| Methods for measuring the visual field are perimetry, campimetry or noise field campimetry. |
|
| Until a few decades ago, campimetry was the standard of care but now is out of fashion. |
|
| Conventional perimetry and even campimetry provides information pertaining to the borderline between seeing and non-seeing areas. |
|
| With Damato campimetry we can measure the central visual field and the inner edge of the ring scotoma when it starts to develop. |
|
| The campimetry was not modified by the treatment and the blind spot enlargement was stable between the different exams. |
|
| This may be due to the fact, that the analysis was based on campimetry results that tested only positions within 30° of visual field. |
|
| Incorporating focal noise-field campimetry as a testing strategy for the proposed invention provides an extremely efficient method to determine significant visual field loss. |
|
| The distinction between spherical and polar coordinates should be formally made, since data of the visual field position can be obtained either with perimetry or campimetry. |
