Influence of OSCAR-IB criteria on test–retest reliability of Spectralis SD-OCT retinal thickness measurements in people with Multiple Sclerosis

Puntos clave

• To evaluate the influence of OSCAR-IB criteria on the reliability of retinal thickness measurements in multiple sclerosis.
• Analyzed GCIPL and pRNFL thickness measurements using Spectralis SD-OCT.
• Assessed test-retest reliability of measurements with and without OSCAR-IB criteria violations.
• Compared findings with prior studies using Cirrus HD-OCT.
• OSCAR-IB violations minimally affected GCIPL reliability.
• pRNFL reliability was significantly reduced due to OSCAR-IB violations.
• GCIPL measures are suggested to be more robust than pRNFL measures.
