Definition of the parameters analysed in this study
| Polarimetric parameter | Definition |
|---|---|
| TSNIT average thickness | Average thickness (μm) for the pixels in the temporal (T), superior (S), nasal (N), and inferior (I) quadrants along the total measured ring |
| TSNIT standard deviation | The standard deviation (μm) of the retinal nerve fibre layer thickness (RNFLT) values in the temporal (T), superior (S), nasal (N), and inferior (I) quadrants along the measured ring |
| Superior average | The average RNFLT (μm) of the points along the superior 120° section of the ring |
| Inferior average | The average RNFLT (μm) of the points along the inferior 120° section of the ring |
| NFI | Nerve fibre indicator. An indicator of the probability that the eye suffers from glaucoma. It is generated by neural network technology, trained with data from normal to glaucomatous eyes. It represents a single, summary measure of the integrity of the entire RNFLT |
