Non Proliferative Diabetic Retinopathy

Question 1

What is non Proliferative DR

Answer 1

1. Retinal vessels become dilated
   *develop micro aneurysms
2. Small reinstall hemorrhages, cotton wool spots, hard exudates

Question 2

What happens early on in non Proliferative DR

Answer 2

1. Visual changes minimal or resolves after a few days
   *as it progresses retinal edema occurs
   *if it involves macular, visual acuity is affected = legal blindness

Question 3

What is seen during mild non Proliferative DR

Answer 3

1. Miscroaneurysms
   *early visible change in retinopathy during exam
   *scattered red spots in the retina where tiny weakened blood vessels have ballooned out

Question 4

What is seen during moderate non Proliferative DR

Answer 4

1. Blood vessels are blocked will begin to lead to edema

Question 5

What is seen during severe non Proliferative DR

Answer 5

Vessels are blocked, retina not getting blood supply
1. Hemorrhages
*bleeding occurs from damaged blood vessels leading to retinal layers
*can easily progress to proliferative retinopathy

Question 6

Is vision affected during severe non proliferative DR

Answer 6

1. No unless the hemorrhages occurs in or neat the macula
   *leaking blood can blur vision, makes the macula swell
