Pepose Vision Institute uses the innovative NERVE FIBER ANALYZER (NFA) to perform a quick, thorough, noninvasive test for early signs of glaucoma. The NFA can detect nerve fiber loss and early onset glaucoma years before older testing methods don’t settle for anything less than an NFA test to monitor the health of your eyes! The NFA test allows for early intervention treatment options, before glaucoma has compromised your vision. Utilizing a unique combination of polarized light and scanning laser ophthalmoscopy, the NFA rapidly scans the retina and measures the thickness of the nerve fiber layer. The results reveal whether a patient is within/outside normal limits or borderline with respect to clinical indications for early glaucoma. This test does not require the patient’s eyes to be dilated. There are no bright flashes of light, no pain or discomfort. It is recommended for patients with pre-existing early stage glaucoma, or any patient considered at risk for glaucoma.
