1

What is the basic pathogenesis of diabetic retinopathy?

  1. Chronic hyperglycaemia
  2. Glycosylation of protein/basement membrane
  3. Loss of pericytes
  4. Microaneurysm
  5. Leakage and ischaemia

2

The following signs are characteristic of what?

  • Microaneurysms
  • Hard exudate
  • Cotton wool patches
  • Dot haemorrhages
  • Abnormalities of venous calibre
  • Intra-retinal microvascular abnormalities

Non-proliferative retinopathy

3

Why does the chance of retinal detachment increase with proliferative retinopathy?

Haemorrhaged vessels leads to fibrotic healing

Leads to contracture and retinal detachment

4

Why may patients with Rubeosis iridis have raised IOP?

New vessels grow into and block trabecual rmeshwork prevent drainage of aqueous humour

5

How do diabetic patients lose vision?

  1. Retinal oedema affceting fovea
  2. Vitreous haemorrhage
  3. Scarring/tractional retinal detachment

6

What are the two types of retinopathy?

  1. Non-proliferative
  2. Proliferative

7

How is diabeteic maculopathy treated?

  1. Optimaise diabetic management
  2. Laser
  3. Vitrectomy

8

The following signs are characteristic of what?

  • Attenuated blood vessels - copper or silver wiring
  • Cotton wool spots
  • Hard exudates
  • Retinal haemorrhage
  • Optic disc oedema

Hypertensive retinopathy

9

Which pathology will have vision loss which is painless yet very profound?

Central retinal artery occlusion

10

Giant cell arteritis is associated with which other condition?

Polymyalgia rheumatica

11

What is the most common cause of unilateral and bilateral proptosis?

Thyroid eye disease

12

Sjogren's syndrome consists of which triad?

  1. Keratoconjunctivitis sicca
  2. Xerostomia (dry mouth)
  3. Rheumatoid arthritis

13

  2. Occlusion of lacrimal glands
  3. Corneal ulcers

14

How can Marfan's syndrome affect the eyes?

  1. Short sighted
  2. Lens dislocation
