What are the medical options for lazyeye?

Lazy eye. Depends on what you're calling lazy eye. If its a weak eye (doesn't see well) then if it's diagnosed during early childhood the options are medical and therapeutic. If you mean a crossed eye, or an eye that is not straight, then it really depends on the cause. Sometimes glasses will help, but more often surgery is needed. A good exam with a pediatric ophthalmologist is important.
Surgery vs Patching. For a child/infant, often the eye doctor may recommend patching or glasses, but for an adult, usually surgery is the only option.
