Oral citicoline administration improved visual evoked potentials (VEP) in glaucoma patients, reducing latency and increasing amplitude. This suggests a potential therapeutic benefit for visual pathway function in glaucoma.

Area of Science:

  • Ophthalmology
  • Neuroscience
  • Pharmacology

Background:

  • Glaucoma and ocular hypertension are associated with slowed neural conduction in visual pathways, indicated by increased visual evoked potential (VEP) latency and reduced amplitude.
  • Previous studies indicated that intramuscular citicoline injections can improve VEP parameters.

Purpose of the Study:

  • To investigate the efficacy of orally administered citicoline in improving VEP latency and amplitude in patients with glaucoma.

Main Methods:

  • Twenty-one glaucomatous eyes were assessed for VEP latency and amplitude.
  • Participants underwent two bi-weekly courses of oral citicoline (1 gram/day), separated by a two-week break.
  • VEP measurements were taken before treatment and two weeks after the second treatment course.

Main Results:

  • A significant reduction in VEP latency was observed, from 123.5 ms to 111.9 ms (P=0.0008).
  • VEP amplitude showed a significant increase, from 6.56 to 7.88 (P=0.04).
  • 62% of the treated eyes demonstrated a positive response to oral citicoline.

Conclusions:

  • Oral citicoline administration can lead to improvements in visual evoked potentials in a subset of glaucoma patients.
  • The findings suggest that oral citicoline may be a viable option for enhancing visual pathway function in glaucoma management.
