The Performances of Spectral Domain Optical Coherence Tomography (OCT) for Distinguishing Glaucomatous Eyes

The Performances of Spectral Domain Optical Coherence Tomography for Distinguishing Between Normal Eyes, Glaucoma Suspect and Glaucomatous Eyes

The purpose of this study is to evaluate performances of each parameters of spectral domain (Cirrus) optical coherence tomography for distinguishing between normal eyes, glaucoma suspect and glaucomatous eyes

Aim to determine which parameter of cirrus OCT is best sensitivity and specificity for glaucoma detection

Inclusion Criteria:

• BCVA at least 20/60
• refractive error +/- 5 D Or astig +/- 3 D
• enrolled in 3 population group (glaucoma, glaucoma suspect or normal)

Exclusion Criteria:

• VA less than 20/60
• marked RF error
• previous ocular trauma or surgery
• unreliable visual field
• poor signal cirrus OCT (less than 7)
• other causes of optic nerve or macular disease other than glaucoma
