My husband has been diagnosed with pathological myopia. He has been extremely nearsighted (legally blind w/o his contacts) his entire life, but in the past few years he has developed floaters; also, he has difficulty reading because when he closes one eye the horizon curves down and when he closes the other eye, the horizon curves up so together he's got some double vision going on. Other than yearly exams to monitor, is there any other course of treatment he should be exploring?
