How would you manage Hypertensive retinopathy?
Treat hypertension
What are symptoms of retinal artery occlusion?
Sudden painless loss of all vision (central) or part of vision (branch)
What are features of retinal artery occlusion on fundoscopy?
- Swollen, pale (oedematous) retina
- Cherry red spots - macula

How wuld you manage retinal artery occlusion?
Reduce IOP within 6 hours

What are features of retinal detachment on fundoscopy?
Grey opalescent retina, ballooning forward

how owuld you manage REtinal detachment?
- Surgical vitrectomy
- Cryopexy/laser retinopexy
What symptoms might someone with AMD report?

What are symptoms of optic neuritis?
- REduced visual acuity
- Loss of red colour viison
- Central scotoma
- RAPD
What are features of optic neuritis on fundoscopy?
Unilateral swollen optic disc

How would you manage optic neuritis?
Methylprednisolone - MS most common cause

What are features of papilloedema on fundoscopy?
Bilateral swollen optic disc

How would you manage papilloedema?
Treat the cause

What are features on fundoscopy of acute angle closure glaucoma?
- Ciliary flush + mid dilated irregular pupils
- Optic disc cupping

How would you manage acute angle glaucoma?
- IV/PO acetazolamide
- Pilocarpine
- Timilol
- Consider mannitol/oral glycerol
