Neurologic Evaluations in Normal Tension Glaucoma Workups: Are they Worth the Effort?



    Normal-tension glaucoma is a chronic progressive optic neuropathy of unknown etiology.

    Neuroimaging workup in these patients is controversial.


    To determine the value of routine neurologic and neuro-ophthalmologic evaluations in patients with NTG[1].


    We conducted a retrospective review of all patients diagnosed with NTG in our institution between 2001 and 2006. Neurologic and neuro-ophthalmologic data were evaluated.


    Sixty-eight patients were considered suitable for the study (35 males, 33 females age range 43–90 years). Neurologic and neuro-ophthalmologic findings were normal in all of them. The computed tomography brain scan was normal in 88% and duplex carotid Doppler scan was normal in 92%.


    Pathologic findings in neurologic and neuro-ophthalmologic assessments were uncommon in NTG. Therefore, contrary to earlier suggestions, neurologic and neuro-ophthalmologic evaluations in typical normal-tension glaucoma patients appear to have no added value.
