Sumary of Trust clinical correlations when using OCT to diagnose glaucoma:
- Thasarat S. Vajaranant “The thickness should not go down to zero, and that’s because of the vascular tissue,” Vajaranant said.
- Sometimes, associated pathologies such as falsely higher retinal nerve fiber layer thickness due to schisis or vitreous traction can appear on the scan, possibly affecting measurements, she said.
- Physicians should look for preferential retinal nerve fiber layer loss but should not solely rely on it.
- To avoid a false negative or false positive, it is important to look beyond preferential retinal nerve fiber layer thickness analyses and employ other techniques in addition to the OTC scan.
- Correlate clinical examinations with visual fields and have trust in those analyses, she said.
