How is visual acuity preserved in bitemporal hemianopia?

Macular pucker.with distortion. Close-up vision great, distance vision not as good. Could macular pucker impair distance vision only and not close up?
Not likely : Macular pucker affects the retina which detects images at any distance. The lens and cornea focus images at various distances onto the retina. So a problem at only one distance usually is a problem other than the retina. However, some people may only notice distortion from a macular pucker at a particular distance. A review of your records/images would help clarify. ...Read more

Advanced Macular pucker & stable glaucoma in 1 eye. 2nd eye mild ERM. What is prognosis for adequate vision. Concerned that both eyes have disease.
Close follow up: Macular pucker can occur as a consequence of spontaneous pucker. There are procedures that can be done to help eliminate this but they carry some risk so usually the retinal surgeons who do this will wait for a level of lowered vision that is significant or note progression as a reason to intervene. The glaucoma is a separate issue for both eyes. These conditions should be closely monitored. ...Read more
