Purpose: To evaluate the influence of active inflammation in uveitis on confocal scanning laser tomography (CSLT) and optical coherence tomography (OCT) measurements.
Methods: Prospective enrollment of patients (64 eyes) with non-infectious uveitis. Retinal nerve fiber layer (RNFL), rim-area and -volume for CSLT and Bruch's-membrane-opening minimum-rim-width (BMO-MRW) and retinal nerve fiber layer thickness (RNFL-O) for OCT were recorded.
Results: No significant differences between eyes with active inflammation (31) vs no inflammation (33) were observed for all investigated CSLT parameters and BMO-MRW. The RNFL-O in OCT was significantly increased (1st p = .0439, 2nd p = .0327, 3rd p = .0313) while actively inflamed. CSLT did not show a significant difference between glaucomatous and non-glaucomatous eyes albeit all OCT derived parameters did.
Conclusion: CSLT measurements were not affected by inflammation but unreliable in glaucomatous eyes. RNFL-O was significantly influenced by inflammation while BMO-MRW was not. BMO-MRW seems to be the best approach in uveitic eyes.
