Original Study


Objectives The aim of the study was to evaluate the role of optical coherence tomography (OCT) in optic disc analysis in glaucoma patients. Background Forty patients underwent full ophthalmic examination, including a review of medical history, best-corrected visual acuity, slit-lamp biomicroscopy, intraocular pressure measurement, gonioscopy, dilated fundoscopic examination, automated perimetry, and OCT at 1 month and after 6 months. Patients and methods Stratus OCT was used for ocular imaging in patients with dilated pupils. All patients had optic nerve head and retinal nerve fiber layer thickness (RNFL) measured during the two visits. Quality assessment of stratus OCT scans was evaluated by an experienced examiner masked to the patient«SQ»s other test results. Good-quality scans had to have focused images from the ocular fundus, adequate signal strength (>6 for RNFL and macula scans), and the presence of a centered circular ring around the optic disc (for RNFL scans). Results There was a statistically significant difference between patients at 1 month and after 6 months as regards OCT (RNFL), especially with regard to the inferior quadrant, with the P value of the RNFL inferior quadrant, which was the most affected after 6 months, at 0.03 and the P value of the rim area being highly significant at 0.001. Conclusion An OCT would be significantly informative early in the disease course to diagnose a preperimetric glaucoma, to confirm on a visual field, and to follow up longitudinal glaucoma progression.
