Corneal Scar

Can a corneal scar cause you to have visual field loss with no glaucoma present?

A visual field defect due to a corneal scar in visual axis  would likely look different that glaucoma. Know that a corneal scar can affect the accuracy of checking pressure in eye.   Be sure you are seeing an Eye MD ophthalmologist.  Ask about have an optic nerve OCT test to monitor your IOP rather than a visual field. Also ask about referring you to a corneal Eye MD to discuss using the eximer laser to try and remove the corneal scar if it is affecting your vision

Thank you Dr. that puts me at ease! I have lost vision in that eye due to the corneal scar. I noticed the difference immediately once my eye got better. and the Dr. that I saw said it wasn't directly right in the center but they showed me a picture and it was very very very close. I will mention this to my primary eye doctor at my next appointment! Now if there was some visual field loss in the area due to that corneal scar and I have to perform a visual field test will they be able to distinguish that was far as loss due to glaucoma as oppose to the loss due to the scar? My visual fields and optic nerve have always looked super healthy. But due to the fact that I have high eye pressures they check for that.

There is nothing in your posts to suggest the possibility of Fuchs dystrophy at all. Fuchs is not rare. I saw two patients with it today.  A corneal ulcer does not lead to Fuch's or glaucoma.

Hi Stephy:  I have been following your two posts.  I finally had to send you a letter.  
There is an inherited condition called Fuchs Corneal Dystrophy.  It is a rare condition and even more rare in one your age. But over 600 corneal thickness is one of the obvious signs. Your specialist, may not be aware of this condition let alone suspect someone of your age of having it.
It  will cause your eyesight to become cloudy, worse in the mornings and improving as the day continues.
Good News - however - _ this condition can be fixed and your eyes will service you well for many years.  
Good Luck  Donna

Yes if it was located in the center of the cornea (visual axis). Just in the eye with the scar.
