Purpose: To evaluate the effects of retinal angiography, using fluorescein and indocyanine green dyes, on optical coherence tomography (OCT) measurements. Methods: In total, 76 eyes from 76 consecutive patients were included. Macular cube 512 x 128 combination scanning and optic disc 200 x 200 scanning using spectral-domain (SD)-OCT were performed twice, before and after retinal angiography, with fluorescein or indocyanine green. Signal strength, regional retinal thickness of the 9 Early Treatment Diabetic Retinopathy Study subfields, total macular volume, and retinal nerve fiber layer thickness obtained before and after angiography were compared. Repeatability was also investigated. Results: Comparing the results of OCT measured before and after retinal angiography, there was no statistically significant difference in any parameter assessed. The interclass correlation values for each measurement were all >0.808 (range 0.808-0.999). Conclusion : Retinal angiography using fluorescein and indocyanine green dyes has no significant effect on OCT measurements. (C) 2015 S. Karger AG, Basel
