I don't know what you mean by 'many tests' and who did these tests. Were they non-physician optometrists, a general comprehensive ophthalmologist or a retina Eye MD specialist or neuro-opthalmologist. To "be sure" you should see a Eye MD ophthalmologist that specializes in retina disorders and surgery. Tests you would need include an OCT, fluoroscene angiography, visual field (peripheeral vision ) test.
