PURPOSE: To investigate the retinal nerve fiber layer thickness (RNFLT) in uveitic eyes and search for the associations with uveitis activity, etiology and location. METHODS: The files of 76 patients with uveitis and 76 controls were scanned. Associations of RNFLT were analyzed using generalized linear models. RESULTS: The RNFLT was significantly higher in patients with uveitis (p < .001). Active uveitis patients had a thicker RNFL than the controls and the patients with quiescent uveitis (p < .001). Anterior uveitis was associated with thinner RNFL in global and inferotemporal quadrant (p = .011 and 0.013, respectively). Thickening of RNFL was associated with posterior uveitis and Behçet's disease in all quadrants (p < .001) and idiopathic uveitis in the superonasal and nasal quadrants (p = .001). CONCLUSION: Active uveitis, as well as posterior uveitis and Behcet's disease-associated uveitis, is a major confounding factor in RNFL analysis and therefore detection of glaucoma.
