Tear caused by posterior vitreous detachment, degenerative retinal changes, trauma

In advance age, high myopes, after ocular surgery

Question 1

Retinal detachment?

And types?

Answer 1

Cleavage in plane between the neurosensory retina and RPE

3 types

III. Exudative

Question 2

Tractional retinal detachment?

Answer 2

Due to damage to RPE resulting in fluid accumulation in subretinal space
