PURPOSE: To compare retinal nerve fiber layer (RNFL) thickness and ganglion cell-inner plexiform layer thickness (GCIPLT) in the affected eyes to fellow unaffected eyes of patients with unilateral Fuchs' uveitis syndrome (FUS) and analyze their change over time. METHODS: Twenty seven unilateral FUS patients who did not have concomitant systemic or ocular disease were retrospectively enrolled. Central macular thickness (CMT), RNFL thickness, and GCIPLT measurements were evaluated. Data was analyzed using the non-parametric Brunner-Langer model (LD-F2 design) and Wilcoxon signed-rank test. RESULTS: The mean age of the patients was 40.2 ± 10.2 years. The median disease duration was 11 (2-62) months. The median best-corrected visual acuity (BCVA) of the affected eyes and the fellow eyes was 0.22 (0.00-2.50) vs. 0.00 (0.0-0.10) logMAR at the initial visit and 0.05 (0.00-2.50) vs. 0.00 (0.0-0.30) logMAR at the final visit. The change in BCVA was found significant in the affected eyes, but not in the fellow eyes (p < 0.001 and p = 0.287, respectively). The median CMT in the affected eyes at the final visit was not statistically different from the value at the initial visit (255 (157-306) vs. 245 (140-310) µm, p = 0.256). The change in RNFL thickness over time in the affected eyes was similar to the fellow unaffected eyes of the patients with unilateral FUS at all quadrants, with non-significant time and group effects (p > 0.05). However, median GCIPLT in all quadrants (except superonasal) in the affected eyes was statistically lower than the fellow eyes at the initial and final visits (p < 0.05). The most affected quadrant of the ganglion cell complex was inferonasal in the involved eyes (79 (42-97) vs. 75 (43-87) µm) at initial and final visits (p = 0.033 for time effect and p < 0.001 for group effect, respectively). CONCLUSION: Median CMT and RNFL thickness did not change during follow-up in the affected eyes of patients with unilateral FUS. Median GCIPLT in the affected eyes declined over time in all quadrants. Ganglion cell loss was also most prominent in the inferonasal quadrant in the affected eyes. FUS patients should be followed up long-term in terms of ganglion cell loss, especially in the inferonasal quadrant.
