Comparison of Retinal Nerve Fiber Layer (RNFL) Thickness Measurements by Time-Domain and Spectral-Domain OCT In Glaucoma Patients

Comparison of RNFL Thickness Measurements by Time-Domain and Spectral-Domain OCT In Glaucoma Patients

Measurement of RNFL thickness by OCT is at a cornerstone for the correct diagnosis and monitoring of progression of glaucomatous optic neuropathy.

Spectral domain technology has enabled better reproducibility with better axial resolution in the measurement of RNFL thickness. A comparative study among Stratus, Cirrus and RT-View will enable clinicians to determine differences among various instruments.

Exclusion Criteria:

• Evidence of retinal disease
• Secondary glaucoma due to intraocular inflammation
• Lens induced glaucoma
• Neovascular glaucoma
• Tumor induced glaucoma
