Can moderate macular pucker cause retinal detachment? is that what doctor checks for on follow-up exams.

Check for swelling: of the retina and for worsening of vision. The pucker can wrinkle the underlying retina and cause cysts within it. If there is significant swelling, visual distortion, retinal disruption, then its a surgical treatment at that point. The pucker can stay unchanged for a long time or progress slowly but hard to predict. Good luck.
