Abstract: 

Purpose: To evaluate the effect of two intravitreal bevacizumab (IVB) injections on peripapillary retinal nerve fiber layer (RNFL) thickness in patients with wet type age-related macular degeneration (ARMD).
Methods: This prospective interventional case series included 18 eyes of 18 patients receiving two IVB injections within a 6 weeks interval for treatment of wet type ARMD. Peripapillary RNFL thickness was measured prior to the first injection, and 12 and 24 weeks afterwards by optical coherence tomography (3D OCT?1000, Topcon Corporation, Tokyo, Japan). Mean RNFL thickness and values in the four peripapillary quadrants were compared at baseline, and 12 and 24 weeks after initial injection.
Results: Mean RNFL thickness was 89±21
mm at baseline which was significantly reduced to 82±15 mm at 12 weeks (P=0.021). At final follow?up (week 24), mean RNFL thickness reached 87±23 mm and was comparable to baseline values (P=0.356). Only the temporal quadrant showed a significant reduction in RNFL thickness at 12 weeks (P=0.033); this quadrant followed the same pattern of change as the mean RNFL thickness, becoming comparable to pre-injection values at 24 weeks (P=0.298).
Conclusion: RNFL thickness may decrease temporarily following two IVB injections in patients with wet type ARMD; however, in the long?term no significant change was detectable from baseline values.
