Objective

Fundus controlled perimetry with the scanning-laser Ophthalmoscope (SLO) has been established for determination of functional defects in the diagnosis of macular diseases. The static threshold test strategy has its limits in the delineation of small scotomas. Purpose of this study was to evaluate the value of fundus controlled kinetic perimetry in comparison with conventional kinetic perimetry (Goldmann) and the Amsler-charts.

Methods

In a retrospective study the results of 240 kinetic perimetries (SLO) in eyes with different macular diseases where a Goldmann visual field or an Amsler-chart existed were evaluated. A manual and an automated test strategy were used. The perimetric results were compared concerning delineation, size and location of the scotomata.

Results

Especially for the detection and delineation of circumscribed central retinal pathologies such as macular holes or neovascular membranes the kinetic perimetry with the SLO under simultaneous control of fundus and fixation is superior to conventional methods. In comparison to static threshold perimetry the detection of the borders of the scotomata is more precise and faster. A dislocation of the scotoma with extrafoveal fixation is only definable by use of a fundus controlled examination.

Conclusions

In the area of fundus controlled examinations with the SLO the kinetic perimetry allows an exact detection of scotomas within short examination time. An automated stimulus projection reduces the influence of the examiner by standardizing the projection rate. Kinetic fundus perimetry represents and instable or extrafoveal fixation a valuable device for correlation of morphologic and functional findings particularly for small scotomas and is superior to conventional methods.
