PURPOSE: To investigate the effect of optic nerve head drusen (ONHD) on retinal nerve fiber layer (RNFL) thickness during a follow-up period. METHODS: Twenty-three non-glaucomatous eyes with clinically visible ONHD confirmed by colored disc photos were studied. RNFL thickness was determined by optical coherence tomography (OCT). Eyes were re-examined after an average of 18 months (ranging from 14 to 22 months). Mean RNFL thickness of each quadrant was compared with previous results at each follow-up visit. RESULTS: Mean RNFL thickness was 88.43 ± 10.2 μm at first visit and 90.35 ± 6.9 μm at follow-up visits in eyes with clinically visible ONHD. The difference between the mean RNFL thickness measured from inferior, superior, nasal and temporal quadrant at first and follow-up visits was not significant (paired t test, p > 0.05). CONCLUSIONS: The presence of drusen was found to have no effect on RNFL thickness at follow-up visits. OCT may provide a useful means to evaluate and follow up RNFL thickness in these patients.
