16
Q

Management of CRAO (3)

A

Only effective within 12-24 hours

  • Ocular massage
  • Paper bag breathing (> vasodilation)
  • Use carbonic anhydrase inhibitors etc to lower IOP
17
Q

Signs in CRVO (2)

A

Flame haemorrhages

Cotton wool spots

18
Q

Management of CRVO

A

Depends on whether there are signs of ischaemia + neovascularisation
If neovascularisation = use laser pan-retinal photocoagulation

19
Q

Association with anterior ischaemic optic neuropathy

A

Can be associated with GCA

20
Q

Management of acute angle closure glaucoma

A

IV acetazolamide

21
Q

Management of HZV Ophthalmicus

A

Oral aciclovir

22
Q

Retrobulbar neuritis

A

Won’t see swollen disc

Will still have features of optic neuritis

23
Q

Association with CN III palsy (Vascular)

A

Posterior communicating aneurysm

24
Q

Two components of grading diabetic retinopathy

A

Retinal neovascularisation

Macular oedema

25
Q

Diabetic retinal screening programme

A

Starts at 12 years old, annually

26
Q

Management of corneal foreign body

A

History
Slit Lamp
Cotton wool bud or needle
Give topical chloramphenicol

27

30
Q

Complications of corneal transplant (2)

A

Astigmatism

Graft rejection

31
Q

Latanoprost

  • Drug Type
  • Mechanism
A

= prostaglandin analogue, increased uveoscleral outflow

32
Q

A

= irrigate IMMEDIATELY

33
Q

What is amblyopia?

A

Visual development disorder which can result from accommodative esotropia (squint)

34
Q

Orbital floor # nerve associated

A

Infraorbital - can be damaged, also supplies part of the cheek

35
Q

Brimonidine

  • Drug Type
  • Mechanism
A

= sympathomimetics, increases uveoscleral outflow

36
Q

Management of acute angle glaucoma

A

IV acetazolamide
Topical lantaprost
Topical pilocarpine

37
Q

Acute angle closure glaucoma
VS
Anterior uveitis

A

Acute angle closure glaucoma = pupil dilated

Anterior uveitis = small pupil
