Materials and Methods: This study enrolled eleven eyes with branch retinal vein occlusion implanted with dexamethasone implant. Central corneal thickness, anterior chamber depth, pupil diameter, keratometry (K) readings at the steepest meridian (steep K) and the flattest meridian (flat K), corneal astigmatism power, and cylinder axis were measured before and after intravitreal injection using the optical low-coherence reflectometry device and Scheimpflug analyzer. The degree of agreement between parameters was assessed using Bland-Altman plot analysis.

Results: Central corneal thickness, anterior chamber depth, pupil diameter, steep K, flat K, corneal astigmatism power, and cylinder axis measurements with the optical low-coherence reflectometry device and Scheimpflug analyzer showed narrow 95% limits of agreement (LoA), which implies good agreement between two measurements.

Conclusion: Both systems can be used interchangeably for all anterior segment measurements following intravitreal injection of dexamethasone implant. Keywords : intravitreal dexamethasone implant, optical low-coherence reflectometry, Scheimpflug analysis
