What type of retinal detachment is caused by neovascular membranes on the retinal surface contracting and tugging on the retina?

Rhegmatogenous
Tractional
Exudative
Hemorrhagic

Explanation

Answer: B - Tractional retinal detachment is caused by neovascular membranes on the retinal surface contracting and tugging at the retina.

Tractional retinal detachment occurs when the retina is pulled from its base. The neovascular membranes on the retinal surface contract in diseases like diabetic retinopathy. As scars get bigger, they can tug on the retina and detach it from the back of the eye.
