Table 2.
Ocular parameters comparison between zebrafish and three different mammalian species. The table shows the influence of shortened axial length on front and back focal lengths, whole eye refractive power, estimated SLO field of view (FOV), change in raster scan density and estimated digital resolution. Italicized data are estimated and/or derived from other physical data parameters shown within the table.
| Species | References | Axial Length (mm) | Front Focal Length (mm) | Back Focal Length (mm) | Whole Eye Power (D) | SLO FOV (mm) | Change in Scan Density (%) | Digital Pixel Separation (μm/pixel) | |
