Evaluation of oculokinetic perimetry.
METHODS
Oculokinetic perimetry (OKP) was performed on 98 patients (187 eyes) using the Damato 26-point glaucoma screening chart. Results were compared with those obtained from a 24-2 full threshold test on a Humphrey Field Analyser (HFA).


RESULTS
In its ability to detect pathology in individual eyes, OKP had a sensitivity of 75.0% and a specificity of 71.4%. To detect glaucoma, OKP demonstrated a sensitivity of 86.0% and a specificity of 56.1%. The number of OKP defects detected increased with increasing HFA mean defect and corrected pattern standard deviation. Whereas moderate and severe field defects were almost always detected, smaller and shallower glaucoma defects were often missed.


CONCLUSIONS
The fall in sensitivity and specificity of the OKP chart in identifying milder glaucomatous field defects diminishes its value as a screening test. However, its introduction into wider use in the community may increase awareness of glaucoma amongst general practitioners and members of the public, and help to detect previously undiagnosed glaucoma with moderate to severe damage. A normal OKP finding does not exclude the presence of early glaucoma. Combined with ophthalmoscopy, OKP may improve glaucoma detection rates amongst non-ophthalmologists.
