Tractional and Exudative Retinal Detachments

Question 1

Tractional Retinal Detachment

Answer 1

caused by contraction of fibrous tissue (from NV) on retinal surface that pulls retina
no break or liquefied vitreous required

Question 2

Causes of Tractional RD

Answer 2

*proliferative diabetic retinopathy
retinopathy of prematurity
proliferative vitreoretinopathy

Question 3

Symptoms of Tractional RD

Answer 3

little since slowly progresses
no flashes/ floaters
VF defect

Question 4

Signs of Tractional RD

Answer 4

detachment appears smooth and concave
initially shallow and does not go past ora
stationary
proliferative fibrous membrane

Question 5

Tx of Tractional RD

Answer 5

vitrectomy

membrane dissection

Question 6

Proliferative Vitreoretinopathy

Answer 6

cells migrate to surface of retina, form fibrous sheet- contracts causing rigid folds that can cause detachment
after RD repair

Question 7

Exudative Retinal Detachment

Answer 7

separation of retina from RPE by accumulation of fluid
fluid from breakdown of blood retinal barrier
no break required

Question 8

Causes of Exudative RD

Answer 8

Vascular- Coat’s disease
Inflammatory- post scleritis
Neoplastic- choroidal melanoma (NV)
Idiopathic

Question 9

Symptoms of Exudative RD

Answer 9

fluctuating visual changes

Question 10

Signs of Exudative RD

Answer 10

smooth convex/ dome shaped elevation of retina
subretinal fluid that can visibly shift
leopard spots from reabsorbed fluid
