If the optic nerve seen as normal and not swell without to put drops to dilate the eyes can that change if drops was used to dilate the eyes?

No: If the nerve can be seen clearly without dilation, then the evaluation of the nerve is adequate. Dilating the eye just gives a better view into the back of the eye. ...Read more

See an eye doctor soon for a detailed examination, and if possible, bring any old records related to past eye treatments. ...Read more

Is it possible to save an eye from trauma if the optic nerve is intact?

Is it possible to save an eye from trauma if the optic nerve is intact?

Yes: It all depends on the extent of the injury. If the nerve is intact and you have vision in the eye it can be saved, but there may be injury to the globe, muscles, cornea, lens, or retina. Any significant trauma to eye that would cause such symptoms should be evaluated by an ophthalmologist. ...Read more

Eye pressure is the most simple to test but incomplete. To avoid or reduce progressive damage from glaucoma, careful monitoring by an ophthalmologist and treatment if necessary by eyedrops and/or surgery can be effective for controlling eye pressure. ...Read more

Well- check brain: If you are complaining of lack of well defined vision or there is something else odd about your vision that you can explain and the ophthalmologist gave you the thumbs up as far as the eyeball and its contents are concerned including the head of the optic nerve then, I believe someone will be sending you to see a neurologist very soon where they will look at the brain. Do you have headaches? ...Read more
