral thalamic nucleus has been affected by this stroke?

Lateral geniculate
Medial geniculate
Ventral anterior
Ventral lateral
Ventral posterior

Which lateral thalamic nucleus has been affected by this stroke?

Lateral geniculate
Medial geniculate
Ventral anterior
Ventral lateral
**Ventral posterior

Ventral posterior is correct as this thalamic nucleus is where axons from the medial lemniscus (relating sensory axons from the dorsal columns in the spinal cord to the medulla, where they decussate in form of medial lemniscus from medulla to cortex) and spinothalamic pathway project to, on their journey towards somatosensory areas of the cortex. These pathways detect light touch, proprioception, vibration and pain/temperature respectively. Hence a lack of sensation on the right side of the body with left lateral ventral posterior thalamic nuclei lesions.**
