  • Abstract
  • Look Inside

We performed CFF (critical flicker frequency) studies in patients with diabetic retinopathy in order to evaluate the possible presence of optic nerve damage in this disease. Our of 114 eyes (57 subjects) with variable degrees of diabetic re-tinopathy, 46 eyes (40%) showed the value over 40Hz. Pathological value of less than 25Hz was observed in 13 eyes (11%). CFF value of less than 30Hz was found in 13 eyes (11%) in spite of visual acuity level over 0.1.

An impairment of CFF value was significantly correlated with presence of neovascularization from the optic disc.
