Confrontation methods (binocular face description and quandrant finger counting, red pin) | Relatively quick and easy, always available, cheap, can be performed at the bedside | Less sensitive than other methods, more difficult to compare results over time |
| | |
Goldmann/Octopus (kinetic) perimetry | Sensitive. Good for monitoring defects over time. Can asses for patient reliability | Requires a skilled operator; subject to interoperator variability. |
| | |
Humphrey/Octopus (static) perimetry | Sensitive, good for monitoring defects over time, can assess for patient reliability | Requires significant concentration, may produce artefacts if test conditions not correct (eg, spectacle rims). Impossible with sick patients |
