Ancillary Diagnostic Testing is available through both the Neurology and Ophthalmology Departments for:

• VER/VEP (visual evoked response/potentials) - A generalized evaluation of the visual conduction system using either a visual checkerboard pattern or flashing light stimulus
• ERG (electroretinography) – A multi-focal ERG, which checks the integrity of the retinal rods and cones
• EOG (electrooculography) - Tests the integrity of the retinal pigment epithelium and retinal pigment epithelial neuro-receptor interface

• Ophthalmic Diagnostic Imaging:

  • Ultrasounds to measure the eye, scan for intraocular masses, and detect ocular structure abnormalities
  • Retinal Photography and Angiography document optic nerve appearance and retinal vasculature in CNS disorders, diabetes, macular degeneration, etc.
  • Visual Field Testing (Humphrey Automated, Goldmann Kinetic, Tangent Field, Amsler Grid) – Each of these evaluate peripheral vision as well as central vision depending on the specific test utilized. 
  • Color Vision Testing (Ishihara, Farnsworth Munsel 100, D-15) can be generalized in determining total loss of color perception, partial color confusion among shades of red/green, or highly specific in determining red (protan), green (deutan), or blue/yellow (tritan) color vision disturbance.
  • Dark Adaptation
  • OCT (Optical Coherence Tomography) - An optical signal acquisition and processing method capturing micrometer-resolution, three-dimensional images of the inner eye.
