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

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.

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